ShockWave™ Drainage Board doesn't just drain groundwater, it gulps it !

The best way to assure a dry foundation is to take water pressure and backfill pressure off the waterproofing membrane.

ShockWave drainage board gulps up to 101.11 gallons per hour per linear foot of groundwater to eliminate any possibility of hydrostatic pressure.

It stands up to backfill and bulldozers, too, with 283.72 psi of compressive strength. So it can "bounce back" to its original configuration, if compressed.

And because Shockwave is made from 100% post-consumer recycled materials that would otherwise be deposited in landfills, it's green and LEED® friendly.

Contractors love ShockWave, too, because it's light and easy to install, from the top of the footing to the grade line, shortly after membrane application.

You'll find 1" and 2" ShockWave installations on custom-built residential, multi-family and commercial buildings across the U.S.

For heavy-clay soil, or clay & rock soil where drainage conditions are extreme, nothing compares to the performance delivered by ShockWave.

• Crush-Resistant Memory (CRM) acts as a shock absorber so backfill doesn't allow debris to harm waterproofing membrane
• Closed cell, cross-linked foam resists water absorption to prevent thermal transfer of below-grade ground temperature
• Made from inert, environmentally-friendly "Green" recycled foam products
• ShockWave won "Expert's Choice" for Most Innovative Product at World of Concrete 2007

Here's why ShockWave is GREEN: ShockWave is made of 100% post-consumer recycled polyethylene-polyolefin foam products that would otherwise be deposited in landfills.
