AirDrain Synthetic Grass Roof Top Installation

AirDrain is capable of holding .576 gallons of water per sqft. if needed until it can evacuate from the green roof to the perimeter exit drains, which is a holding capacity equal to approximately 6 inches of compacted gravel. 


Build a better green roof with AirDrain. What drains better than air !

Unlike traditional shock pads or e-layers the AirDrain grid is 1″ high, extremely light weight at 3.1 lbs per 7 sqft., 233 psi (unfilled) and has a 92% air void.

Installing the AirField System in green roof applications results in a more stable surface area and a more consistent GMAX across the project. AirDrain’s delivers a 14.7% reduction on cement and a 19% reduction on an aggregate base in GMAX. And that reduction and consistency will stay for the life of the field with AirDrain .

Here is the ASTM D4716 Flow Rate per Unit Width and Hydraulic Transmissivity Testing for actual drainage capacity, at a 1/2% slope. The AirDrain will actually drain 171 inches per hour.

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 let’em kid ya! If they don’t have this test, ask them why.

There is a big difference between real world drainage on an installed Green roof project and some manufacturers claims of drainage per hour, where they run water through their product being held vertically in the air and claim drainage per hour. You have to vertically drain it into the sub drainage. And then move it horizontally to the perimeter drains that’s draining a project.

It’s vertical and lateral drainage unmatched in the industry, all but eliminates standing water and moisture trapped on the rooftop. Making infill migration a thing of the past.

No other product stacks and ships more compactly, reducing the number of trucks and the amount of fuel required to transport AirDrain to 1 truck on a 83,7980k sqft. project. That goes straight to the bottom line!  

AirDrain drainage can’t be beat by anyone’s product period.

AirDrain’s strength and durability allow it to be used under multiple multiple turf replacements on a green roof project.

In a cost value and performance comparison there is only one choice, AirDrain!
