COREFLEX is composed of a thermoplastic membrane bonded with a proprietary Active Polymer Core layer. COREFLEX's fully welded seams provide complete waterproofing protection and is designed to resist high hydrostatic pressure and groundwater contaminants typically found surrounding foundations. 

This product has the ability to serve as both a water and gas barrier, and uses both a conventional weld and an overlap assembly to ensure water tightness. This construction provides enhanced seam performance and reduces the reliance of integrity on installation labor. COREFLEX is a membrane that may be applied either before or after the concrete pour.
