Mar-flex Waterproofing and Building Products retains its commitment to quality affordable products that are effective years after installation and backed by an industry-leading warranty. Mar-flex presents DampFUSION, which is a water-based acrylic dampproofing membrane approved for masonry, block, pre-cast and poured concrete wall foundations. This membrane stops water vapor and protects the foundation against leaks, which can damage the structure. DampFUSION sprays-on easily and dries as a seamless, monolithic coating. It can be applied to pre-existing damp walls and the tops of foundation walls. Like any effective membrane, it has no odor and dries to a gray color to seamlessly match concrete for added versatility. Choose Mar-flex products when you need easy installation, twenty four hours a day and seven days a week support, and products that are guaranteed to be effective, durable, affordable, and made of the finest quality materials available.
