<p>Our exterior foundation waterproofing membrane is UV resistant, waterproof, and non-biodegradable. It is also resistant to insect and rodent damage, and it will not rot/mildew. It is proudly made in the USA from 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 10” to 60” with the lengths mainly being 100’ with a few rolls being 80’ in length.<br><br>Multiple rolls of HDPE can be connected using the double sided HDPE seam tape.<br><br><strong>Above in picture 2:</strong> The barrier was installed a few inches away from the concrete wall to allow for a occasional visual inspection to ensure that water was not flowing around the barrier and pooling against the wall.<br><br></p> <p>This material is stocked in Kansas City and typically ships within one business day.</p> <p> </p> <p><strong>Material Thickness:</strong><br>30 mil = 1/32”<br>40 mil = 3/64”<br>60 mil = 1/16”<br>80 mil = 5/64”<br>100 mil = 3/32”</p> <p><iframe src="https://www.youtube.com/embed/SP-dw9mCTVQ" title="High Density Polyethylene Compared" width="745" height="419" allow="accelerometer; autoplay; clipboard-write; encrypted-media; gyroscope; picture-in-picture" allowfullscreen="" frameborder="0"></iframe></p>
