PolyLEVEL™ Stabilization
Challenge
A homeowner in Westlake Village, Ca, who's home is built near a lake canal, was noticing some signs of settlement. The homeowner knew something had to be done to stop the settlement. Settlement like this is most commonly due to the shifting in the soils underneath the foundations footing. The homeowner contracted Saber Geotechnical Construction Solutions to stabilize the home, from future settlement.
Solution
Saber Geotechnical Construction Solutions proposed to stabilize the home using the PolyLEVEL system. PolyLEVEL™ is a two-part urethane that when combined expands into a rigid foam used to fill voids, stabilize slabs and lift concrete. Once injected through small 5/8 inch drilled holes in the surface or slabs, a chemical reaction converts the liquid urethane components into a strong, rapidly setting, waterproof foam material. In it’s foam state, PolyLEVEL™ is light weight, weighing two to six pounds per cubic-foot (pcf). Opposed to mud-jacking which can weigh upwards of 120 pcf, thus adding a significant burden to the supporting soils under the slab, and potentially contributing to further settlement issues. With a compressive strength of 10,800 pounds per square foot, PolyLEVEL™ has the strength to support the most demanding residential loads. For this job Saber used the polyurethane injection to stabilize the property, and to prevent any future settling. Although, there was no lifting or leveling of the property there is a warranty included.
