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 100 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 system?
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 concrete 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: HYDROWRAP PUMA FLASHING – Flashing and Detailing Membrane System
HYDROWRAP PUMA FLASHING is a fast-curing liquid membrane designed for flashing and detail work on concrete, wood, or metal. Built on advanced PUMA (polyurethane-methacrylate) technology, it cures quickly—even in cold weather—and doesn’t require fabric reinforcement. It’s used to help protect vulnerable areas like wall intersections, cracks, and penetrations from water intrusion, and is compatible with a wide range of W. R. MEADOWS waterproofing systems. HYDROWRAP PUMA FLASHING goes down fast, is traffic-ready in about an hour, and contains zero VOCs, making it a clean option for both jobsite productivity and environmental compliance.
Whether you’re working on decks, rooftops, or tie-in joints, this detailing membrane is built for durability, flexibility, and speed—especially in time-sensitive or cold-weather applications.

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 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.
MEADOW-PRUF CO-SPRAY
is a liquid-applied, waterproofing membrane ideal for below grade vertical waterproofing applications. MEADOW-PRUF CO-SPRAY cures to form a tough, seamless, elastomeric membrane, which exhibits excellent resistance to water and water vapor. MEADOW-PRUF CO-SPRAY is modified with a blend of synthetic polymers and special additives. The product is applied using a co-spray system (in combination with W. R. MEADOWS CURE-IT co-spray curative).
MEL-DEK
concrete 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 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.
