This new distribution warehouse was plagued by severe deterioration and ride-ability problems caused by slab curl shortly after construction. This loss of sub grade support at construction and control joints caused differential slab movement as forklifts passed over the area.
Sub grade support was restored by pumping a cement and fly ash grout in under low pressure to fill the voids and stabilize the slab. Surface repairs included grinding the surface to improve ride-ability, partial depth removal/replacement of the distressed concrete, and installation of new joint sealant.
