Foundation Protection Board

Help protect your foundations and other below-grade walls from moisture intrusion by protecting the exterior waterproofing from damage due to backfilling. Durable, impact-resistant XPS fanfold boards are easy to cut, carry and install.

The dense, closed-cell construction and tough plastic facers helps it to resist moisture absorption and decomposition from long-term exposure to water and chemicals in the soil.
