The U.S. Army Corps of Engineers developed the first cellular confinement system in the late 1970's as a means to construct roads, airstrips, etc. over soft ground and provide a system that would not be adversely affected by wet weather conditions. They determined that placement of adjacent thin walled sand-filled cells over a soft sub-grade provided significantly greater load/bearing capacity than compacted soil alone.


Of all the various materials tested, high-density polyethylene (HDPE) was found to provide the best combination of strength, service life, and economy.


The EnviroGrid® cellular confinement system has been manufactured since 1990. The first customer was the United States Department of Defense, purchasing 6.4 million square feet of EnviroGrid® for use in various military applications during operation Desert Storm.


Geo Products was licensed by the United States Army Corps of Engineers, the patent holder for the geocell material
