Abstract
The present invention is a wet cure concrete cover which is designed and configured to retain moisture during the process of curing concrete. The blanket is a multi-layered structure having a base layer, for contacting the cement, and a film layer is extrusion coated to the base layer for protecting the base layer. The base layer is a non-woven, hydrophobic material that will allow the water to adhere to its fibers. In one embodiment a film layer, preferably polypropylene, is extruded onto the base layer. In a second embodiment a low-density polymerize resin is secured to the base layer via a tie layer. Alternatively, under conditions of high temperature and lower humidity, the film layer of the first and second embodiments can include a plurality of perforations, allowing for periodic water spraying or rewetting of the curing cover.
