MEL-ROL waterproofing system is a flexible, versatile, dependable, bituminous, 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. The two components are laminated together under strict quality-controlled production procedures.
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. All components of the MEL-ROL waterproofing system work together to provide a cost-effective, positive waterproofing system that’s quick and easy to apply.
MEL-ROL waterproofing system provides a cost-effective answer to properly waterproof foundations, vertical walls, and below-grade floors in residential and commercial construction. It is equally effective for use as between-the-slab waterproofing on plaza decks, parking decks, and structural slabs. Use it as a waterproofing membrane to isolate mechanical and electronic rooms, laboratories, kitchens, and bathrooms. MEL-ROL offers positive protection when “wrapped around” major rapid transit, vehicular, utility, and pedestrian tunnel projects. MEL-ROL can also be used on insulated concrete forms (ICF).
Installation of PROTECTION COURSE from W. R. MEADOWS is recommended before backfilling. MEL-ROL can also be used with drainage boards when specified.
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, PRECON, MEL-DEK, AIR-SHIELD, PERMINATOR, and PREMOULDED MEMBRANE VAPOR SEAL WITH PLASMATIC CORE 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.
POINTING MASTIC is designed to meet a variety of building/construction product applications. These uses include sealing terminations for vertical or horizontal vaporproofing or waterproofing membranes, deck waterproofing systems, air barriers, and flashing membranes.
It is used for adhesive bonding of protection course boards and rolled matrix draining systems. POINTING MASTIC is also applied between membrane and clamping rings at all terminations, drains, and protrusions. In addition, POINTING MASTIC is ideal for sealing joints and concrete curbs and gutters. The product can also be used with sewer joints.
POINTING MASTIC can be applied to seal top edge horizontal terminations as well as the inside and outside corners of overlapping detail strips.
FIBRE EXPANSION JOINT is composed of cellular fibers securely bonded together and uniformly saturated with asphalt to assure longevity. Wherever a cost-effective joint filler is required, FIBRE EXPANSION JOINT meets the need. Manufactured and marketed by W. R. Meadows since the early 1930s, FIBRE EXPANSION JOINT is backed by over 80 years of proven application experience. FIBRE EXPANSION JOINT is versatile, resilient, flexible and non-extruding. When compressed to half of its original thickness, it will recover to a minimum of 70% of its original thickness. FIBRE EXPANSION JOINT will not deform, twist, or break with normal on-the-job handling.
FIBRE EXPANSION JOINT is ideal for use on highways, streets, airport runways, sidewalks, driveways, flatwork, and scores of commercial and industrial applications subject to pedestrian and vehicular traffic.
SNAP-CAP provides a time- and cost-saving method for forming straight, uniform, and debris-free joints of the proper configuration, ready to seal. The top of SNAP-CAP pulls free and can be discarded. The exposed concrete surfaces assure balanced adherence to the sides. It is ideal for both horizontal and vertical concrete projects.
SPEED-E-JOINT consists of two solid pieces that have been pre-assembled for easy handling and installation.
SPEED-E-JOINT offers an ideal solution to controlling cracks in concrete. It is a rigid preformed contraction joint that produces a straight-line crack on the surface of concrete slabs and locks into the aggregate just below the surface. SPEED-E-JOINT is strong, economical, and eliminates waste in providing straight lines. It is quick and easy to install.The top section pulls free once the joint has been placed correctly in the wet concrete.
Furnished in three depths: 1″, 1.5″ and 2″ (25.4 mm, 38.1 mm and 50.8 mm). Standard length is 10’ (3.05 m).
1100 water-based concrete curing compound is formulated from hydrocarbon resins and may be used on interior, exterior, vertical, and horizontal concrete surfaces. Once applied, 1100 forms a premium-grade membrane that retains an optimum amount of water in freshly placed concrete for complete hydration of the cement. NOTE: After approximately four weeks, the membrane begins to chemically break down when exposed to UV rays. The membrane will eventually dissipate from the surface. This process is sped up by exposure to traffic and UV light, as well as weathering conditions. This product is formerly known as 1100-CLEAR.
1100 has been used on both interior and exterior applications where paint, resilient tile, or resilient flooring may be applied later. Because of the wide variety of coatings, paints, adhesives, and toppings available, contact the manufacturer of the flooring system or subsequent coating or topping for application approval over concrete cured with resin-based curing compounds. A small test application is always recommended.
SURE-STEP slip-resistant additive is a finely ground polymer material for addition to concrete sealers for slip resistance. This additive can be added to most film-forming water- and solvent-based sealers, including the CS-309™, DECRA-SEAL™, VOCOMP®, TIAH®, and SEAL CURE™ products from W. R. MEADOWS. Please consult sealer manufacturer prior to using if using a product not listed above.
SURE-STEP provides improved abrasion resistance and is more comfortable to bare feet on treated surfaces than sand or aggregate additives. The product’s low density and insolubility characteristics will help reduce settling and provide optimum performance in its various applications without changing the viscosity. Due to its low density, SURE-STEP stays suspended in thin materials.
SURE-STEP is perfect for use on areas where a slip-resistant surface is desired. This includes walkways, driveways, garage floors, patios, and other surfaces.
PREMOULDED MEMBRANE VAPOR SEAL WITH PLASMATIC CORE (PMPC) is a patented seven-ply, weather-coated, permanently bonded, semi-flexible vaporproofing / waterproofing membrane. It is composed of an exclusive PLASMATIC CORE suspended mid-point between two layers of a homogeneous, bituminous material, and then sealed under heat and pressure between liners of asphalt-impregnated felt and a glass-mat liner. An asphalt weather coat is applied to the glass-mat liner and covered with a polyethylene anti-stick sheet.
PMPC provides a positive, easy-to-install, economical, true vaporproofing and waterproofing system for horizontal applications. Properly applied, it stops moisture migration in footings, concrete floors, and structural slabs. PREMOULDED MEMBRANE VAPOR SEAL WITH PLASMATIC CORE is both waterproof and vaporproof.
It offers a perm rating of less than 0.002 perms, the lowest in the industry. The product is the ultimate when a true vapor seal is required. Among its unique features is the built-in protection course, which resists jobsite puncturing and the abrasive action of concrete placement. PMPC conforms to ASTM E 1993-98.
The exclusive PLASMATIC CORE adds flexibility, greater tensile strength, and excellent handling characteristics, in addition to providing unequalled vapor barrier properties. PMPC helps meet and maintain the maximum slab moisture transfer rate of 3 lb./1000 sq. ft./24 hours, as allowed by the flooring industry’s specifications.
PMPC, when properly applied, is designed to stop moisture migration (liquid or vapor) in footings, concrete floor slabs, and structural slabs, which greatly reduces fungus, mildew, and mold. It is especially useful under slabs overlaid with wood, tile, epoxy, and urethane coatings, carpeting, and resilient or seamless flooring systems, since it helps prevent warping and buckling caused by moisture migration. PMPC also greatly reduces radon gas from entering the structure.
