W.R. Meadows Precon

SKU: M15118050

PRECON is a composite sheet membrane comprised of a non-woven fabric, elastomeric membrane, and W. R. MEADOWS exclusive, patented plasmatic core (U.S. Patent No. 7,179,761). The plasmatic core is a seven-layer matrix designed for toughness and provides the lowest water vapor transmission (WVT) rating on the market. Once concrete is poured against PRECON and the concrete cures, a mechanical bond forms that secures the concrete to the membrane.

PRECON 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.
