100% Post Manufactured Content
Recycled
The AirDrain GeoGrid is made of 100% post-manufactured material, so you can feel good about helping the planet while adding valuable LEED Points to your project. We also add an impact modifier for incredible strength and superior performance in extreme heat and cold – on top of the already durable AirDrain design.
AirDrain Co-Polymer with an Impact Modifier Performance and Temperature Durability
Attached you will find the specification of the resin used to produce both the 32 x 32 and the 32 x 18 Geo cells. This material is a co-polymer polypropylene that is 100% recycled resin. In order to be able to produce a consistent recycled resin a PIR (post industrial resin) is used for the base resin. This is the only way to produce a consistent material as opposed to a PCR (post consumer resin) which is dependent on the consumer to supply a consistent material. Using the PIR as a base resin 3% carbon black is added to insure good UV stabilization and metallocene (an ethylene base material) is used as an impact modifier.
Impact Modifier
The impact modifier is added in an amount to achieve a 10.0 Notched Izod Impact which comfortably qualifies this material as a NO BREAK material (4.0 and greater are normally considered no break material). The AirDrain resin offers an advantage over many ethylene and HDPE products since the AirDrain resin is often superior when it comes to pliability, warping and internal stress related issues. Referring to the attached specification sheet you will notice that all testing is done to specific ASTM Standards.
Resin Blends
AirDrain’s blend of resins gives it the ability to perform in extreme temperatures. AirDrain does not need a temperature above 50 degrees Fahrenheit to be installed or warmed in the sun to be pliable on site for install. In addition, AirDrain’s unique resin blend also helps prevent breakage and cracking in extreme temperatures. Giving it the ability to withstand repeated freeze thaw cycles.
Airfield posts its resin content and performance values with ASTM test methods and guide lines to measure the properties of our grid.
Proper Sequencing and Orientation of
AirDrain GeoCell Panels for Rapid Installation
Pallet Staging: AirDrain pallets cover approximately 798 sqft. per pallet and should be staged accordingly within the installation area so that you minimize the amount of time to stage the AirDrain grid along the install lines across the project. Typically placing the AirDrain every 65 feet across and 15-20 feet back from each other. (Call AirField with questions that you might have about proper staging and installation.)
All Installations must start in the Top Left Corner of the Field and work Left to Right to be installed properly.
- Orientate the AirDrain GeoCell materials with the integral indicator tab to the panel’s bottom left corner (painted yellow). Install the AirDrain units by placing units with the connectors and platforms up creating a flat surface for the profile above. If the male connectors do not fall or drop into the female connectors then the orientation is incorrect, please call AirField Systems Immediately at 405-359-3775.
- Install the AirDrain panels across the field in a rowed pattern. Staggering of rows will allow for multiple row completion by a multi-manned crew.
- Once the first row has progressed across the project, start with a second row. Have a person staging the panels in three’s snapped together along the row. The crew can then install the left side of the panel while elevating slightly the top portion ( so the male and female connectors don’t sync ) once the left side has been snapped with a pull along the row direction, the top portion should fall into place and with a bottom vertical pull holding the inside of parts 1 & 3 snap all three parts in place.
- AirDrain panels can be shaped to individual field areas as needed with appropriate cutting device. If a typical field is installed correctly there should only be two sides that would need to be trimmed.
- If only a few parts need to be trimmed, use tin snips.
- If many parts require trimming, set up a table and use a circular saw with a no melt, plastic cutting saw blade.

AirDrain Golf Bunker Design
The Greens Country Club in Oklahoma City chose AirField Systems simple Bunker Renovation that was completed with minimal install time and should drain perfectly for many years to come. This golf bunker design can be installed by the existing course grounds crew at your own pace drastically reducing the overall cost of the installs, making it a design that all courses can afford. By raising the sand profile an inch across the entire floor bringing gravity into play in draining the bunker. Effectively making the entire floor of the bunker a drain. The filter fabric and grid is only on the floor of the bunker.
To answer the debate of clogging geotextiles/filter fabrics see the Final Report form the 5 year Study at www.usga.org. Although with the AirDrain Bunker System the entire floor of the bunker is a drain, so even if a few feet of the bunker did clog over a 15 year span you would have the remaining portion to allow for optimal drainage by being able to go vertically through the profile.

Update 5/8/14
Superintendent text: Rained 1.5″ last night bunkers drained excellent and didn’t washout!
Bellerive Country Club host to the 100th PGA Championship, in August of 2018 installed this 7,600 sqft.
practice golf green on their Championship Course. They were very pleased with the AirDrain System for Golf Courses and how quickly and easily it was installed.
After reviewing the findings of the “Comparison of Putting Greens Constructed with AirField Systems and
USGA Design“ (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, AirField Systems and the United States Golf Association) they decided to utilize the AirDrain System for Golf Greens for this project. Click here to see An Alternative to the Gravel in USGA Putting Greens.
