Waterproofing Solutions: Waterproofing Membranes

At Keystone Foundation Repair we use Mar-flex’s proven waterproofing membranes, Mar-flex 5000 and Quick Seal, along with Mar-flex Shockwave board to provide unequal waterproofing capabilities. Mar-flex developed its multi-step system of products to protect poured foundation walls. We only use the most trusted membranes for our waterproofing solutions.

  1. A highly-impermeable membrane (Mar-Flex 5000 or Quick Seal) is applied to the exterior concrete walls. This specially formulated spray coating seals the concrete from water being able to penetrate to the interior.
  2. After the membrane is applied, a high-quality drainage board (Mar-Flex Drain & Dry) is installed to protect the membrane, adds additional insulation R-value and helps channel water away from the wall and the foundation.
  3. We recommend you install the proper drain tiles and pipe to properly transport water from the foundation away from your home or building.
