Crawl Space Wall Liners
Block and concrete walls wick moisture from the soil outside. A wall liner, fastened with a termination bar and sealed to the floor liner, stops that moisture from reaching the air. Together with the floor barrier, it closes the space on every side so humidity can be controlled.

Common questions
Does the liner hide wall problems?
We inspect the walls first. Cracks and leaks are fixed or drained so they are not hidden.
How high does it go?
Usually to near the top of the wall, depending on the design.
Is it flame-rated?
Products vary, and we choose and explain the right one.
