Concrete Slab Curling

Curling is one of the most common defects found in a structure's floors. Slabs curl upward at joints, saw-cuts and edges. As forklifts pass over the joint, this loss of subgrade support causes slab movement. 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 floor deterioration.
