100% Post Manufactured Content

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, warpage 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.


Calculating Open Area

Another important aspect of AirDrain is it's ratio of open air to plastic on both the large opening and the small opening sides.  The entire part has 961 square inches of surface area. The large cup has 1.21 square inches of plastic per each cup on the surface and the small cup has 1.14 square inches.  Knowing that it takes 100 cups to make a part, the calculation is simple as to the cups contribution to surface area.  On the large cup side, the connecting links must also be considered while none exist on the small cup side.  Using our electronic model from which the tool was constructed and revised the total surface area on the large opening side is 193.4 square inches for an opening of 79.9 % and on the small surface (no connectors) 88.2%.
