The geocell is made of 1.5 mm thick polyethylene (HDPE) tape, bellows wrapped in a transport container. The slots in the open-ended tip can be filled with any fine-textured material, usually gravel or soil.
The height of the geo-ridge is chosen according to the slope gradient – the steeper the slope, the higher the geo-ridge should be. In general, a 10cm – 15cm high geogrid is sufficient.
