Precon Low-Temp is a composite sheet membrane comprised of a non-woven fabric, elastomeric membrane, and WR Meadows’ exclusive, patented plasmatic core. The plasmatic core is a seven-layer matrix designed for toughness and provides the lowest water vapour transmission (WVT) rating on the market. Once the concrete is poured against Precon Low-Temp and the concrete cures, a mechanical bond forms that secures the concrete to the membrane.
Precon Low-Temp is used as a blindside membrane in vertical applications where access to the positive side is limited. The membrane can also be used for horizontal applications for underslab waterproofing and vaporproofing. This low-temperature version can be installed in temperatures down to 25° F (-4° C).
