The Delta MS membrane provides reliable protection to keep basements perfectly dry by directing moisture away from the foundation walls. One of its unique advantages is that, even if the concrete behind it cracks, the Delta MS membrane continues to block water and prevent infiltration. Not only does this membrane provide long-lasting waterproofing on its own, but it is also designed to protect other waterproofing products applied underneath, such as Aquabloc. Thanks to its effectiveness and the high level of protection it provides to foundations, the Delta MS membrane is a staple that we install in almost all of our French drain projects.
