CCW MiraCLAY Bentonite Clay Waterproofing Membrane features a layer of sodium bentonite clay sandwiched between a puncture-resistant, nonwoven polypropylene fabric and a high-tensile strength woven polypropylene fabric, then needle-punched together with durable denier yarns. These fibers are then thermally fused to the polypropylene in a proprietary Infrabond™ technique, locking the sodium bentonite into place.

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

Features

• Self-healing if ripped or punctured
• In a hydrated state, the bentonite clay has tremendous impermeability and excellent resistance to chemicals (i.e., acids, bases and hydrocarbons)
• Expands and seals cracks in concrete up to 1⁄16" in width
