If you’ve installed a lot of basins, you will know two things A) you have to dig deep (36” minimum) and B) If the basin floats, you have to start over. This basin has slits all over it, guaranteed not to float and your digging depth is 24”.

I'm a first time home owner. My Wife complained about a musty, moldy smell in our family room located above the crawl space. I ordered this product along with the "T" pins, seam tape, and caulk. After removing the old insulation on the floor joists, I cleaned all the rocks and debris out. Then I started installing the liner right over the dirt floor in the crawl space. At first I was only going to run it up about a foot on the walls, but my crawl space was 28'x16'. That gave me plenty on material to run all the way up the walls. I couldn't be happier with all the products I purchased and most importantly, no more smell. I even ran a heating/ac duct into the middle of the crawl space and even pumping air into the space, there is no smell. Well worth the money I spent and saved. I took me four evenings after work to complete the job.

This stuff is sticky! Take your time when installing.

I bought this to seal below grade EPS insulation and the vapor barrier on top, all to be covered with a slab of concrete. It was expensive and the shipping added another $15 dollars to the total ... but it was absolutely necessary, worked really well, and was the proper product for the job. Good professional-grade quality.

This worked well for the 20mil SB.
