Without effective waterproofing, a basement can become the perfect breeding ground for mold and mildew. The constant expansion and contraction of your basement walls can lead to small cracks, and water seepage. Mar-Flex is a proven waterproofing system, designed to give your home reliable and cost-effective protection, year-round. The Mar-Flex system combines a tough, seamless polymer membrane that prevents moisture from seeping in through your basement walls, drainage board and effective footer/foundation drainage. When combined these ingredients actively keep moisture away from your basement walls. For more information on this product visit the Marflex website.
