Internal Slab Supports
What are Internal Slab Supports?
An Internal Slab Support is a Helical Pier which is designed to re-level and support your interior floor slab. They are typically installed every five foot on center throughout the areas which need lift and support. Floor slabs can be leveled and stabilized without the mess and inconvenience of replacing the entire slab.
Internal Slab Supports for foundation and sinkhole repair are hydraulically torque driven through a cored small hole in your foundation. This allows the area of your homes slab, which has been damaged by settlement, sinkhole, or poor soil conditions to be slowly and gently raised back to level. This process is more permanent than pressure or chemical grouting and more cost effective.
Internal Slab Supports are designed to be driven into deeper soils beneath your home, bypassing soils which have shrank or migrated, so that, your interior slab can be supported by strong, competent load bearing strata. Slab piers also provide an opportunity to lift your concrete slab back to its original position, often closing cracks and eliminating tripping hazards.
First, the Geotechnical Engineer’s repair design is reviewed and installation points are located around the property. Plastic sheeting is taped to the walls and the baseboards in the room where the Internal Slab Jacks are to be installed. Small holes are cored through the foundation to gain access for the supports. The Helical lead section is driven down into the soil past the weak zone. Additional Helical extensions are driven to the depths needed to generate a 2:1 safety factor. Then, excess pipe is cut off and the bracket is placed underneath the slab. An adjustable bracket connects the top of the pier to the underside of the slab for easy lifting and re-leveling of the concrete slab. The bracket assembly is tightened and pressure is applied; the bracket evenly distributes lifting force along the bottom side of the concrete slab. The slab is lifted back to as close to original grade as possible. The core hole is backfilled with concrete and trowel finished. The work site is cleaned up.
