Basement & Radon Solutions installed a 9-mil white 100% woven reinforced radon ready crawl space system. A radon piping system was installed below the ground liner. The piping system will be used in the future when the home is tested for radon gas and requires a complete radon system. If so then it would only need a radon fan and cost more than half the price if done later. A 9-mil woven ground liner will control moisture vapor and dampness from the ground. Most crawlspace liners are partially reinforced, our woven liner is 100% reinforced and tough unlike competitive brand liners that are only 10% reinforced. This product will not off gas (known on Google as crawlspace cat urine odor”, go ahead and check it out), we guarantee it!! Our woven ground and wall liners are antibacterial, meaning mold and other organic growth will not grow to the liner. It was a pleasure helping Dorothy get both of her town homes happy, safe, and healthy!”
