What is PRECON PRECON is a composite sheet membrane comprised of a non-woven fabric, elastomeric membrane that is used for waterproofing vertically and horizontally. 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. Uses 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/blindside waterproofing and vaporproofing.…
