SEPTA (Southeastern Pennsylvania Transportation Authority) had several settlement issues on two rail lines at a road crossing in Ambler, Pennsylvania. The 14” thick concrete slabs supporting the track had settled in areas as much as 1-7/8”.
Quality Concrete used the PolyLEVEL Polyurethane Injection System to resolve the problem. PolyLEVEL is a two-part urethane that, when combined, expands into a waterproof, rigid foam that is used to fill voids, stabilize slabs, and lift concrete. The installation of PolyLEVEL began by drilling penny-sized injection holes into the concrete slab. Next, using specialized equipment, approximately 500 hundred pounds of PolyLEVEL was injected below the slab through 96 injection areas. The concrete was then lifted back to its original position.

Quality Concrete was able to lift these sunken and settled concrete slabs in Plainsboro, New Jersey with the use of the PolyLEVEL Polyurethane Injection System. Before the use of PolyLEVEL, the slab had sunken close to 2 inches. The PolyLEVEL system was installed in less than one day, and was immediately able to be walked on just a few moments after installation. The slab was successfully raised back to its original elevation.
