Curling in concrete slabs (Nat)

The upward or downward movement of a concrete slab’s corners or edges due to moisture and/or temperature differentials within the concrete is known as ‘curling’ or ‘warping’. It may be evident in concrete elements other than slabs, such as wall panels. Curling typically occurs some months after concrete placement but can occur much earlier. The extent of movement is usually minimal, but may in severe cases be as much as 20–25 mm.
