Abstract
An improved concrete curing blanket of light weight, high water retention and wicking action, and connectable into coverage of large concrete surface. The blanket has a surface layer (e.g. three mils) of low density polyethylene carrying any pigments that is heat sealed as a melted coating upon a batting layer (e.g. one-tenth inch) of a porous and resilient, non-woven, synthetic needle-punched fabric. Adjacent pieces of the blanket are heat sealed together to cover large areas of curing concrete. The batting layer conforms to the irregularities of the concrete surface to promote wetting action and enhance the curing function.
