Artificial Grass AirDrain Roof Top Drainage at Ft. Worth Hospital 

 

Over the years, many architects and engineers have asked us just how fast will the AirDrain grid drain.  Our reply has always been that the AirDrain is only limited by what is above it and the exit drains.  Due to the fact that the area of an AirDrain part is 1” inch high and has a 92% air void.

Recently, our AirDrain grid was tested using the ASTM D 4716 Hydraulic Transmissivity Standard Test Method. The testing was done using plates on top and bottom of the AirDrain part, setting them to the required slope and adding water from the high side of one end down the slope. AirDrain was draining so fast they had to modify their testing equipment to accommodate the volume of water AirDrain could move!

As it turns out there is practically no resistance to drainage using the AirDrain grid?  The most important factor to consider is the percentage of slope that the AirDrain is sitting on.

To put this in perspective of rainfall, AirDrain can handle anything that Mother Nature throws at it.  On a nearly completely flat surface (1/2% slope) AirDrain will drain 2.85 inches of rainfall in one minute.

For example, it could rain over 171 inches in an hour and AirDrain could drain it on a 1/2% slope. AirDrain can also hold .578 gallons of water per sqft. if needed until it can evacuate to the perimeter exit drains.

No other product on the market comes close to AirDrain’s ability to drain a project, it’s not even close.

So when you see the claims of manufacturers rainfall per hour drainage, ask them if they have the test that really shows a products real world drainage capability.
