Large Flow Plastic Drainage Ditch High Compression Plastic Blind Ditch For Retaining Wall And Landfill Engineering
Plastic Drainage Ditch is a high-performance underground drainage system made from thermoplastic resin core structures wrapped with permeable geotextile fabric. The product is designed to replace traditional stone blind ditch systems and provide efficient long-term drainage solutions for civil engineering projects.
The internal drainage core forms a stable three-dimensional network structure with high porosity and excellent compressive performance. The outer filter fabric prevents fine soil particles from entering the drainage channel while allowing water to pass freely.
This integrated drainage system combines filtration, water collection, and rapid discharge functions in one lightweight product. Due to its excellent durability and flexibility, Plastic Drainage Ditch is suitable for complex underground drainage environments and soft soil conditions.
The product is extensively applied in retaining wall drainage, landfill projects, railway subgrades, municipal engineering, airport drainage systems, slope protection, and tunnel waterproof engineering.
