PERMINATOR provides the vapour barrier industry with a highly effective, economical choice for helping to reduce the penetration of moisture and water vapour through the slab into the structure, thereby helping to reduce fungus, mildew, and mould growth.\u00a0 PERMINATOR also helps reduce radon gas from entering the structure.<\/p>\n<p><strong>New resin technology allows dramatically greater puncture resistance while maintaining one of the lowest perm ratings in the market.<\/strong><\/p>\n<p>PERMINATOR is tough enough to withstand normal construction jobsite conditions and traffic.\u00a0 It will not crack, puncture, snag, split, or tear easily.<\/p>\n<p>PERMINATOR prevents uncontrolled moisture from entering the slab allowing the slab to maintain the maximum slab moisture emission rate and relative humidity level as allowed by flooring manufacturer\u2019s specifications.<\/p>\n<p>PERMINATOR is available in 10 mil and 15 mil thicknesses.<\/p>\n<p>Installation is quick and easy. All joints\/seams, both side and end, should be overlapped 152.4 mm (6\u201d) and taped using 101.6 mm (4\u201d) wide <a href=\"https:\/\/can.wrmeadows.com\/en-ca\/perminator-tape-canada\/\">PERMINATOR TAPE<\/a> from W. R. MEADOWS.\u00a0 PERMINATOR rolls fast and smoothly over level tamped soil or compacted fill.<\/p>\n<p><strong>USES<\/strong><\/p>\n<p>PERMINATOR underslab vapour barrier is primarily designed for underslab construction, where the soil has been tamped and levelled or compacted fill has been applied.\u00a0\u00a0 Sheets are unrolled as is or cut to size and installed using the overlapping method.\u00a0 Overlaps are 152.4 mm (6\u201d) wide and these seams are sealed using 101.6 mm (4\u201d) wide PERMINATOR TAPE.<\/p>\n<p>PERMINATOR can also be used as a protection course for waterproofing membranes.\u00a0 The desired sheet lengths are cut to size and retained at the top of the waterproofing membranes by PERMINATOR TAPE or TERMINATION BAR from W. R. MEADOWS.<\/p>\n<p>PERMINATOR is suitable for use under radiant heating concrete slabs systems.\u00a0 The product can also be used in crawlspace applications.<\/p>\n<p><strong>FEATURES\/BENEFITS<\/strong><\/p>\n<ul>\n<li>Available in 10 mil and 15 mil thicknesses<\/li>\n<li>Helps reduce the penetration of moisture and water vapour through the slab into the structure.<\/li>\n<li>Helps reduce fungus, mildew, and mould.<\/li>\n<li>Helps reduce radon gas from entering a structure.<\/li>\n<li>Resistant to methane gas.<\/li>\n<li>Tough enough to withstand normal construction jobsite conditions and traffic \u2026 will not crack, puncture, snag, split, or tear easily.<\/li>\n<li>Installs quickly and easily over tamped grade \u2026 no gravel, fill, or sand needed.<\/li>\n<li>PERMINATOR prevents uncontrolled moisture from entering the slab allowing the slab to maintain the maximum slab moisture emission rate and relative humidity level as allowed by flooring manufacturer&#8217;s specifications.<\/li>\n<li>10 or 15 mil thickness clearly marked on membrane for easy visual identification on jobsite<\/li>\n<li>VOC content is 0 g\/L.<\/li>\n<\/ul>\n<p><strong>PACKAGING<\/strong><\/p>\n<p>10 mil: \u00a0\u00a0\u00a0 4.3 m (14\u2019), 64 m (210\u2019) long<br \/>\n15 mil:\u00a0\u00a0\u00a0\u00a0 4.3 m (14\u2019), 42.7 m (140\u2019) long<br \/>\n*Factory welds are available by special order if larger width rolls are required.<\/p>\n<p><strong>SPECIFICATIONS\/STANDARDS<\/strong><\/p>\n<ul>\n<li>Meets or exceeds all requirements of ASTM E1745 Class A, B &amp; C.<\/li>\n<li>American Concrete Institute (ACI) 302.2R: Guide for Concrete Slabs that Receive Moisture Sensitive Flooring Materials makes a suggestion to use materials having 0.01 perms when flooring materials require protection lower than that determined by ASTM E1745.

This will sandwich PERMINATOR between the footing, vertical wall, and poured concrete floor.\u00a0 (See illustration.)\u00a0 This will help protect the concrete slab from external moisture sources once the slab has been placed.<\/p>\n<p>Before placing concrete slab, make sure all penetrations, block outs, and damaged areas are repaired\/addressed.<\/p>\n<p>Numerous municipal building codes do not allow the placement of vapour barriers over the footing, due to breaking of the bond between the wall and footing.\u00a0 Although this is not an optimal application method, W.
