The use of hdpe geocells allows materials to be collected on site or nearby, and materials that are not normally available can also be used, which can significantly reduce material purchase and transportation costs. Since the hdpe geocell chamber is mostly filled with non-adhesive materials such as crushed stone and gravel, and the hdpe geocell reinforcement layer is also a horizontal drainage channel, it can speed up the dissipation of pore water pressure during the consolidation of saturated soil and accelerate soil consolidation. In short, hdpe geocells have the comprehensive effects of adjusting cushion layers, reinforcement, drainage, stress and deformation, and improving the anti-seepage capacity of soil.
