Playground drainage with ASTM Testing for 6 ft. and 9 ft. fall heights 

( Tested numbers are on concrete with NO INFILL, infill numbers should be even better )

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.

32”x32”x1”= 1024” AirDrain has 92% air void 1024”x .92 = 942.08” 7 sqft Grid can hold 4.078 gallons of water or .5826 gallons per sq ft AirDrain has the ability to pull the water through the pad, with gravity. Anything an inch off the earth brings gravity into play. It will help pull the water through the pad, allowing it to drain much faster than without it. And of course with the 92% air, move it straight to the exit drain.

No other product comes close!

AirDrain Playground Drainage with its 100% vertical drainage and 92% air void is unmatched by any other drainage product on the market. By raising the entire profile off the subbase, creating a 1” air void, and bringing gravity into play, this allows the area to dry quickly and efficiently.

The result is a more stable surface area and consistent HIC across the project, all but eliminating infill migration, a huge maintenance cost and an inconsistent HIC across the playground (which can drastically affect the safety of the project, putting owners in an extreme liability risk scenario).

AirDrain’s strength and durability allow it to be used under multiple turf replacements on the project. In a cost value and performance proposition there is only one choice, AirDrain!

No other product stacks and ships more compactly, reducing the number of trucks and the amount of fuel required to transport to the job site typically to 1 truck at 85,500 sqft. per project. Don’t forget shipping costs go to the bottom line AirDrain can't be beat !

Installing the AirField System results in a more stable surface area and a more consistent GMAX across the project. AirDrain 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 project with AirDrain.

AirDrain drainage all but eliminates infill migration and a floating field, and helps brings a consistent GMAX across the entire field. (which can drastically affect the safety of the project, putting owners in an extreme liability risk scenario)

For playground drainage the AirDrain System can be placed on the prepared subbase. Whether using loose fill products, such as engineered wood fiber or rubber chips, or using unitary surfaces, such as rubber tiles or poured in place rubber, the playground area needs proper water drainage.

Wood chips can be placed directly on top of the geotextile. The filter fabric retains the wood chip particles while allowing water to freely enter the drainage core.
