Curling is one of the most common defects found in floors, especially those in warehouses. Slabs curl upward at joints, saw-cuts and edges. This loss of sub grade support causes slab movement as forklifts pass over the joint. Joint edges deteriorate, cracks in the slab develop and wires embedded in concrete for automatic guidance systems may break. The amount of differential movement from one side of the joint to the other is directly related to the speed of warehouse floor deterioration.

Repairs to broken and deteriorated concrete slabs are often put off for fear of causing major traffic delays or business disruptions. Rapid setting concrete offers a unique time sensitive solution for concrete problems that must be repaired in hours, not days.

Pavement and slab settlement problems are common to highways, bridge approaches, taxiways/runways and factory floors. Many settlement problems are caused by weak underlying soils.
