| What is Viper® VaporCheck? |
|
|
| Viper is a triple ply, extrusion coated, virgin polyethylene membrane designed to act as a vapor/moisture barrier underneath concrete slabs. It offers premium protection against soil gas and moisture diffusion through the slab. |
| |
| Why is a Vapor Barrier Neccessary Under Concrete? |
| Concrete is a naturally porous material. Without a vapor barrier, air pressure can cause soil gasses and water vapor to migrate through the slab into a home or building. In some instances, methane and radon levels in basements have risen high enough to be fatal. Moisture has been known to cause mold, mildew, fungus, rust stains, odors, floor failure and more. |
| |
| What Sets Viper® VaporCheck® Apart? |
During construction, heavy foot traffic often compromises the integrity of the vapor barrier. Punctures and tears due to construction provide openings for vapor migration. Viper VaporCheck is specifically designed to resist tears and punctures during construction. Testing shows that Viper VaporCheck is the strongest vapor barrier on the market. |
