MEL-ROL ICF Waterproofing Membrane (Rolled, Self-Adhering)
MEL-ROL ICF Waterproofing Membrane is designed and engineered for use with Insulated Concrete Forms (ICF) technology. It’s also an excellent choice for use on poured concrete foundation walls, Concrete Masonry Unit (CMU) walls, and related applications where waterproofing is critical or hydrostatic pressure is present. MEL-ROL ICF Waterproofing System is a flexible, versatile, dependable, bituminous, roll-type waterproofing membrane. It’s 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. Unique 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 ICF Waterproofing System work together to provide a cost-effective, positive waterproofing system that’s quick and easy to apply.
W. R. MEADOWS accessory products included in the MEL-ROL ICF Waterproofing System are: BEM, MEL-ROL LIQUID MEMBRANE, MEL-PRIME™ adhesive (solvent-based and water-based), POINTING MASTIC, DETAIL STRIP, CATALYTIC BONDING ASPHALT, TERMINATION BAR, PROTECTION COURSE and MEL-DRAIN™ drainage board.
USES
MEL-ROL ICF Waterproofing System provides a cost-effective answer to properly waterproof foundations, vertical walls, and below-grade floors in residential and commercial construction.
MEL-ROL LM – Liquid ICF Waterproofing Membrane
MEL-ROL LM is also available for those that prefer a fluid-applied solution.
The following products will be used in waterproofing ICFs:
MEL-PRIME™ W/B
BEM
MEL-ROL LIQUID MEMBRANE
MEL-ROL
MEL-ROL LM
TERMINATION BAR
RECOMMENDED TOOLS
Broom
Caulking Gun
Chalk Line
Impact Hammer
Paint Brushes and Roller
Surface Preparation … Remove any oxidized foam (rasp) from the surface.
Joint Treatment … All joints in the ICF need to be addressed. For applications of MEL-ROL, if joints in the ICF are wider than ¼” (6.35 mm), they should be filled with either MEL-ROL LIQUID MEMBRANE or BEM prior to priming and installation of the waterproofing membrane. Also, pay close attention to where the wall meets the footing. This area should be treated with BEM or MEL-ROL LIQUID MEMBRANE. This treatment creates a cant where the wall meets the footing. In applications of MEL-ROL LM, all joints need to be filled with BEM.
Application Method …. Follow the same application procedure as indicated on MEL-ROL and MEL-ROL LM technical data sheet. For more detailed application information, see MEL-ROL INSTALLATION GUIDELINES and MEL-ROL LM INSTALLATION GUIDELINES documents.
Priming … When using MEL-ROL to waterproof the ICF, priming must be done. MEL-PRIME W/B should be used as the primer. The prime-coat should be in the range of 5-10 mils. After proper priming (not required for MEL-ROL LM) and joint detail, the ICF surface is ready for the application of MEL-ROL or MEL-ROL LM. Apply the product as outlined in the applications directions listed previously. When using MEL-ROL, TERMINATION BAR is required to seal the top edge.
