Challenging The Myths Of Permeable PavementWith the imminent trouble of urban flooding on the rise, permeable pavement (PP) is quickly gaining notoriety as a sleek and ethical solution. So, let’s challenge the myths of PP and clarify some of the annual, bi-annual, quarterly, and monthly maintenance misinformation surrounding these pavers.

Project Spotlight
Grimmwelt Kassel We’re all familiar with the tales from the Brothers Grimm, the 19th-century German authors whose stories still haunt and entertain us today. Their work still is being adapted into new books, movies, and TV shows today. And the brothers themselves are getting a little more recognition in their home country in the form of a new museum.

Design Trends
Things Are Looking Up In Hardscaping If you were to visit the site of a new building project and were asked to examine the hardscaping design, your natural inclination would be to look down at ground. In most instances, you wouldn’t be wrong in making that choice. But if you were to visit the site of 1200 Seventeenth Street in Washington, D.C., you would be encouraged to focus your gaze upward – to the roof.

On this very page, I have discussed in the past the importance of flu preparedness. I think it is a critical issue, so I wanted to write about it again. Every couple of years, I go through a lengthy battle with the seasonal flu – and I inevitably visualize all the work piling up on my desk during that time. I would bet that many of you do the same when you get sick. But if you’re properly prepared, then temporary illness won’t spell doom (or mean costly delays) for your projects.
Every year, thousands of American workers are sickened by the flu, and new strains make it even more difficult to contain or treat. Fortunately, most of us only will be briefly inconvenienced by the seasonal flu, but according to the Centers for Disease Control (CDC), more than 30,000 people in this country die from flu-related complications each year. So do you know if your employer is prepared to deal with the flu – or worse?
Avoid complications, missed deadlines, and angry clients by being prepared. Back up your computer files regularly, keep your team informed on all of your projects, and make sure your work schedule (i.e., important meetings and appoint-ments) is accessible to at least one coworker or your supervisor. There is a plethora of online tools to get you started if any of these programs are not already in place at your company. Google is a good place to start. We use Google’s online calendar (which has adjustable privacy settings) so everyone at Lionheart knows where our team members may be traveling or otherwise out of the office. This is a valuable tool since many of us are
scattered around the country, working remotely. We also value cloud storage for our editorial and sales files, and we hold regular conference calls to keep our colleagues up to speed on each maga-zine we publish.
An additional item to consider should the flu af-fect your offices is how to prevent further spread of the virus among your staff. The U.S. Depart-ment of Labor’s Occupational Safety and Health Administration (OSHA) has issued commonsense fact sheets that employers and workers can use to promote safety during flu season. The information is available on OSHA’s website.
As with most situations in life, preparation is the key to success. How prepared are you? wMD

Belden Brick Products Now Available from Acme Brick Company
Industry News
Acme Brick Company ’s Texas showrooms now offer the full line of architectural brick products from the Belden Brick Company of Canton, Ohio. Acme has the exclusive right to sell the Belden line in the state of Texas.
The Belden Brick Company is espe-cially well known for its extensive line of architectural brick that is available in many unusual sizes. The company also produces a line of sand mold brick that has a handmade look and an exten-sive collection of thin brick. See more at http://www.beldenbrick.com/thin-brick/.
In commenting on the new re-lationship, Stan McCarthy, Acme’s senior VP of sales for Texas, said, “Belden Brick is a great addition to our product offering in the state of Texas. Their product selection and quality are second to none in the industry. The addition of their prod-ucts provides us with a broad selec-tion of face brick, oversized brick, special shapes, pavers, and thin brick that will enhance our ability to provide more products in both the architectural and residential mar-kets. The Belden Brick and Acme Brick names are synonymous with outstanding quality and reputation, making our relationship to repre-sent their products a natural in the state of Texas.”
Acme Brick Company, founded in 1891, is the nation’s largest brickmaker. Acme owns 26 brick plants and has 70 company-owned sales offices across 15 states, plus a nationwide network of independent distributors. wMD

In April of 2015, New York City Mayor Bill de Bla-sio released One New York: The Plan for a Strong and Just City. The plan includes the ambitious goal of re-ducing carbon emissions in the Big Apple by 80 per-cent by 2050. Now, with the help of CarbonCure – a leader in green concrete technology – New York concrete masonry manufacturer Superior Block Corporation is helping the city get one step closer to achieving its carbon reduction goal.
Superior Block announced that as of No-vember 2015, its concrete masonry units will be available with CarbonCure by request. The Car-bonCure technology introduces carbon dioxide gas captured from the smokestacks of local indus-trial emitters into concrete products, where the gas becomes chemically converted into a mineral and permanently captured within the concrete.
“Superior Block has always proudly introduced sustainable concepts into its products and manufac-turing processes,” says Connie Cincotta, president of Superior Block. “For example, we’ve been offering products made with a high percentage of recycled waste material and supplementary cementitious material for years. Now, with the addition of Car-bonCure, we are immensely proud to introduce captured carbon dioxide gas into our mix and re-duce the carbon footprint of our concrete masonry products.”
CarbonCure has partnered with concrete ma-sonry facilities across North America, including An-chor in New Jersey, Oneonta Block in upstate New York, and A. Jandris & Sons in Massachusetts. With
multiple manufacturers surrounding the New York market, products made with the CarbonCure tech-nology may be competitively bid, which is an import-ant consideration for New York architects.
“I’m excited by the announcement of Supe-rior Block’s partnership with CarbonCure,” says Aaron Pine, principal at Construction Specifica-tions Inc., a specification consultant to many of New York’s leading architectural firms. “Our cli-ents value sustainability, and with the addition of Superior Block enabling competitive bidding on CarbonCure products, I feel more comfortable in-corporating CarbonCure into my client’s concrete masonry unit specifications.”wMD

New ‘How to’ Guide Provides Manufacturers with Clear Guidance on Meeting Latest LEED Certification RequirementsNonprofit Clean Production Action makes it easier to disclose and remove hazardous chemicals from building products.
“GreenScreen is helping to clarify the world of chemicals in building
products.” – Mark Rossi
A new report from Clean Production Action offers guidance for using its GreenScreen® for Safer Chemicals method to meet the LEED v4® verification requirements.
GreenScreen helps manufacturers, architects, and designers in identifying chemicals of concern and selecting safer alternatives. Using Green-Screen enables building professionals to meet green building requirements and choose safer ma-terials and products.
“The latest version of LEED building certification, along with increasing public concern for environmen-tal health, emphasizes identifying chemicals from build-ing products and using safer alternatives to those that are toxic,” said Mark Rossi, Ph.D., executive director of Clean Production Action. “GreenScreen is helping to clarify the world of chemicals in building products where disclosure is largely absent and knowledge of hazardous and safer chemicals is unknown.”
The newly released “How to Use GreenScreen® for LEED v4” provides an overview on LEED re-quirements and defines terms that are critical for meeting them. “The ‘How to’ guide is the outcome of a unique collaboration of manufacturers and users to provide clear guidance for meeting LEED require-ments,” said Annie Bevan, certification and opera-tions manager at Green Circle Certified, LLC.
Included in the Guide are directions on how man-ufacturers can get their Manufacturer Inventories or optimization claims certified for LEED v4 compliance. This certification will help architects, designers, and LEED project reviewers more easily identify product documentation that meets the requirements of the USGBC. Most importantly, the ‘How to’ guide charts a four-step process for using GreenScreen to deter-mine that products are compliant with the new LEED v4 requirements around building product disclosure and optimization, including:• Step 1: Product Inventory – Identify
comprehensive list of chemicals in products to the required thresholds (i.e. 1,000ppm or 100ppm)
• Step 2: Chemical Hazard Assessment – Use GreenScreen to determine the inherent hazards of chemicals.
GreenScreen has the added advantage of enabling manufacturers to identify and report the hazards of both proprietary and non-proprietary chemical ingredients. GreenScreen assessments are the more comprehensive option for reviewing hazards and generating Benchmark™ scores. The second option is the GreenScreen List Translator, which is based on a tool that maps GreenScreen Specified Lists to hazard classifications, and it results in List Translator Scores rather than GreenScreen Benchmark scores.
• Step 3: Reporting – Next, the report offers samples for how to fulfill LEED documentation submission requirements, which are categorized by disclosure and optimization.
• Step 4: (Optional): LEED-compliant verification – Lastly, the “How to” guide provides guidance on how to obtain LEED v4 compliance certification marks from GreenCircle Certified or Clean Production Action to enable easy identification of compliance with LEED v4. The USGBC incorporated transparency
into its building standards with its new LEED v4 standard in November of 2013. The new language offers points for using the GreenScreen for Safer Chemicals. The GreenScreen method is used by businesses like Hewlett-Packard, governments like Washington State, and NGOs such as the Healthy Building Network in their Pharos Project. You can learn more about the GreenScreen method here: http://www.greenscreenchemicals.org/method. wMD

GRIMMWELT KASSEL
New museum is dedicated to the literary legacy of the Brothers Grimm
PROJECT SPOTLIGHT
WE’RE ALL FAMILIAR WITH THE TALES FROM THE BROTHERS GRIMM, THE 19TH-CENTURY GERMAN AUTHORS WHOSE STORIES STILL HAUNT AND ENTERTAIN US TODAY. Their work – “Rumpelstiltskin,” “Cinderella,” “Rapunzel,” “Snow White,” and “Hansel & Gretel,” for example – still is being adapted into new books, movies, and TV shows today. And the brothers themselves are getting a little more recognition in their home country in the form of a new museum.
The Grimmwelt Kassel museum – a reinforced concrete and natural stone structure (Gauinger Travertin) – at the Weinberg in Kassel, Germany was designed to present the Brothers Grimm’s works. It translates the historical and topographical features of a surrounding park into a continuous open space and invites visitors to explore the exhibitions at their own pace. On display are a multitude of presentations about the Grimm Fairy Tales, the brothers’ biographies, and even personal artifacts from their homes.

Of course, at Masonry Design we are more interested in the structure itself. When we heard about the museum, we immediately contacted the architecture firm, kadawittfeldarchitektur, to find out more.
According to the firm, the museum is located in the picturesque Karl-saue Park on the slope of an area called Weinberg close to Kassel city center where it blends into the gently undulating landscape. Old stone steps, wall fragments, pergolas, planted terraces, and lush vegetation contribute toward the special atmosphere of the park. The new museum continues the topography of the surroundings in an accessible roof land-scape and thus provides the park with an open stairway that leads up to a terrace with a view across Kassel.
This design leads to a split-level arrangement in the interior. The tiered space is arranged around a central hall presenting the various
key subjects of the exhibition. Visitors experience a place with diverse atmo-sphere and one that focuses on German linguistics as well as the collection of the Grimm Fairy Tales. The foyer with a reception desk, a shop, and waiting area is a long space stretching the full depth of the building. It ends in a light café with a panorama of Karlsaue Park and the southern part of the city.
The reinforced concrete structure has an outer leaf of light-colored natu-ral travertine, roughly split with courses of varied height. The choice of material

is reminiscent of the former so-called Henschel Haus, the firm says, which was destroyed by an air raid in 1945 and was situated where the new museum now stands. Stone relics of an old stairway and wellhead are a reminder of the Haus, and will continue to be part of the new garden on the museum grounds with the effect that the new build is not only em-bedded in the urban landscape but also in the history of the landscape. Furthermore, the choice of material reflects properties of the local lime-stone found under the existing hill, once a vineyard.
“The building protrudes from this slope like a further rampart and literally invites vis-itors to explore and clamber the broad and slightly tapered stairway embedded in the southern facade that leads up to the roof: an accessible area ten meters above the ground measuring 2,000 square meters and

designed as a rising terraced landscape,” kadawittfeldarchitektur says of the Grimmwelt in a news release. “The exterior walls are drawn up beyond the roof level as parapets and stepped to match the level of the roof landscape. A variety of events can take place on the spacious terrace – even outside opening hours – in order to make up for the valuable space lost to public use by the museum.
The ups and downs of paths through the terraced park, the stair-ways and alternating levels are continued inside – in a sense, it is a
building designed to persist with its environment and not only in it, the firm says. It is a museum that does not only want to present contents, but also mediate their existence in a playful

Its full-height, pearly white and fine-grain plastered walls are used as projection surfaces and are thus part of the exhibition. But more than anything else, the space functions as a distributor; this is where visitors start to understand the impact the terraced structure has on the interior’s arrangement, kadawittfeldarchitektur says.

staggered planes designed according to the split-level principle. The height of the introductory room allows views into all four publicly accessible areas of the museum, thus connecting the different contents within the 1,600-square-meter exhibition space.
Further, the sloped ceiling of the café traces the outdoor stairway on the southern side of the building. Oak paneling has been used as a refer-ence to the frequently repeated theme of the forest in the Grimm Fairy Tales. The ceiling in the foyer, as is the case for all other areas in the museum except for the offices and ancillary rooms, also is sloped; right angles are an exception throughout the entire building. Most floors are finished in light terrazzo.
The exhibition areas have a life of their own due to the clear layout of space and can therefore be devoted to a variety of different subjects.
The small windows on level 1 only allow diffuse light to penetrate into the exhibi-tion space. Levels 1 and 2 accommodate the permanent exhibits. The museum concept designed by Holzer Kobler Ar-chitekturen and hürlimann+lepp is orga-nized according to individual letters and terms taken from the Brothers Grimm’s German Dictionary. The entry-level area also provides access to the highest level (E1) with 400 square meters for chang-ing exhibitions and a ceiling with white lamella panels. wMD

THE MYTHS OF
Fall 2015 | MasonryDesign | 27www.masonrydesignmagazine.com | 27
WITH THE IMMINENT TROUBLE OF URBAN FLOODING ON THE RISE, PERMEABLE PAVEMENT (PP) is quickly gaining notoriety as a sleek and ethical solution. Unfortunately, with any great advancement comes cynicism. It’s like JKF said: “Change is the law of life. And those who look only to the past or present are certain to miss the future.” So, let’s challenge the myths of PP. Below we clarify some of the annual, bi-annual, quarterly, and monthly maintenance misinformation surrounding these pavers:

1) My ten-ton static roller will solve all my compaction problems.
Really? Will it really? Will it work with the American Society for Test-ing and Materials (ASTM) two-inch #8 bedding layer? What about the ASTM four-inch base #57 stone layer? Guess we’re just going to ignore the ASTM #2 and #3’s sub-base stone? Oh, and, what’s the respective lift height and level of moisture for this particular PP installation? More questions are generated than answered by statements like that above. So, lets break it down: If compaction is the process by which the bulk density of an aggregate of matter increases by mechanically driving out air, then to properly increase the density of an aggregate it only makes sense that you absolutely have to know what you’re compacting. If not, you’ll have no idea what the product’s moisture percentage is, what its maximum density is (in other words, when to stop), and the fundamental equipment needed to ensure that nothing goes wrong.
If you’ve successfully convinced yourself that the consolidation of ag-gregate layers is your Hail Mary, don’t forget that doing so simply means that your equipment is pushing the stone into the sub-grade or surround-ing excavated side soils; that’s displacement, not compaction.

2) In certain climates, traffic loads, and soil conditions a contractor can skip the sub-base in order to save the consumer some money.
No. The explanation to why this statement is so wrong lies in geotextiles and geo-grids, which are both important components of proper structural and hydrologic decisions. For one, geo-synthetic products can add major value and efficiency to PP applications. They can be used to segregate and further the performance in four different scenarios
1. Between the sub-grade soil and sub-base (or base)2. Between the sub-base and base3. Between the base and bedding4. In some designs, intermittently in lifts of the sub-base or base.

Fall 2015 | MasonryDesign
Geo-synthetic products add integrity and are a little investment compared to alternative initial and lifecy-cle costs. They also aid in filtration of petroleum from stormwater via microbial generation; prevent downward migration of aggregate into preceding layers under the kinetic energy of traffic and; special bonus, are easy to install.
3) Analyzing the renovation site is a long and grueling process.
The site analysis process is nothing to dread. I call this one Pete’s PP Precedents:
1. Start with a common percolation test of on-site soils. It can cost you as little as $100 and is crucial for any PP installation.
2. Make sure you get a soil analysis done for sieve size, bearing ability, and classification. It should set you back a few hundred dollars if done by a geotechnical firm or university annex.
3. Consult the PP and spec guide sections on your man-ufacturer’s website. Be sure to look out for recom-mendations on wearing course and cross section of installation options.
4. Step 4 is situational. In critical applications with ad-jacent subterranean drainage structures, bio-swales, vegetated filter strips, rain-harvesting components, etc., consult an engineer armed with permeable de-sign software.
MasonryDesign | Fall 201532 | Materials • Technology • Trends
MATERIALS | PAVERS
5. In residential, light commercial, and municipal applications, work with your town officials and product producers to design a PP that pleases the property owner, but that also solidifies your company’s commit-ment to sustainability.
6. You’re done in my book; take the jump and hit the ground running.
4) Annual, bi-annual, quarterly, and monthly maintenance will be needed after installing PP.
It’s a myth! It’s a myth! It’s a myth! I promise, I’m not the boy who cried wolf. Here are a few things that may affect the level of maintenance:
1. Environment (like shredding trees)2. Wind and snow (piled) born debris3. Pedestrian and vehicular pollutants4. Quality of Erosion and Sediment (E&S) measures5. Joint width and jointing material6. Etc.
So how often will maintenance really be required? Depending on your total site’s rate of infiltration, maintenance may either never be needed or at incredibly infrequent intervals nearing the 10+ year mark. Still worried about weeds, ants, etc.? Don’t worry, jointing aggregate on the surface is an exaggerated issue and only a concern in rapid water flow situations like flooding or power washing pavement. Weeds, ants and so forth are prevalent in any outdoor pave-ment, but are, thankfully, easily addressed with common household and gardening remedies.
5) Manufacturers of PP systems should not always test their products for Americans with Disabilities Act (ADA) compliance.
Manufacturers of PP systems such as Te-cho-Bloc, test their products for ADA com-pliance every single time. Whether or not the
ADA is applicable, testing to a standard has everyday residential relevance (i.e., children, elderly, steep slopes, etc.). The act requires that the pavement be firm, stable, and skid resistant. But, wait, what exactly does that mean?
1. ‘Firm’ applies to the rigid units in PP. Block units must pass stringent tests in order to be durable to everyday wear and tear.
2. ‘Stability’ is subject to the pavement cross-section and design. If the aggregate layers, geo-synthetics, pre-cast curb edging (etc.) are installed correctly, then pavement will be stable under foot, tired and static or dead loads.
3. ‘Skid Resistance’ has to do with the Brungraber Mark 2 test, which uses a pendulum and simulated human skin to determine if a product is safe to walk on with a shoed foot, wheel chair, etc., in even the worst case scenario.
Moral of the story? Comply with ADA standards and give your lawyers a break.

6) Permeable Pavements can only be set in certain patterns for interlock.
Myth #6 is at the core of a very heated debate. Essentially, the word “inter-locking,” as it pertains to permeable pavement, is referred to in many different ways. Some manufacturers have chosen to call it SPP (Segmental Permeable Pavements), while the Interlocking Concrete Pavement Institute refers to it as PCIP (Permeable Interlocking Concrete Pavement). At the base of it all, “in-terlocking” as it pertains to permeable pavement is defined as vertical (jointing sand), horizontal (pattern), and rotational (thickness) unit paving systems. As such, the generally accepted rule, in the industry, is that patterns with the least aligning joints have the most strength and interlock stability.
However, Techo-Bloc proved this concept wrong first in its Chambly, QC (300,000 sq. ft.) stocking yard and then at the Lamtec commercial site (80,000 sq. ft.) in PA. Both instillations utilized Techo-Bloc’s Inflo permeable pavement, which was mechanically set using the TB100si proprietary-vacuum-laying-de-vice. The aforementioned properties constantly undergo heavy, industrial traffic moving in many different directions. And yet, the PP running bone pattern that was installed was done so at no cost to load traffic quality. Both have been performing beyond expectation for five years now and have not exhibited any “creep” horizontal movement. Now that’s pushing the boundaries!
If by airing these myths a debate has begun, mission accomplished! “Let’s not play the game, let’s change it.” (Margaret Heffernan) At Techo-Bloc, we don’t believe in following, we believe in redefining. Let’s get the conversation started; what do you think? wMD

IF YOU WERE TO VISIT THE SITE OF A NEW BUILDING PROJECT AND WERE ASKED TO EXAMINE THE HARDSCAPING DESIGN, your natural inclination would be to look down at ground. In most instances, you wouldn’t be wrong in making that choice. But if you were to visit the site of 1200 Seventeenth Street in Washington, D.C., you would be encouraged to focus your gaze upward – to the roof.
According to ZGF, 1200 Seventeenth Street is a 170,000 square-foot “trophy quality” spec office building, developed and co-owned by Akridge and Mitsui Fudosan America. Sitework began in August of 2012 with the demolition of an existing eight-story, 1960’s office building that once was the headquar-ters for the National Restaurant Association. Con-struction for the new, 11-story building began in January 2013 and was completed in August 2014.
The $39-million building (total development cost was about $130 million) includes a full complement of office building amenities, including ground-level retail, 3.5 levels of below-grade parking, a fitness center, and two spec suites. The building’s primary interior feature is a 3,000 square-foot, two-story lobby consisting of a Chinese Travertine floor, and Brazilian Cherry and Greek Marble feature walls that accentuate the building’s diagonal composition.

“It’s a jewel box of a building,” Benjamin Meisel, managing director of leasing for Akridge, told The Washington Business Journal earlier this year. “From the standpoint of location and efficiency, it meets the needs of law firms today. This is the most efficient building in the city by far.” The law firm Pillsbury Winthrop Shaw Pittman LLP was the building’s first tenant.
At Eye LevelBefore we look up at the new1200 Seventeenth Street, let’s keep our
focus at eye level. ZGF’s design takes full advantage of the site’s unique characteristics: a highly visible location on a triangular parcel fronting Rhode Island Avenue; a completely unobstructed perimeter on all sides; and spectacular views of landmark buildings and urban spaces in three directions

– including the Washington Monument, Jefferson Memorial, St. Matthew’s Cathedral, and other notable landmarks.
The site’s prominence and exceptional geometry allow great opportu-nities for a distinctive architectural statement, the firm says. The building design is inspired by its site, located at the edge of Downtown and the historic DuPont Circle neighborhood – between the Farragut North and Dupont Circle Metro stations, if you’re familiar with Washington, D.C. It incorporates a historically inspired glazed terra cotta façade, juxtaposed against a modern glass tower that visually connects the two distinct neigh-borhoods. The result is described by ZGF as a light, dignified, contem-porary expression with floor-to-ceiling glass, while reflecting the material palette and texture of the surrounding historic environment.
Working with the owners, ZGF chose the building’s exterior materials with an eye to-ward the neighboring brick structures. 1200 Seventeenth Street is clad in pre-cast concrete panels faced with a custom-glazed terra cotta panel that relates to the scale and color of the masonry used in the neighboring historic build-ings. When discussing this, ZGF Associate Part-ner Allen Beall said, “The building’s design and materials are intentionally timeless. The form and expression acknowledge the basics of archi-tectural scale, while the glazed terra cotta used in conjunction with stainless steel promise an enduring finish.”
The building’s streetscape was designed with the pedestrian experience in mind. The building’s exterior base and perimeter pav-ing are accentuated by a 3cm Absolute Black Granite with thermal finish. The street level

planters are clad in the same black granite, and include Ipe wood benches with stainless steel trim and custom design wrought iron planter fences, providing a unique streetscape and highly utilized public amenity. The black granite is con-trasted by a light precast concrete paving, which address the historic neighbor-hood scale. Also noted by ZGF Landscape Design Associate Greg Matto, “The
site previously included a small, underutilized remnant park at the end of Rhode Island Ave-nue and 17th Street, which the neighborhood wanted replaced. Through design and coordi-nation with the city, ZGF was able to distribute publically accessible green space throughout the site with extensive at-grade planters, benches, native plantings and shade trees.” ZGF also pushed to maintain two existing wil-low oaks in order to preserve the mature tree canopy which characterizes Rhode Island Ave-nue, helping to tie the building and landscape into the existing neighborhood.
The building’s primary interior feature is a highly visible two-story corner glass lobby, high-lighted by wood and white marble walls that accentuate the building’s diagonal composition. The wall stone is a 3cm A2 Grade Greek Thas-sos, while the floor is a 2cm Chinese Travertine. The range of the interior stone was highly con-trolled through design specifications, slab selec-tion, and full-scale dry lays approved by ZGF in Greece.

The building’s prominent glass volume terminates at the roof terrace, framing two outdoor spaces that overlook the city and pro-vide a variety of intimately scaled spaces with catering facilities for casual gatherings and events. The more open areas are at the perimeter, with views of DC’s most famous landmarks; while the more intimate spaces are created through the placement of planters, shade structures, and cus-tom seating.
The inviting atmosphere is achieved in part by its warm palette of natural materials. Corten steel planters fabricated by Planterworx accommodate a variety of plantings, including mature Crepe Myrtle trees, and Custom fab-
ricated Ipe trellis’s by Landscape Forms and outdoor furniture by Janus contribute to the rooftop’s comfortable setting. Hanover pre-cast concrete pavers with char-coal accent bands reinforce the building’s diagonal movement and allow water to be captured and re-tained, contributing to the building’s LEED-Platinum rating.
Beall noted: “At the roof level, the tower ’s massing certainly challenged our engineers to be creative, but navigating the city approvals for height and projec-tions was the most critical ele-ment, which ultimately resulted in the greatest payoff.” wMD

found on vertical and horizontal surfaces such as sidewalks, patios, block walls, driveways and pool decks. They also can be used on exterior natural stone surfaces such as flagstone, slate, travertine, limestone, and sandstone.
SEK-Surebondwww.sek.us.comEveryone is talking about one of SEK-Surebond’s newest
sealers: SB-8700 Wet Look Joint Stabilizing Sealer with Antifun-gal. SB-8700 is a dual-purpose sealer that seals the surface with a luxurious, enhanced wet look and stabilizes joint sand to keep it from washing out of the joints. Joint sand that has been stabilized (hardened) also will resist weed growth and insect infestation. Because of its added anti-fungal agent, SB-8700 will prevent mold, algae, and moss growth. After application, SB-8700 is rain-safe within 90 minutes so you will no longer have to wait for the perfect weather day as with other sealers that may require 24 hours of cure time before they can get wet. SB-8700 is a premium solvent-based acrylic polymer sealer with exceptional breathability designed for immediate application after a new in-stallation. SB-8700 will enhance new hardscapes and bring old ones back to life.
PolySweep Polymeric Sandwww.sek.us.comSEK-Surebond introduced PolySweep Polymeric Sand in
2009 due to inconsistent performance of some brands of poly-meric sand at that time. PolySweep with Clear Set Technology is made with only high-quality clear polymers and NO portland cement. PolySweep is the #1 choice because it is guaranteed not to leave a haze on the surface after proper installation, the manufacturer says. PolySweep has superior strength and will perform consistently on every project. Use PolySweep for joints up to ¾” and X-Treme Wide Joint PolySweep for joints up to 4” with pavers, natural stone, cast stone, cobblestone, concrete overlays, and pool decks. The sand is available in tan, gray, and russet brown. wMD
