Oklahoma City has been receiving a facelift lately with the MAPS Program. With all of the improvements along the Oklahoma City River and a booming entertainment district in Bricktown, Downtown OKC has many projects that will make traffic and pedestrian travel easier. One of the projects in Downtown OKC is the Pedestrian Parkway 180 near the Devon Tower. This will allow pedestrians to have access to multiple buildings from the parking garages and a shorter route from building to building while adding beauty to the downtown area.
Drainage in an area that is mostly hardscaped is typically a HUGE issue, but with AirDrain providing a 1” void beneath the whole parkway any drainage needs are met and exceeded! When the AirDrain is installed below paver stones it not only allows water to flow to the exit drains, it also provides a strong platform for the pavers to lay evenly on. With no large unsightly drainage grates in the foot path for people to trip over or fall in.
Approximately 17,000 sqft. of pavers installed by Elevated Paver Systems completely covers the AirDrain beneath all of the landscape and hardscape features. This means the 1” of air hidden below can drain over 171 inches of rain an hour!
AirDrain grid also provides stabilization, allows for water lines, electrical lines and even radiant heat tubing can be installed below the surface.
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 horizontally drain 171 inches per hour.
