The BriarGlen II Condominium Association was experiencing sunken slabs near a condo entrance up to about 1 inch. With the use of the PolyLEVEL System Quality 1st Contracting was able to lift the sunken and settled slab. The process took less than an hour, with absolutely no mud jacking involved. Penny sized holes were drilled into the sunken slab and with the specialized PolyLEVEL equipment the polyurethane injection lifted the concrete slab.
