Ever wonder what the black coating on a foundation wall is for? 👀
That’s damp proofing.
On this foundation, we applied Mar-Flex to the exterior of the poured walls before the area is backfilled.
The coating helps protect the below-grade concrete from moisture and water pe*******on once the foundation is surrounded by soil. It’s one of those parts of a project that eventually gets completely covered up, but it plays an important role long after construction is finished.
A lot goes into a foundation before the house ever starts going up above it.
