The HDPE geocells are designed to contain and confine the fill materials within the cells, preventing soil erosion and promoting load distribution. They are commonly used in applications such as road and railway construction, slope protection, retaining walls, and load support.

A typical honeycomb restraint system involves the use of geosynthetic materials, such as HDPE strips or a novel polymer alloy (NPA), which are ultrasonically welded to form the honeycomb structure. This structure is then filled with various materials, including sand, soil, rock, gravel, or even concrete, depending on the specific project requirements. The infill material provides additional stability and load-bearing capacity to the geocell system.
