How to Keep Basements Dry: Use Membrane Capillary Breaks Above Footings

It’s important to separate a foundation wall from damp soil so that migrating moisture does not reach the structure’s framing and/or interior. To preempt the costly problems from ground moisture reaching foundations, contractors routinely employ these solutions: Asphalt dampproofing on the exterior surface of foundation walls A layer of polyethylene and crushed stone under the basement […]
