First a fact about Plastic liners verses Concrete, Don’t be fooled
Over the past few years I have been in thousands of crawlspaces and had a first hand look at expensive plastic liners installed in peoples crawlspaces. What I have found is Most Companies who sell this service recommend or pitch there customers a dehumidifier. Reason is because that system does not eliminate moisture in a crawlspace it simply covers up the problem like a band aid, If you notice in the picture, all the seams are coming unglued do to the moisture and allowing water to seep through and on top of the liner. Plastic liners can easily be removed with in a matter of minutes. Concrete with a properly installed drainage system like are sure flow system and vapor barrier eliminates moisture and lowers high levels of Radon up to 80% for a healthier home. It is a permanent solution and becomes a mini basement. In most cases Concreting a crawlspace with proper drainage can be completed in one day and cost about the same or less than a plastic liner, and creates a dry usable space.
