Also known as a three-dimensional geomat, it is a new type of civil engineering material primarily used for vegetation stabilization and slope protection. It is a three-dimensional mesh pad with a loose and flexible texture, leaving 90% of the space to be filled with soil, gravel, and fine stones. Plant roots can grow through it comfortably, neatly, and evenly. The matured turf firmly integrates the mesh pad, turf, and soil surface, forming a robust green composite protective layer. Application examples demonstrate that three-dimensional vegetation mesh slope protection is highly beneficial for slope stability and offers excellent protective effects.
