Many contractors who don’t specialize in repairing crawl spaces will often try to remedy the dampness problem by installing regular 6 mil poly plastic. This was the case with this home in Malvern, PA. But the black plastic was not doing the job because there were gaps and holes everywhere. The result was more moisture.
The customer hired us to install the CleanSpace Vapor Barrier in their crawlspace. CleanSpace is 20 mil thick and fiber enforced. This means it will not get punctured on the rough dirt terrain if you crawl across it. It also means that we can anchor it to the wall so that it won’t move around and get separated. A special high strength white tape is used to seal the seams to prevent any air bypass. CleanSpace is made with an antimicrobial coating so that it won’t grow mold on it and it comes with a 25 year guarantee against puncture holes.
