Crawlspace Sealing 
for Radon Mitigation

Crawlspace sealing is a necessary part of radon mitigation, if you have a crawlspace. Sealing can also help if you have moisture issues in your crawlspace.

Dura-Skrim Heavy Duty Plastic

What I use is 6 mil and 12 mil Dura-Skrim vapor barrier that consists of two sheets of high strength polyethylene film laminated together with a third layer of molten polyethylene with diamond reinforced skrim. Basically this translates into English as a very durable plastic. 

Dura-Skrim 6mil 6x100' Roll .............$97.00
Dura-Skrim 6mil 12x100' Roll .............$179.00
Dura-Skrim 12mil 6x100' Roll .............$179.00
Dura-Skrim 12mil 12x100' Roll ...........$358.00

Don't need a whole roll? We do sell 6mil Dura-Skrim by the foot off of either 6' or 12' rolls.

Example: So if you order 1 foot off a 6 foot roll you would get a 1'x6' piece of plastic. Make sure to order enough for at least 1' for overlaps, seams and to run up walls.

Feel free to contact me if you have any questions or need any help calculating what you need.

Dura-Skrim 6mil 6'per foot .............$1.80
Dura-Skrim 6mil 12'per foot ..........$3.60
