Plastic Membrane for Waterproofing

The plastic membrane for waterproofing is made in the USA from 100% High-density polyethylene (HDPE). It is available in various sizes and thicknesses. The thicknesses range from 30 mil to 100 mil ( a mil is a 1,000th of an inch). Roll heights range from 18” to 60” with the lengths mainly being 100’ with a few rolls being 80’ in length. They are waterproof, UV resistant, and non-biodegradable. The plastic is also resistant to insect and rodent damage, will not rot/mildew. Multiple rolls of HDPE can be connected using the double sided HDPE seam tape.

We have this stocked in Kansas City, MO and typically ships within one business day.

Material Thickness:
30 mil = 1/32”
40 mil = 3/64”
60 mil = 1/16”
80 mil = 5/64”
100 mil = 3/32”
