No other system comes close in ease of install, price value player safety and performance!
Here is the ASTM D4716 Flow Rate per Unit Width and Hydraulic Transmissivity Testing for actual drainage capacity, at an 1/2% slope. The AirDrain will actually drain 2 inches per minute per sqft. No other product comes close! http://bit.ly/2cQUREL
The ASTM D4716 was done with 2 metal plates top and bottom and the grid tilted at a 1/2% slope. This is the only way to be able to claim drainage per hour. Don’t letem kid ya ! If they don’t have this test ask them why?
