Precon Goes Where Conventional Waterproofing Doesn’t

W. R. MEADOWS presents PRECON, a blindside and underslab membrane that offers both waterproofing and vaporproofing protection. Not only does the product block water, but it also inhibits vapor intrusion, creating an environmentally friendly indoor environment. Its dual functions make it a great fit for all waterproofing and vaporproofing needs.

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. It 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).

“PRECON reduces methane and radon gas intrusion, creates a barrier against termites, helps prevent moisture migration into structures, and provides a waterproof seal between membrane and poured concrete,” notes Matthew Price, president of W. R. Meadows, Inc.

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’s fabric bonds tenaciously to poured concrete walls to create solid waterproofing protection. Superior to traditional clay-type products, PRECON features a greater seal to stop water in its tracks. We also have a low temperature version available.
