David Ball Group – Our Story

www.pudlo.com

Sustainable materials for the built environment.

David Ball Group plc embraces a 130 year legacy of materials innovation dedicated to the advancement of quality and performance in the challenging arenas of construction and industry.

Engineering materials are our business.

For almost half a century, David Ball Specialist Sands has set the bar in the preparation and supply of British standard and unique, ultra high quality sands for process testing and manufacturing. Quality that has travelled worldwide to meet the most exacting applications.

Durable construction is our strength.

Research & Development is at the heart of what the Group does, harnessing the power of chemistry to enhance the long-term performance of built structures with a dynamic brand portfolio.

Concrete innovation is our passion.

In the 1990s, the performance of integrally waterproof concrete was taken to a new level by David Ball Group plc as it reformulated PUDLO, the world’s first commercial concrete waterproofing admixture introduced a century before. Re-engineered around modern architectural needs, its enhanced capabilities came with the first – and still unmatched – guarantee of the completed concrete structure.

From PUDLO’s early use in the pioneering sanitation systems of Victorian London, its success story continues at the cutting edge in projects like London’s Crossrail and the celebrated Dubai Fountains.

Sustainable progress is our commitment.

While being the world’s most used building material, modern concrete is not recognised as one of the most sustainable. Today’s cement and concrete industries have a consistently impressive record for carbon reduction marshalled by a strong commitment to their environmental responsibilities.

A major milestone in this sustainable legacy is Cemfree, a totally cement free alternative to conventional concrete and a ground-breaking addition to David Ball Group plc’s portfolio. With the ability to produce structural concrete without the use of Portland cement, this revolutionary material is the result of years of dedicated development by the Group’s research scientists.

PUDLO: CHANGING PERCEPTIONS OF WHAT CONCRETE CAN DO

PUDLO Technical Information & Certification

Durability

Durability is the ability of concrete to resist weathering action, chemical attack, and abrasion

while maintaining its desired engineering properties. Different concretes require different

degrees of durability depending on the exposure environment and the properties desired.

Concrete ingredients, the proportioning, performance, placing and curing practices, and the

service environment determine the ultimate durability and life of the concrete.

The use of PUDLO CWP causes the reduction of the ingress of water within concrete through

flow under pressure as well as absorption.

The impermeability (waterproofing) is the single most important performance

characteristic with respect to preventing the ingress of the aggressive

substances within the concrete, and thus the biggest influence on long term

durability.

The benefits of using PUDLO CWP modified concrete thereof are discussed in more detail

below.

Permeability

Permeability is a flow property of concrete which quantitatively characterises the ease by

which a fluid will pass through it, under a pressure differential.

Capillary pore size and pore interconnections are important factors affecting permeability of

concrete. Pudlo modified durable concrete exhibits reduced capillary pore size and increase

the tortuosity of pore networks by densifying the microstructure and physically blocking the

pores to reduce the movement of moisture due to hydrostatic pressure.

The reduction in permeability and the associated decrease in the rate of the ingress of the

aggressive substances within concrete is one of the most important attributes in relation to

enhancement of the durability of concrete (Hewlett, 1998).

Absorption

Absorption is a process by which concrete takes in water by capillary action. Factors

affecting absorption are moisture gradient, capillary pore size and pore interconnection.

The hydrophobic properties of Pudlo significantly reduce the capillary suction. Thus modified

by the addition of Pudlo has very low water absorption values. -

PUDLO AND CONCRETE DURABILITY

www.pudlo.com

Diffusion & Chloride Induced Corrosion

Diffusion and Chloride Induced Corrosion is a process by which water, vapour gas or ions

can pass through concrete under the action of a concentration gradient. This, in the case of

for example chloride ions can cause corrosion of the reinforcing steel.

Pudlo modified durable concrete effectively protects the steel reinforcement from corrosion

induced by both chloride ingression and carbonation process by reducing the diffusion rate

of the aggressive substances by modifying the pore structure of the hardened concrete.

Sulphate Attack

Sulphate attack is characterised by the chemical reaction between sulphate ions from the

ground water with aluminate and calcium component of hardened Portland cement. The

reaction leads to the formation of expansive gypsum and ettringite. This causes expansion

leading to cracking, allows further ingress of sulphate and accelerates the degradation

process.

By reducing the permeation properties, Pudlo makes concrete water resistant, therefore

Pudlo treated concrete is more resistant to sulphate attack.

Pudlo to provide durability

The unique properties of Pudlo densify the cement paste by reducing the porosity and pore

sizes. This enhanced microstructure reduces the permeability and diffusion properties of

Pudlo modified concrete making into a high performance and durable concrete. It also

significantly reduces the absorption of concrete by providing hydrophobic lining in any

remaining micro pore walls, thus reducing capillary suction of pores.

By reducing the permeability, absorption and diffusion into concrete, Pudlo CWP makes the

concrete considerably more water resistant with a fivefold reduction in permeability relative

to the control concrete. Such attributes are key factors for minimising steel corrosion,

providing greater chloride and sulphate resistance and thus a more durable concrete and

resistance against other physical and chemical attack.

PUDLO to enhance compressive strength

Beside enhancing durability and water tightness of concrete, PUDLO CWP improves the

compressive strength of concrete significantly. Unlike other hydrophobic waterproofing

admixture where concrete normally lose compressive strength, the densified microstructure

of PUDLO modified concrete enhances its mechanical properties including compressive

strengths providing ease of mind to concrete producers and contractors alike. This additional

improvement of strengths eliminate any needs of the addition of extra cement which may

require for other type of admixtures.

www.pudlo.com

PUDLO to assist on slump and workability retention

One of the unique properties of PUDLO modified durable concrete is to help prolonging the

retention of slump which is extremely useful in extreme hot weather concreting condition in

the Middle East. This unique characteristics help both ready-mix concrete producers and

contractors to produce, deliver, place and consolidate concrete with right consistency

resulting into well compacted, homogeneous concrete matrix, a key requirement for durable

structure. As Pudlo modified concrete generally do not experience rapid loss of slump,

therefore the quality of delivered concrete remains assured as the risks of any deliberate

attempt to add unauthorized water are eliminated.

PUDLO to produce stable dense microstructure

PUDLO CWP produces additional hydrates and physically fills the interstitial spaces between

cement particles and capillary pores providing a dense microstructure. PUDLO produces the

first and final defence against any ingress of water which often carries dissolved salts to

attack hydrates and initiate steel corrosion. Pudlo CWP does not leach out under extreme

hydrostatic pressure as it has already been reacted to form stable hydrate structures. Pudlo

CWP is the best performing admixture on the market.

PRODUCT DATA SHEET

DOSAGE AND MIXING INSTRUCTIONS

The optimum dosage of PUDLO Cement Waterproofing Powder to meet specific requirements should always be

determined by trials using materials and conditions that will be experienced in use.

As a guide, normal dosages of PUDLO Cement Waterproofing Powder should be in the range 2 – 3% by weight of

cement. For example, 1kg PUDLO CWP per 50kg of cement.

To obtain maximum benefit it is recommended that the water cement

ratio should not exceed 0.40.

With the correct dosage of PUDLO Cement Waterproofing Powder

determined, the required amount should be added to the mix,

preferably with or immediately after cement addition.

The concrete or mortar produced must be thoroughly mixed until

homogeneous.

APPLICATION AND USE

It is essential that good concreting practice is performed and maintained at every stage of the application process.

Concrete modified with PUDLO powder should be placed without segregation, fully compacted and correctly cured

in accordance with up to date industry guidelines. Failure to adhere to guidelines and methods of good concrete

practice can cause segregation and under compaction and may result in moisture or water ingress.

PUDLO CASE STUDY – YAS MARINA VICEROY HOTEL

PUDLO waterproofs Yas Island Abu Dhabi premier hotel The Yas Marina Viceroy Hotel is the perfect combination of style and function. The construction of this iconic five star hotel straddles Abu Dhabi’s Formula 1 racetrack and is cloaked with an illuminated ‘gridshell’ to provide energy efficiency and create a striking landmark. The development is a five star signature hotel built alongside and over the Yas Marina Racing Circuit, developed by Aldar, designed by New York's Asymptote and built by Al Futtaim Carillion LLC with the support of more than 70 specialist subcontractors from around the world.


The jewel-like design includes the gridshell as an atmospheric-like veil over the two towers and a link bridge that passes above the Formula 1 track. The breathtaking architecture 'performs' as both an environmentally responsive solution and a visual spectacle and event. The gridshell contains 5,096 individually sized panes of glass and 2,100 tonnes of support steel. The 5,389 custom-made LED lights can be programmed to provide stunning illumination & optical effects. Over 15,000m3 PUDLO modified waterproof concrete has been used in the pile-caps, basement raft, retaining walls, tie-beams, bridge columns, slabs, tunnel base and tunnel walls of both Tower A & Tower B. PUDLO was also used in the basement car park water tanks. The project was completed in just 89 weeks; working 7 days a week and 24 hours a day. The total floor area is 105,000m2, delivered through a frame of 68,000 m3 of concrete, with 17,500 tonnes of reinforcement used in the concrete frame.

Designers: Asymptote Architecture.

Contractors: M/s. Al Futtaim Carillion.


PUDLO CASE STUDY – DUBAI FOUNTAINS

World’s longest serving water-proofing admixture completes concrete formula for world class Dubai Fountain When Emaar unveiled the Dubai Fountain, it had created yet another visually dynamic feat of engineering to enrich Dubai’s iconic landscape. The world's tallest performing fountain, it is a dazzling fusion of water, light and music designed by California-based WET, the creators of the Fountains of Bellagio in Las Vegas. Powerful mechanisms shoot jets as high as 500 ft (150 metres), equivalent to a 50-storey building, keeping 22,000 gallons of water airborne at any one time. Over 6,600 lights and 50 colour projectors create a palette of over 1,000 different light displays synchronized with classical, Arabic and world music. Set on the 30-acre Burj Khalifa Lake in downtown Dubai, the fountain sits alongside Burj Khalifa, the world's tallest building, and The Dubai Mall, one of the world's largest shopping and entertainment destinations.


Like its illustrious neighbours, the fountain is the product of world class engineering and the spirit of innovation and excellence which have made Dubai one of the world’s leading tourism destinations. An important part of the technical achievement that sustains the fountain’s dazzling displays, day after day, is hidden well below the water. Structurally, Dubai’s masterpiece consists of five circular fountains and two arcs contained by a 275 m (900 ft) artificial lake. Below the bed of the lake are fully submerged, interconnected tunnels containing critical fountain operating equipment, control rooms, and miles and miles of cable. The concrete formulation for the tunnels, including the all-important water-proofing specification, was a particular challenge of the project. Intended as an enduring attraction for Dubai’s retail heart, longevity and reliability were paramount in the materials engineering and casting of the concrete. The concrete mix for the tunnel structures, cast using some 22,000 m3 of concrete, included integral water-proofing provided by PUDLO admixture. PUDLO Inspectors from both the UK and UAE visited the site during the initial stages to consult with members of the project team from Hyder Consulting and Al Futtaim Carillion. Technical aspects of the final concrete formulation were resolved as well as the ‘design’ of the pour - aspect ratios, layouts and reinforcement - for the best outcome. PUDLO’s local Inspectors supervised the project on site throughout, from quality checking the concrete batching plants to overseeing all the pours. This level of technical support and inspection was one of the reasons why PUDLO was used to meet this prestigious project’s rigorous performance demands. The lake fountains were inaugurated in May 2009 by His Highness Sheikh Mohammed Bin Rashid Al Maktoum, Vice President and Prime Minister of UAE and Ruler of Dubai. Client: Emaar Properties PJSC. Consultants: Turner International & Hyder Consulting M.E. Ltd Contractors: Al Futtaim Carillion.

PUDLO concrete has been used inthe construction of mechanicalbiological reactors at Southwark’sIntegrated Waste ManagementFacility (IWMF) which have beendesigned to withstand chemicalleachate and high processtemperatures.

Veolia Environmental Services wasawarded the 25-year £60M PFIcontract to deliver and operate thegroundbreaking facility for LondonBorough of Southwark. Maincontractor, VolkerFitzpatrick, undertookthe project as a design and buildworking closely with consultingengineers, Royal Haskoning.

Located on a former gasworks on theOld Kent Road, the site also includes amaterials recovery facility, householdwaste, reuse and recycling centre, andwaste transfer station. It handles upto 200,000 tonnes of material peryear, processing all of Southwark’shousehold waste as close to sourceas possible and reducing the amountsent to landfill.

The mechanical biological treatment(MBT) plant, with 87,500 tonnes perannum capacity, is Veolia’s first in theUK.

Composting takes place in two sets ofsix reinforced concrete tunnels, eachstructure measuring 36m by 6m by6m high. One set bio-dries the wasteto reduce moisture content; the othercarries out bio-stabilisation to producea final residue suitable for fuelrecovery.

Process vapour is extracted via fourconcrete bio-filter chambers, castinsitu in strategic locations on thetunnel roofs. Chemical leachate isconveyed to a substantial concreteunderground tank, measuringapproximately 10m by 20m by 5mdeep.

The concrete for the tunnels, bio-filters and storage tank needed specialformulation to cope with the effectsof chemical leachate and condensateaggravated by temperaturespotentially as high as 85°C.

The presence of slot drains in thespigot floor slab of the compostingtunnels ruled out the use of a coatingto achieve chemical resistance, so thisneeded to be built into the concrete.Although the addition of microsilica tothe concrete would have providedsome of the required chemicalresistance, it would not havewaterproofed the structures.

Highly resistant to the corrosiveeffects of chemicals, PUDLO concretewaterproofing system was specifiedfor concrete in all of the critical areasof chemical exposure within the MBTplant. BBA approved, it promotes theintegral development of importantperformance characteristics inconcrete, including water- andchemical-resistance, without the needfor supplementary membranes orcoatings.

The bottom slab and kicker of theprocess tunnels were constructed innormal concrete. PUDLO wasincluded in the C40 concrete usedabove for the movement joint andspigot floor, as well as for the wallsand roof.

Royal Haskoning used a finite elementsoftware package to model thestructure in three dimensions with thetemperature gradients applied. Thisallowed them to calculate stressesdue to thermal effects, and to predictthe expansion and contraction of theconcrete to help design an effectivesolution.

BOARD OFAGRÉMENT

The altered microstructure of PUDLO

concrete, with its greatly reducedcapillary network, offered benefitshere, too. By minimising the ingress ofair/fluid, it is dimensionally very stableand tolerant of heat extremes, helpingto inhibit stress cracking.

Naturally increased strength gainsprovided when adding PUDLO to theconcrete without the need foradditional cement were anotheradvantage providing up to 30%additional compressive strength gain.

The type of mix used (DC-4m) had ahigh cement replacement content,around 66-80% ggbs. This slows downthe rate of strength gain especially inthe early age of the concrete.PUDLO test results at 7 days werewell above 30 MPa where figures ofaround 15 to 20 MPa would have beenexpected using the DC-4m mix with noadmixture. At 28 days, tests were upto 50-60 MPa for C40 concrete.

With replacement content as high as75%, the hydration process in

concrete will be slower, making earlystrike of falsework and formworkpotentially problematic. The use ofPUDLO in the concrete mix did notimpede striking of formwork andallowed tunnel formwork to be struckat the earliest opportunity helping withspeedy progression to follow-on works

Inspection played an important role inensuring PUDLO elements werecorrectly prepped, poured, compacted,cured and struck in line with qualityprocedures. Given the high operatingtemperatures within the tunnels,supervision of compaction wasparticularly important to ensurethorough removal of air bubbles.

PUDLO inspector, Helen Morgan, said:“The VolkerFitzpatrick team paid greatattention to quality and workmanship,following our guidance at every stageon the best practice for installingPUDLO concrete, such as making sureshuttering was properly insulated.”

A Case Of

Long-Term

Treatment

PUDLO still at work

under the harshest

conditions since 1938.

Maple Lodge Sewage

Treatment Works in

Hertfordshire has been in

operation since the 1930s. The

initial designs were proposed in

1933 to deal with London’s

growing sewerage disposal

problem. It was planned to

replace most of the existing

sewage disposal works and

pumping stations with trunk

sewers and a centralised

Sewage Treatment Works. The

design was finalised in 1937

and the new treatment plant

began construction in 1938.

In its day, Maple Lodge was the

largest and most complete

installation outside the United

States. The works is a fully nitrifying

diffused-air activated sludge plant

with heated anaerobic sludge

digestion. It was imperative that the

design encompassed products that

would withstand the harsh chemical

environment, maintain its watertight

integrity, and cope with a constant

wet-dry cycle.

The design incorporated the use of

PUDLO as it is the world's first

integral waterproofing additive for

use with concrete. PUDLO has been

in continuous use since Victorian

times for waterproofing both steel

reinforced, non-reinforced concrete,

water retaining and water resisting

structures.

The waterproofing characteristics of

PUDLO inhibit the major corrosion

mechanisms in concrete and as a

result increases structural durability.

PUDLO has an unmatched global

record of product performance in

service spanning over 130 years,

providing protection against water

ingress and corrosion, even in high

exposure class environments.

The construction of Maple Lodge

Sewage Treatment Works site was

seen as a triumph of mechanisation

with many innovative features. New

technology meant a single 26 acre

site replaced local disposal works

with an aggregate footprint of 500

acres. To this day, apart from the

updating of the plant and control

systems, the treatment process

initially employed at Maple Lodge

Sewage Treatment Works remains

essentially unchanged.

Primary treatment was through four

grit channels, each capable of

passing 22MG/d. After the grit

channels, sewage passed through

storm weirs, a measuring flume and

into the comminutors. The automatic

control of grit channels and

comminutors was seen as very

advanced in its day, as flow

increased additional channels or

comminutors were brought into

action, motorised pen stocks and the

comminutors’ motors were governed

by the sewage levels in the

measuring flume.

Sedimentation took place in 900,00G

tanks, sewage then entered one of

eight 750,000G aeration lanes.

Average aeration time was about 12

hours. Final settlement was

undertaken in 12, 250,000G tanks.

Home to Arsenal Football Club since2005, the 60,000-seat Emirates Stadiumset a tough engineering challenge withits imposing 27,000m2 roof andsubstantial trusses.

While not quite on the same scale,relocation of the local waste and recyclingcentre to make way for the £357 millionnew stadium at Ashburton Grove posedtechnical challenges, too. Opened in 2004, the three-storey £60mfacility provided a brand new, multi-purpose waste transfer and recycling hubfor the London borough of Islington andthe North London Waste Authority(NWLA). Run by the NWLA's waste contractor,London Waste Ltd, the centre in HornseyStreet has a 401,500 tonnes capacity andis licensed to process 275 tonnes ofwaste per hour. It was built to handle allhousehold waste from Islington as well asa proportion from neighbouring boroughs,Camden and Haringey, and has scope toprocess 50,000 tonnes a year ofrecyclable waste.Multi-functional

The multi-functional centreaccommodates a range of facilities overthree levels.The ground floor and inner basementhouse a transport depot for IslingtonCouncil with workshops, vehicle washarea, paint spray facility as well as carparking. The basement service yardincludes compactors receiving waste viachutes from the main waste hall above,as well as a weighbridge and containeddisposal of street cleansing debris.A control room, canteen and furtherweighbridge office are located on the firstfloor, alongside the main waste transferhall which is split into three distinct areas.The first is a large tipping apron with sixcompactor chutes for conventional,compactable waste, alongside tippingbays for other domestic waste. A secondarea accommodates tipping and bulking ofrecyclable waste, including glass, paper,cans and textiles as well as bulky items.The third is a segregated civic amenityand recycling areas for householders to

deposit materials and items they cannotrecycle through kerbside collection. With a large proportion of waste handlinglocated in the tipping hall on the first floor,the concrete slab faced toughperformance demands of exceptionalcharacteristics.The floor needed to withstand substantialwear and tear from heavy vehicles andplant as they tip and shovel waste, andoff-load and shunt laden skips andcontainers. The project team also requiredgood resistance not just to water but alsoto the chemical residues - mostly acidic -leached by the waste.Concern

The tipping hall presented three particularareas of concern, as Ian Flewitt, a partnerat the consulting engineers, Price &Myers, explains: “While no waste isloaded or stored directly on the floor ofthe tipping apron, we had to protectagainst spills which potentially mighthave chemical content from, forexample, car batteries.

PUDLO’s special

concrete formula

meets waste

facility challenge

Impact, abrasion and

chemical resistant, as

well as water

resistant, PUDLO-

modified concrete

floors mark 9 years of

problem-free service

at London borough

waste and recycling

centre.

“PUDLO were the only peoplewho came back with ideas for asolution.”Ian Flewitt, Price & Myers

“In the tipping area for glass, cardboardand other recyclable waste, the floor issubject to heavy loads, abrasion andimpact from plant scooping and movingmaterial between pens.

“The third area, the domestic wastetransfer centre, includes a deposit forbatteries, so again, there was thepossibility of the floor being exposed toacid residues. There is also a physicalelement with skips being loaded on andoff lorries, and scraping the floor asthey are pushed into place.”

As well as being engineered for use by alltypes of waste vehicle, including bulkarticulated vehicles, floor performancecriteria also needed to account for futureflexibility. The facility is designed toaccommodate different recyclable fractionsand recycling bays are moveable to adaptto future collection systems, incurringadditional wear and tear.Sound waterproofing of the first floor slabwas also essential to protect theworkshops, plant room and parking areasbelow from wash-down water used toclean the first floor slab.Ian Flewitt said: “PUDLO were the onlypeople who came back with ideas for asolution and who were keen to spendtime working on a mix that wouldprovide all the performancecharacteristics we required.”

He added: “They provided us with verygood upfront technical service indeveloping and refining a design for themix. This was followed by furtherservice support inspecting the mix, thebatching and attending site to overseethat it was placed correctly.”

Final mix

The final mix included fine steel fibres toimprove abrasion resistance, polypropylenereinforced fibres for impact resistance, andthe addition of a pozzolanic compound foracid resistance. These were carefullyformulated and tested to ensure theresulting gains added to the water-proofingperformance of the PUDLO additive.Since the application was unique andcharted new territory in terms of concreteadditive formulation, there were no setcriteria for performance. The project teamneeded to see as much gain as possible inthe characteristics required so that theycould confidently validate the engineeringand adopt the innovative mix.PUDLO carried out painstaking formulationand testing of the mix design at micro-structure level, looking at the potentialproblems of acid leachate penetration andarriving at a pozzolan content that wouldprovide effective defence. The sampledemonstrated high resilience to chemicalattack, proven by ensuring the free lime(calcium hydroxide) was physically boundand converted to calcium silicate.The use of fibres to create impactresistance is well-known, but enhancing

concrete to counter abrasion is far lesscommon.A sample of the special formula was castand evaluated for abrasion by assessingthe rate of loss of thickness subject to alaboratory scrape test (using Taberanalysis). Testing showed a three-foldincrease in abrasion resistance overordinary C40 concrete.Alternatives, such as a traditionalwaterproof mix with an applied powder ontop as used for warehouse floors, wouldnot have addressed all of the performanceissues as neatly as the PUDLO solution.

“There was a limit on headroom,”points out Ian Flewitt. “So it was anadvantage to incorporate the water-proofing and other protective propertiesinto the structural slab. A conventionalslab with screeded protection on topwould have involved extra costs andtime, and a build-up of finished levelthat would have lost us headroom.”

World famous

The application was also a first in PUDLO’s130 years history. The world-famousadditive has risen to challenges of water-proofing and durability in environments asextreme as the Middle East, andstructures as high profile as the RoyalAlbert Hall and the 2012 Olympicvelodrome. Islington’s waste transferproject provided a new landmark inPUDLO’s evolution, pushing the envelopeof its chemistry to bolt-on new andunprecedented performance attributes. In 9 years of operation, the floors arestanding the test of time and meeting allexpectations. Ian Flewitt comments: “The concretefloors are performing well, and there isno evidence of any serious abrasion orany evolving problems.”

Among other things, the technical successof the design has done much to reassurethe local community who had beenconcerned about how well the slab andmulti-storey design would work in whatwas a progressive solution not seenbefore.The project underlines how resourcefuldesign, which is bold enough to push theenvelope of materials engineering, canovercome tough construction and planningconstraints in urban redevelopment.

IN GOOD COMPANY

PUDLO: Waterproof, Durable Concrete

Christopher Stanley, Technical Director of Unibeton Readymix said: “Unibeton is the largest producer of concrete in the Middle East. Our reputation depends very much on the quality of concrete we supply. Pudlo is without a doubt the best and most reliable concrete waterproofer in the market place, and we always recommend its use to our clients for waterproof concrete work. Its high quality and reliability is the reason why it has now been in use for more than a hundred years, and none of the many other available waterproofing products that we have tested can in any way match its performance. “

“A PUDLO inspector attended both the preparation phase, concrete pours and post-pour curing operations to make sure they were carried out in line with its on-site quality system,” says Conor Hanlon of McGee Construction. “It also offered us technical assistance when details needed reworking to suit in-situ conditions. Incorporating waterproofing in the concrete eliminated the labour, logistical complexities and health and safety challenges of installing sheeting,”. Project: Newcastle INTO Building

John Doyle Construction’s Technical Director, Peter Goring says: “Very close attention is always given to the construction materials in use and the test procedures that prove their reliability and performance. But when you are working on a national monument like the Royal Albert Hall the sense of responsibility becomes more acute. We were also assured by the presence of the PUDLO site inspectors during and after installation.” Project: Royal Albert Hall

Ian Flewitt of Price Myers said: “PUDLO were the only people who came back with ideas for a solution and who were keen to spend time working on a mix that would provide all the performance characteristics we required.” He added: “They provided us with very good upfront technical service in developing and refining a design for the mix. This was followed by further service support inspecting the mix, the batching and attending site to oversee that it was placed correctly.” Project: Arsenal Waste Transfer Station
