Waterproofing Membrane & Dampproofing
W.R. Meadows Mel-Rol®
Rolled, Self-Adhering Waterproofing 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, four-mil thick, cross-laminated polyethylene carrier film. A handy overlap guideline is printed 2 ½” (63.5 mm) in from the material edge on each side to assure proper overlap coverage and to assist in maintaining a straight application. Special exposed polymeric membrane strips are provided on both sides for positive membrane-to-membrane adhesion in the overlap area. The membrane strips are protected by a pull-off release strip.
W.R. Meadows Mel-Rol® LM
Single-Component, Water-Based, Polymer-Modified, Cold-Applied, Waterproofing Membrane
Mel-Rol LM is a single-component, polymer-modified, cold-applied, water-based, liquid waterproofing membrane ideal for below-grade horizontal and vertical seamless waterproofing applications. We have taken the same high quality rubber polymers found in Meadow’s successful Mel-Rol “peel and stick” membrane, and converted them into a heavy-bodied, high-solids, quick drying liquid membrane.
W.R. Meadows Mel-Drain
Rolled Matrix Drainage System
Mel-Drain is a dimple-raised, molded polystyrene sheet bonded to high strength polypropylene fabric. This geocomposite allows the passage of moisture through the fabric while preventing fine soils from entering the drainage channel. Various drain designs are available, depending on soil pressure and flow specifications.
W.R. Meadows Pointing Mastic
Cold-Applied, Single-Component Polymeric Sealing Compound
Pointing Mastic is a pre-mixed, cold-applied, polymeric single component sealing compound. Pointing Mastic was specifically designed to seal all exterior, vertical and horizontal terminations of Mel-Rol®, Mel-Dek™, Air-Shield™ and PMPC® from W.R. Meadows. It is also used for adhesive bonding of Protection Course and Mel-Drain™. Pointing Mastic can be used on all patches and overlaps in detail areas. It offers excellent cohesive and adhesive qualities when applied to structural concrete, masonry and/or wood. Once applied, it provides excellent adhesive and bonding strengths. Pointing Mastic cures to form a tough, flexible membrane and is designed to meet a variety of building/construction product applications. These uses include sealing terminations for vertical or horizontal vapor proofing or waterproofing membranes, deck waterproofing systems, air barriers and flashing membranes.
W.R. Meadows Sealmastic™
Sealmastic emulsion-type Damproofing is a breather-type which permits moisture vapor to escape through the film, while remaining resistant to water penetration. This prevents blistering of applied films. The product can be applied to green concrete.
- TYPE I (spray-grade) is an asphalt-based, non-fibered, clay emulsion. Under normal use, it resists flow or sag. Its greater resistance to water is ideal where spray application is desired.
- TYPE II (brush-on/spray-grade) is an asphalt-based, clay emulsion with fibers specifically formulated to offer a tight film that combines both.
- TYPE III (trowel-on grade) is a trowel-applied mineral colloid, asphalt emulsion, fibrated with selected fibers and produced in an ideal, light trowel application consistency. TYPE III offers high weather, water, corrosion, and abrasion resistance. It can be used as an adhesive on foam board installations.
