Order only took 1 week to arrive. 12 mil for bottom, and piers. 6 mil for walls. I have a micrometer tester and the thickness is right on. The length, however, is about 2-3 inches short of the listed length of 13'4". I'd give higher rating after it's actually installed.



I have plenty of interesting decisions to make. This is my approach:

1. Using the longest sheets as I can and cutting minimally to a get around the piers. I'm using 2 pieces to wrap the piers: one around the pier walls and one around the bottom that I'll tape together. I modeled how the pieces would wrap around circular and square piers to get it right.

2. Took 2-3 days to clear out the debris from new construction and leveling out the crawlspace. I pushed the clods up against the wall edges.

3. Plannng to keep drain pipes on top of barrier to the extent practical.

4. There are some wood supports that are up against the foundation walls that I plan to go around so they will be inside-above the encapsulated area rather than underneath.

5. I'll cut the long pieces before taking them down into the crawlspace of course. But I'm not cutting across where the piers are until I have it in the crawlspace. We'll see how that works out.

6. Tyvek suits, good dust mask, gloves, and goggles are a must. I had a lot of dirt mounds from the recent remodel that needed leveling with a small pick and small army style shovel. Too many clods to break up so I pushed them to the edges.

7. The foundation wall heights are not consistent so I'm just picking a line height and going straight across.

I have been very pleased at the quality of the 12 Mil SilverBack™ vapor barrier and with the Waterproof Seam Tape. The 13'4" width has worked very well for sizing sheets to lay down between the concrete pillars, and even the manufactured seam at half this width has been a convenient guide for cutting smaller sizes to go up the end walls or on the pillars. I've never undertaken such a big task in such a big, dark, damp space. But I found that proper lighting and steady work in one area at a time led to success that grew until the whole project was done. I ended up with a dry, clean, all-white encapsulation and look forward to using my crawl space for storage now that a dehumidifier has been hooked up.

After receiving an expensive estimate for encapsulating my crawlspace, I decided to do it myself. This Silverback material was easy to work with in my opinion. I did most of the installation myself. I used a sharp pair of scissors to cut it. I used a drywall T and a sharpie to mark a straight line right on the back of the material.

I purchased the 12 Mil SilverBack™ to encapsulate the crawl space under our cabin. The products were all as described and of excellent quality. The space after installation looks great and there was immediate improvement by eliminating orders and moisture problems contributing to a musty smell. I highly recommend the products and give excellent marks to CrawlSpace Repair for the service they provide.

Exceeded expectations! Very good quality and shipping was fast easy to unroll , cut and install. Replace old 6 mil plastic that had been down for years. The 12 mil is far better quality and durable.
