Mar-flex Waterproofing and Building Products presents the Moisture Block 361 Water Based multi-functional dampproofing membrane. Moisture Block 361 is a patented, asphalt emulsion coating that is designed to dampproof and protect concrete and most concrete masonry surfaces. The single component liquid applied coating offers good resistance to temperature changes, as well as excellent weatherability, and the ability to effectively protect against water penetration. The durable film bonds to most surfaces, but is recommended for below grade dampproofing of precast concrete, poured concrete, and concrete masonry. This membrane also functions as a vapor barrier on exterior faces of the interior walls of above-grade exterior cavity walls, and excels as a utility coating on wooden posts, pilings, and other metal surfaces set into the ground. When you need a versatile and reliable dampproofing solution that is made from quality materials choose none other than Moisture Block 361.
