Concrete curling is a phenomenon that can greatly disrupt serviceability of a concrete floor. Concrete is subject to warping at the edges from uneven drying or differences in temperature. The curling action can lift the edges of the slab upward, creating an unsupported section at the edges. Factors that lead to curling include:
Uneven drying at surfaces
Poor concrete mix
Water content ratio to high
Improper subbase preparation
Foam Injections: EFT provides minimally invasive techniques for repairing curled concrete floor slabs. Polyurethane foam is an ideal technology for projects where existing businesses occupy the warehouse area.
The repair process is commonly referred to as joint stabilization. In general, the process starts with filling the subfloor void space with polyurethane. It is preferable to inject a fast-setting material for this task. Once the base has been stabilized, the surface flatness can be addressed if required. In most cases, the work can be performed with minimal impact to the facility and it's operations.
