Playground drainage with ASTM Testing for 6 ft. and 9 ft. fall heights
( Tested numbers are with NO INFILL, infill numbers will 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.
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 1 truck on a 93k sqft. project. Don’t forget shipping costs
AirDrain can’t be beat !
Installing AirDrain 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)
