For many years PERMINATOR has been used in applications from schools and hospitals, to universities and sports stadiums and has been continually revered for its outstanding jobsite performance and exceptionally low perm rating.
PERMINATOR underslab vapor barrier is primarily designed for underslab construction, where the soil has been tamped and leveled or compacted fill has been applied. PERMINATOR can also be used as a protection course for waterproofing membranes. 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.
When it comes to jobsite performance and strength, PERMINATOR 10 and 15 mil vapor barrier and its proprietary technology significantly exceeds the requirements of ASTM E 1745 (0.1 perms), as well as the recommendation of ACI 302.2R. ACI 302.2R states that a vapor barrier is to be installed with a perm of less than 0.01 in areas where the requirements of ASTM E1745 are not sufficient to protect the floor.
PERMINATOR exceeds this ACI requirement by 37%, while at the same time providing the peace of mind that its superior puncture resistance will protect this low perm rating by resisting punctures on the jobsite. Thus providing the entire building team with the lowest vapor permeance with puncture resistance that is over 45% better than required by the ASTM E1745 standard.
