BELOW GRADE WATERPROOFING

Protecting the Investment in your Building

Prevent water and moisture problems with a complete below-grade concrete waterproofing system.

Major investments are made in buildings today, and those investments deserve the very best protection available. For that protection, look to the only company that has consistently helped owners protect their buildings against the ingress of moisture for over 95 years: W. R. MEADOWS. Recognized as the leader in developing and producing quality products for the construction industry, W. R. MEADOWS’ products can bring to your project a coveted reputation earned with architects, engineers and contractors.

What makes up the total moisture control package?

Moisture is found in some form or another on every building site. The difference between a satisfied owner and a “problem” project is how you deal with that moisture. Critical to below-grade waterproofing are all the products used in combination to create a system. It’s this system that ensures that you have complete control of moisture migration in a facility. With W. R. MEADOWS’ complete line of waterproofing and moisture control products, you’ll have all the products needed to create and install the proper protective system for your building.

New Product: HYDRALASTIC 836 SL Below-Grade Waterproofing Membrane

HYDRALASTIC 836 SL is a single-component, cold-applied, solvent-free, water-activated, below-grade waterproofing system. It does not shrink and has a low VOC content. It will not crack in extreme cold or flow due to softening at high temperatures. HYDRALASTIC 836 SL is suitable for use on interior or exterior concrete surfaces, where protection from water intrusion is desired. The product can be used for both above-grade and below-grade applications. HYDRALASTIC 836 SL is excellent for many applications, such as waterproofing plaza decks and elevated composite decks and also in between-slab (split-slab) applications.

BELOW-GRADE CONCRETE WATERPROOFING PRODUCTS AND ACCESSORIES

HRM 714

hot-applied rubberized asphalt waterproofing membrane is a 100% solids blend of asphalts, synthetic rubber polymers, and filler formulated to provide toughness with flexibility and low moisture vapor permeance.

HYDRALASTIC 836

is a cold-applied, solvent-free, single-component below-grade concrete waterproofing compound. It does not shrink, has a low volatile organic compound (VOC) content, and has a very low odor. It will not crack in extreme cold, or slump due to softening at high temperatures. HYDRALASTIC 836 is excellent for horizontal and vertical applications such as waterproofing plaza decks, planter boxes, and sealing parapets.

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.

PRECON LOW TEMP

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 LOW TEMP and the concrete cures, a mechanical bond forms that secures the concrete to the membrane. This low temperature version can be installed in temperatures down to 25° F (-4° C).

MEL-DEK

below-grade waterproofing system provides an excellent waterproofing membrane for bridges, parking decks or other vehicular traffic structures to be overlaid with an asphaltic concrete wearing course. It is ideal for repair, maintenance or new construction applications.

MEL-ROL LM

is a single-component, polymer-modified, cold-applied, water-based, liquid waterproofing membrane ideal for below-grade horizontal seamless waterproofing applications. It uses the same high quality rubber polymers found in W.R. MEADOWS’ popular MEL-ROL “peel and stick” membrane, and converts them into a heavy bodied, high solids, quick-drying liquid membrane.

MEL-ROL

waterproofing system is a flexible, versatile, dependable, roll-type below-grade waterproofing membrane. It is composed of a nominally 56 mil thick layer of polymeric waterproofing membrane on a heavy-duty, 4 mil thick, cross-laminated polyethylene carrier film.
