HDPE Geocell Used for slope and embankment protection. When used for slope protection, the unfolded geocell walls form layers of retaining walls, which can greatly alleviate the flow velocity of water and avoid the formation of slope runoff. The geocell can be filled with soil, and grass and shrubs can be planted on top. In the case where vegetation cannot be restored on the original slope, ideal greening effects can still be achieved, which has immeasurable environmental value. In addition, due to its integrity and certain flexibility, the geogrid greatly compensates for the defects such as looseness, collapse, and overhead of the rubble skeleton protection, and is a very ideal geosynthetic material for slope protection with fast construction and low cost.
