What is Geofill Construction?
Geofill construction is an innovative technique that involves the placement of a mixture of soil and polymer materials in a geogrid structure that provides reinforcement and stability to highways, bridges, embankments, and other structures. It is a cost-effective solution for soil stabilization, structural support, and erosion control. Geofill construction is also known as cellular confinement technology or geocell.
How Geofill Construction Works?
Geofill construction is based on the principle of cellular confinement technology. It involves the use of a geogrid structure made of high-density polyethylene (HDPE) panels that are connected together to form a honeycomb-like structure. The panels are then filled with a mixture of soil and polymer materials. The geogrid structure prevents the soil from spreading, and the polymer materials increase the bearing capacity and improve the load-transfer mechanism of the soil. This results in an overall increase in the strength and stability of the structure.
