Stuff worked awesome! Had a bit of rocks and concrete under vapor barrier and it actually stretched around it when I crawled over it.

Took on a 2400 Square foot encapsulation of my homes crawlspace. Was overwhelming at first but the material quote and outstanding assistance from Larry took majority of the guess work out. Went with 12 mil silverback reinforced poly for the walls and pillars and 20 mil silverback reinforced poly for the floors. 90 pint dehumidifier and pump. Material quote was spot on with just enough material for the job. Entire job took 2 months working at my leisure with the help of my father. Wood moisture readings previous to encapsulation were 18-25% with humidity readings of 80-85% . Wood readings post encapsulation are now as low as 6% some places and cant find a reading over 15% anywhere. Humidity is now steady at 53% with the dehumidifier cycling on and off. Highly recommend fan kit to improve dehumidifier efficiency. This job is not for a first time DIY person but someone with average skills can be successful. I saved about $15,000 by doing this job myself.

Not a professional and I was able install the Diamond Back barrier in my 1600 foot crawl space, mostly by myself, after watching a few videos provided by Crawl Space Repair. I'm not saying it was easy, it took me about 2 weeks and it's not as pretty or perfect as I'd like, but being a 59 year old woman with a few physical limitations I'd say that is a testament to ease of installment. The quality seems very good, but the judge of that will come after a few years. So far I'm happy with the result and I can now store a bunch of stuff under the house.

Great product for encapsulating crawlspaces and very efficient in shipping the items the next day.

Works great very strong just make sure your blade or scissors is sharp to cut through this durable vapor barrier
