SOPRADRAIN™ 104 is a versatile workhorse that delivers first-rate protection for waterproofing systems. Faced with a non-woven fabric layer, this high-density drainage panel filters out dirt and sand particles to provide free-flowing drainage. Controlling the flow of hydrostatic water pressure creates dryer, lighter soil loads reducing stress on walls, floors, and waterproofing membranes. Engineered for heavy-duty applications, SOPRADRAIN™ 104 can serve as a drainage layer for parking decks, split slabs, and plaza decks.
