What It Does:
The slab pier system can stabilize and restore concrete slabs damaged by settlement. The pier consists of interlocking tubular steel sections. An adjustable bracket connects the top of the pier to the underside of the slab.
- Year-Round Installation
- Designed With Galvanized Steel for Corrosion Resistance
- Deep Pier Installation Extends Beyond Unsuitable Soils
- Non-Disruptive Installation
- Creates Opportunity To Lift Slab and Partition Walls Back To Level Position
- Life-of-Structure Manufacturer’s Warranty
Slab piers are designed to be driven deep into the earth, bypassing soil that is ill-suited to support weight, so that your floor can be supported by strong, competent earth. Slab piers also provide an opportunity to lift your concrete slab back to its original position, often closing cracks and eliminating tripping hazards.
How Slab Pier Systems Work
There are two types of slab piers: push-type slab piers and helical slab piers. Both foundation repair products can be effective, and selecting one over the other depends on your unique situation and the preferences of the contractor who is installing them. Both types of slab piers use small, accessible installation equipment, so installations can be completed in tight-access areas such as bathrooms or laundry rooms.
The process for installing hydraulically-driven slab piers and helical slab piers is very similar. In both cases, the first step is to expose the soil at each pier location by drilling holes through the concrete slab.
If installing hydraulically-driven slab piers, a slab bracket is positioned in the hole so that the flanges on the bracket extend to support the underside of the slab. With the bracket in place, steel pier sections are hydraulically driven through the bracket until the pier contacts competent soils.
If installing helical slab piers, the pier shaft is rotated while downward pressure is applied. The helical blades on the pier’s shaft advance the pier into the soil and also provide anchoring strength once competent soil is reached below. A slab bracket is positioned around the pier and beneath the concrete slab after the pier reaches its proper depth.
For both foundation pier systems, the next step is to transfer the weight of the concrete slab through the piers to deep, stable soil below. A lift can then be attempted to bring the slab and interior partition walls back to their original position.
PolyLevel is then carefully pumped at a low pressure under the slab to fill any voids that may have been created by the soil settlement and slab-lifting process. Finally, holes at pier locations are filled with concrete, leaving the floor permanently stabilized against future settlement in its new position.
When To Use Slab Piers
You should use slab piers in all cases except when either the floor slab is extremely thin or the cracking is extensive. The chart below outlines the advantages and disadvantages of each type of concrete slab floor repair:
