Photo Album: Apartment Foundation Repair in Agoura Hills, CA - Phase I

Saber Geotechnical Construction Solutions proposed to stabilize this apartment complex using the Helical Piers and 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 will use the polyurethane injection as a void fill once the helical pier system has been installed and the structure has been lifted in order to prevent any future settling.
