## Description

Whitecap Vapor Barrier 12 Mil – 4’ x 200’ Heavy Duty White Woven Polyethylene Moisture Barrier Plastic Sheeting for Crawl Space Encapsulation, Ground Cover & Drop Cloth - desertcart.com

Review: I would buy this again - The materials from whitecap are exceptional quality and very puncture resistant. They were packaged and delivered well from desertcart. The product weighed over two hundred pounds and there was no damage to the cardboard packaging. It arrived on time.
Review: High quality crawl space encapsulation vapor barrier. - Received the vapor barrier on time and in good condition. Using this for encapsulation of an old crawl space in a 100+ year old 2 story home which was moved to the present site about 1959. Lots of old foundation concrete fragments to deal with and the white woven sheeting is expected to provide ample protection from the fragments as well as sealing off ground moisture. Previously purchased some non-reinforced sheeting from a different supplier, which has had some small punctures and isn't working as good as the woven sheeting.

### ⭐⭐⭐⭐⭐ Heavy grade and easy installation.
*by P***E on June 28, 2025*

Repaired a concrete crack and replaced the old barrier. This product was easily installed and seems to be of high quality. As a former disaster restoration specialist I’ve seen many barrier encapsulation projects, I believe this is one of the best for the situation that we have to correct.
