Mar-flex Waterproofing and Building Products presents the ShockWave™ drainage board. ShockWave™ is the winner of the Expert’s Choice Award for Most Innovative Product at the World of Concrete convention, and is one of Mar-flex’s flagship products. ShockWave™ is built incredibly durable, able to withstand 283.72 PSI of compressive strength with a Crush-Resistant Memory system that acts as a shock absorber so backfill doesn’t allow debris to harm the waterproofing membrane. Its closed cell cross-linked foam resists water absorption to prevent thermal transfer of ground temperature and is designed for heavy-clay soil or clay and rock soil where drainage conditions are extreme. ShockWave™ is able to absorb up to an incredible 101.11 gallons of water per hour per lineal foot, eliminating any possibility of hydrostatic pressure. ShockWave™ is manufactured from 100% post-consumer recycled materials that would otherwise end up in landfills, making it a green product and LEED® friendly. This popular drainage board solution can be found on many custom-built residential, multi-family, and commercial buildings nationwide. When you need the most effective drainage board solution the industry has to offer, choose the name you can trust, ShockWave™.
