EnviroGrid ® is a three-dimensional cellular confinement system that provides a cost effective and sustainable solution to erosion control problems and soil stabilization needs. The geocell confines and strengthens infill material and significantly reduces the amount of infill material needed, allowing for the use of local aggregate. Made with ultrasonically welded HDPE virgin resin, EnviroGrid ® is designed for long term use in critical applications such as base stabilization, slope erosion, channel protection and retaining walls. The first cellular confinement system was developed by the U.S. Army Corps of Engineers for its use in Desert Storm in order to construct roads over soft ground. Since 1990, Geo Products has manufactured the EnviroGrid ® Geocell in the USA in its ISO 9001 certified facility with superior quality control standards. Geo Products specializes in offering a range of high quality polyethylene products, tailored to your needs. The EnviroGrid ® Geocell is manufactured in three different cell sizes or apertures with four different cell heights. The three cell apertures are EGA 20, EGA 30, and EGA 40, all offered in cell heights of 3", 4", 6", and 8". EnviroGrid is shipped in flat panels and expanded into the 3-D honeycomb structure. The standard EnviroGrid section is manufactured from 58 strips of HDPE ultrasonically welded together, resulting in a section length of 29 cells, with each strip being the approved width and 142 inches in length.

Utility Access Roads

Location:Tampa, Florida, USA

OVERVIEW Tampa Bay Water works needed to build pads and roads to service over 15 wells throughout its preserve. The solution needed to not only minimally disturb the preserve, but still be durable enough to withstand utility vehicles while being accessible throughout the year. The solution required being built atop of the native sandy soils that are present in Florida. SOLUTION Chosen for its strength and durability when confining lesser-quality aggregate material, EnviroGrid® was the chosen solution to build the well pads and 3.5 miles of roads on top of the native Florida sands. EnviroGrid® provided 3.5x the strength of the aggregate by itself while also creating a mattress layer on top of the native sands. This reduced the amount of pressure the subbase would endure. After the EnviroGrid® was installed and filled, a 2” top of limestone was added. PUT TO THE TEST EnviroGrid’s performance was put to the ultimate test when Tropical Storm Fred hit the coast of Florida during the summer of 2021 and left behind 2' of water in some areas across the preserve. As shown in the photo to the right, the roads were still accessible by vehicles after the storm. CONCLUSION EnviroGrid® Geocell adds strength to poor quality aggregates and reduces the amount of aggregate needed for a site. By creating a firm mattress layer that reduces the amount of pressure on the subbase layer, EnviroGrid® provides a long term solution for access roads
