Push Piers vs. Helical

The Challenge:

•Building settlement up to 8”

•Slab failure

•Unusual soil conditions

Soil Reports:

• Hydraulic piers on the perimeter

• Helical piers on the interior

Remediation Of A Post Tensioned Edge Heaved Structure

Post Tension Lowering

The Challenge:

• Expansive soils and water intrusion combined to raise the edge of the house on 2 sides.

• The lack of an edge turndown localized the heaving to the sides of the structure.

Manometer Survey Results

• Note the areas of high readings on the east and south sides.

• The total elevation difference is approximately 2 ¾”

• The areas are localized to with in 5-8 feet of the perimeter.

Interior Damage

The Solution:

1. Install helical piers on the perimeter of the areas that are affected with out raising.

2. Excavate the soil under the raised area leaving an intentional void.

3. Lower the house to the desired elevation4. Secure the helical piers.5. Grout in selected areas.6. Optional cut off wall built around the

perimeter.

Service Plan

• Note the interior piers at the load bearing interior column footing.

Additional Capacity Retrofit

The Challenge:

• Water tank capacity not designed into the slab.

• Tank Capacity 140,000lbs• 12” Thick Slab• Undermined • Reinforcing found at the bottom of the

slab

The Solution:

• Seven [7] - 20kp piers installed through slab

• 7*20 = 140kp

Saving Time and Money

The Challenge:

• Differential settlement in slab

• Equipment pad settlement

• Masonry wall settlement

• Concrete Replacement– Architectural finish

– Delivery dock downtime

The Solution:

• Mud jack the slab

• Stitch the cracks

• Helical anchors– Equipment pads

– Masonry walls

DESCRIPTION: PRICEReplace concrete & block per plan. Dowel & match colors as close as possibleInstall 2 helical piers. (Includes 25 yr warrantee)

Includes HVAC tech & machinery shimming as needed.Includes waterproofing in planters and replacement of landscape as needed. 62,451.23$

Alternate1: Mud jack, Grind, and Stitch crack at the east end of Area 2 with (3,499.00)$ Roadmender Polyurethane.

Alternate 2: Mud jack sunken sidewalks in area 2 outside (3,251.00)$ Alternate 3: Mud jack sunken sidewalk and paving in Area 3 (4,862.00)$ Alternate 4: Install 20 helicals in equipment room instead of replacement

and dowels of surrounding concrete. (25 yr Warrantee) (2,150.00)$ Alternate 5: Install 3 helicals and raise existing sunken block walls

in area 3. (25 yr Warrantee) (2,696.00)$

All cars parked near the w ork w ill need to be moved ahead of time or be tow ed by management.We cannot be responsible for damage to existing infrastructure (i.e. plumbing, phone), not installed to at least 24" below grade.Removals assume existing concrete is 4" thick. w ith no reinforcing. If thicker concrete is discovered, then prices w ill need to be adjusted.Job is bid to be completed in one job mobilization additional mobilizations w ill be charged to recover additional cost.All irrigation modifications and repairs by others. Price includes clean up and haul off.

Basement Addition

The Challenge:

• Homeowner wanted a basement– Excavation near structure would be

needed

• Possible movement in foundation, support would be needed

The Challenge:

• Soils in the Area of Influence Would Effect the Foundation

Let’s Talk About Concrete

Negative Side Concrete Waterproofing

The 2 Types of Concrete

That which HAS cracked

AND

That which WILL crack

The Inherent Nature of Concrete

Water leaving concrete as it cures leaves behind capillaries

Capillaries are filled by water after the curing is complete resulting in internal stresses

The “Life Cycle” of Concrete

SteelCorrosion

CrackingStructural Deterioration

Extensive Repair

Expansion Stress

Water Penetration

Reasons For Waterproofing

• Leak Prevention

• Corrosion Resistance

• Aesthetics

How Does Krystol Work ?• Krystol works to further react the

unhydrated cement particles in concrete thereby improving the natural hydration process of concrete.

• Krystol simultaneously fills the remaining pores and capillaries with millions of hair-like crystals resulting in impermeable concrete.

• The Krystol reaction will penetrate throughout the concrete mass wherever moisture is present and does not shrink in the absence of moisture.

Slurry Application

Cracking & Self Sealing

Concrete block was struck with a hammer to intentionally crack block.

Cracking & Self Sealing

After 7 days leak is being healed

Cracking & Self Sealing

Leakage was stopped completely by the formation of crystals within two weeks.

Below Grade Pits at Ocean Construction

• KRYSTOL T1 and KRYSTOL T2 were used to waterproof this below grade pit against significant hydrostatic water pressure in 1975. The equipment room is located at the edge of the Fraser river, 17-feet below the water table.

“Almost 30 years ago we used the Krystol Waterproofing Treatment to stop substantial leaking in our concrete pits. They are still dusty dry today and we have been happy customers ever since.” Ron Boyes, Superintendent, Ocean Construction Ltd.

Krystol Specification #1

Mud-jacking

Mud-jacking

• A pattern of 1-58”holes is drilled through out the sunken slab

Mud-jacking

• Grout is pumped under the slab, once void is filled the grout pressurizes and raises the slab to the desired height

Mud-jacking

• The holes are then patched with cement
