Quikrete Structural Concrete Repair is a polymer modified, shrinkage-compensated, rapid setting, high strength repair material designed to make horizontal, vertical, and overhead structural repairs to any concrete surface. The material can be expanded with up to 10 Lb. (4.5 Kg.) of gravel and can be used for partial-depth repairs. Polymer Modified Structural Repair can be sculpted to match the contour or existing concrete surfaces.
