A good drainage board is the backbone of a waterproofing system. They prevent the buildup of hydrostatic pressure, transport water to drainage systems and protect crucial dampproofing and waterproofing membranes. Mar-flex believes that drainage boards can do even more, however. Our Drain & Dry Drainage Board, made with Ecose Technology, brings the 21st Century revolution in green building materials to the drainage board industry.

• Meets the needs of builders, energy conscious home-buyers and/or local building codes
• Combines high R-value, drainage and protection into one product
• Good drainage and thermal insulation properties
• Easy to handle
• Can be used in any geographical area
• Compatible with any of the Mar-flex waterproofing or dampproofing membranes

Drain & Dry Drainage boards are produced using an innovative process which converts bio-based materials into an inert polymer that bonds mineral wool strands together. This process eliminates the formaldehyde and phenols found in traditional binders and insulation. Like traditional polymer-based drainage boards, Drain & Dry boards offer ample protection for waterproofing and dampproofing membranes during backfilling operations as well as excellent drainage properties. Drain & Dry is also effective as thermal insulation, further bolstering its credentials as a green building material.

Drain & Dry is easy to handle and install, making it an ideal product for commercial and residential drainage board needs. Drain & Dry boards should be installed from the top of the footing to the grade line and are applied shortly after membrane application and before backfilling operations start.

Drain & Dry is another addition to Mar-flex’s selection of green building materials, and can be used towards LEED building credits.
