AirPave Grass Paver System

Previously, drainage cells were difficult to assemble, costly to ship, and extremely expensive. Now, with AirPave’s patented quick connectors, assembly is a snap. What’s more, the AirPave geocell stacks for efficient shipping and storage. All of this at an incredible price makes AirPave the superior geocell for any porous paving project.

From fire lanes, overflow, and event parking, to temporary and stadium parking, the AirPave grass pave system delivers. The incredibly strong AirPave geocell prevents rutting from traffic and protects turf roots from damage.

AirPave also enhances the environment by naturally filtering auto and air pollutants while reducing hot surface temperatures. By routing rainwater directly into the earth as nature intended, the need for costly storm water structures can be drastically reduced or completely eliminated.
Create beauty and comfort with the unbeatable price and performance of an AirPave grass pave system.

AirDrain Drainage System

AirField Systems AirDrain grid creates a GMAX/HIC that is consistent across the entire synthetic playing surface. Unlike traditional shock pads or e-layers the AirField Systems AirDrain grid is 1″ high, extremely light weight at 3.1 lbs per 7 sqft., 233 psi (unfilled) and has a 92% air void, giving it unmatched vertical and lateral drainage. AirDrain also creates it’s own perched water table on the bottom of the 11″ sand profile to promote healthy root growth for natural turf surfaces. The five year research project was jointly funded by the United States Golf Association and AirField Systems and was a collaborative effort between Texas A&M

Benefits of an AirField System Design include:

1 to 3 more days of plant available water stored in the root zone (depending on climate)
Significantly reduces daily irrigation needs (as told to us by our customers)
Healthier turf / Stronger root system (as told to us by our customers)
100% Vertical Drainage under the entire playing surface
AirDrain creates and helps maintain a constant Gmax for Synthetic Turf fields
Consistent Gmax and Shock Attenuation can reduce the risk of head injury
Helps eliminate standing water / Simplifies maintenance (as told to us by our customers)
Minimal site disturbance / Far less excavation and disposal
Several Installation days are saved over a gravel installation
An AirDrain System sand profile creates its own perched water table without peat moss or clay
