MiraCLAY 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 patented Infrabond procedure that locks the sodium bentonite into place 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 MiraCLAY waterproofing membrane has the ability to heal itself 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) Has the ability to expand and seal cracks in concrete
