Geocell, Cellular Confinement System - What is It?
Geocell, also known as a cellular confinement system, is a 3-D expandable, panel made with high-density polyethylene (HDPE) plastic. When expanded, the panel reveals individual openings, or cells, where material such as gravel, sand, recycled concrete and more, can be placed. The benefit of using geocell is that it confines and strengthens the gravel, which results in less ruts, holes, and loss of material over time. The panel does this by spreading the weight of the load laterally, creating a mattress effect that keeps the gravel from being pushed into the ground.
Is This a New Concept? Why Haven't I Heard of Geocell?
The concept of cellular confinement system grids were first introduced by the US Army Corps of Engineers in the 1970's. It was used to create durable roads and airstrips over soft soils that could withstand the heavy loads of military vehicular traffic, even in rainy conditions. In the 1990's, manufacturers in the United States began manufacturing the system, but with HDPE (high-density polyethylene), a type of plastic that was chosen based on its superior quality and durability characteristics.
