The plastic blind drain, internationally known as geocomposite drainage system (GDS) and also known as three-dimensional drainage board or water drain and collection culvert material in civil engineering, is a kind of three-dimensional porous material produced through heating and melting the thermoplastic synthetic resin and then squeezed to have fiber filaments through the sprayer nozzle and then laminated together and after that welding of the joints. With geotextile fabric wrapped on the main body used as filtering membrane, the product is available with four structure types including porous rectangular type, hollow rectangular type, porous circular type and hollow circular type with different sizes.
