CCW MiraCLAY EF Waterproofing Membrane 5' x 14' Roll

CCW MiraCLAY EF has a uniform layer of sodium bentonite clay that is sandwiched between a durable puncture-resistant nonwoven polypropylene fabric and a high-tensile strength woven polypropylene fabric and then needle punched together with thousands of high-strength denier yarns. These fibers are then thermally fused to the polypropylene in a proprietary Infrabond procedure that locks the sodium bentonite into place.

• MiraCLAY EF is used where groundwater is contaminated with either salt, chemicals or other foreign substances, as determined by a site water analysis, which can keep CCW MiraCLAY from hydrating
• MiraCLAY EF waterproofing membrane has the ability to heal itself if ripped or punctured.
• In a hydrated state, bentonite clay has tremendous impermeability and excellent resistance to chemicals (i.e., acids, bases and hydrocarbons).
• MiraCLAY EF has the ability to expand and seal minor cracks in concrete up to 1/16" in width.

Applications

MiraCLAY EF is designed for waterproofing below-grade structural slabs as well as construction methods incorporating lagging, concrete caisson or shotcrete retention walls. MiraCLAY EF is also very effective in rehab waterproofi ng and zero clearance property line construction.
