Polyurethane Foam Used To Raise Sinking Slab
Challenge
Stonehurst Association located in Freehold, NJ contacted Quality 1st Contracting to lift and level several sinking concrete slabs in the community. Our Account Executive, Jessica Long went out to meet with the property manager and discuss the causes of concrete settlement and the solution that would not only be most cost effective but also be a permanent solution. She explained that the problem was not the slabs themselves but the soil underneath. When the soil becomes too dry, too wet or is poorly compacted, it becomes weak and can no longer old the weight of the slab causing it to sink. A void is then created between the soil and the slab.
Solution
Jessica did a full walk through of the property, marked all the sinking slabs to alert homeowners of the trip hazards and provided the Association with a solution they could not turn down. She recommended PolyLevel, a State-Of-The- Art product that fills the void underneath the slab while raising and permanently stabilizing it. Our PolyLevel team drills small holes into each sinking concrete slab. Using special equipment, PolyLevel is injected below the slab to fill the void. When the void is filled the PolyLevel begins to expand raising the slab back towards its original position. When the slab is leveled the PolyLevel then begins to dry for permanent stability. Within just 15 minutes of completion, any slab could be walked on or driven over. The installation causes no disruption to the surrounding areas of the slab and also allows for a quick and easy clean up.
