TREMDrain NW is a two-layer drainage mat made of a polystyrene core and needle-punched nonwoven polypropylene fabric
TREMDrain NW is a cost-effective solution for single-sided subsurface drainage applications that need a standard non-woven filter fabric bonded to a formed core with low compressive strength and moderate flow capacity. The TREMDrain is used in conjunction with TREMproof and Paraseal waterproofing membranes as a protective course as well as a substitute for typical pipe and stone drainage systems. TREMDrain NW is best suited for vertical walls no taller than 20 feet. The REM Drain Series Drainage and Protection Boards can be used in place of or in addition to a separate protection course.
The TREMDrain Series of mats are used with TREMproof� and Paraseal� waterproofing membranes serving both as a protection course and replacement for traditional pipe and stone drainage systems.
