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. The two components are laminated together under strict quality-controlled production procedures.
A handy overlap guideline is printed 2 in(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 is quick and easy to apply.
mel-rol-waterproofing-membrane (1)W. R. MEADOWS accessory products included in the MEL-ROL waterproofing system are: BEM, MEL-ROL LIQUID MEMBRANE, MEL-PRIMEu0099 adhesive (solvent-based and water-based), POINTING MASTIC, DETAIL STRIP, CATALYTIC BONDING ASPHALT, TERMINATION BAR, PROTECTION COURSE and MEL-DRAIN drainage board.


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.

Offers a quick and easy-to-apply system for maximum productivity.
Special membrane-to-membrane adhesion provides additional overlap security.
Meets or exceeds the test requirements of all currently applicable specifications.
Components work together for positive waterproofing protection.
Handles with ease on the jobsite.
Available in a low temperature version for use when air and surface temperatures are between 20 degrees F and 60 degrees F. An extra-low temp version is also available, ideal for application in extra-low temperatures down to 0 degrees F.

38.5? (977.9 mm) wide x 62.5? (19.1 m) long, one roll per carton.

Provides 200 ft.2 (18.6 m2) per roll. Gross coverage is 200 ft.2 (18.6 m2). [Net coverage is 187.5 ft.2 (17.4 m2) with overlap of 2 u00bdu0094 (63.5 mm).]

Store membrane cartons on pallets and cover if left outside. Keep materials away from sparks and flames. Store where temperature will not exceed 90 degrees F for extended periods of time.

ASTM D 570

Surface Preparation Concrete should be cured at least 72 hours, be clean, dry, smooth, and free of voids. Repair spalled areas; fill all voids and remove all sharp protrusions.

A handy overlap guideline is printed 2in (63.5 mm) in from the material edge on each side, assuring proper overlap coverage and assisting in maintaining a straight application. The polymeric waterproofing membrane is protected by a special, easy-to-remove release paper. The exposed membrane strips on the material edges are protected by a pull-off release strip. Exposed polymeric membrane strips are provided on both sides of MEL-ROL for positive membrane-to-membrane adhesion in the overlap area u0085 note the detail, as shown in inset photo.


Temperature  Apply in dry, fair weather when the air and surface temperatures are above 40 degrees F. Do not apply to frozen concrete.
MEL-ROL LOW TEMP can be used when air and surface temperatures are between 20 degrees F and 60 degrees F.

Surface Conditioning Apply MEL-PRIME adhesive to surfaces that will be covered within one working day. If left exposed overnight, additional adhesive must be applied. Follow all instructions and precautions on containers.

REMOVE release paper from MEL-ROL from the top edge of the roll and firmly press exposed area to the wall. Remove the release paper from the rolls in a downward direction, pressing MEL-ROL into place on the wall.
