W.R. Meadows Precon Low-Temp

SKU: M15118051

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).


  • Provides a waterproof seal between the membrane and poured concrete wall.
  • Helps prevent moisture migration into the structure.
  • Acts as a barrier against termites.
  • Reduces methane and radon gas intrusion.
