Innovative Composite Drainage Net Achieves “Three-in-One” Functionality, Pioneering a New Era in Geosynthetics

As infrastructure projects place increasing demands on drainage, protection, and reinforcement, a groundbreaking geosynthetic material—the Composite Drainage Net—has emerged, offering a powerful solution that combines filtration, drainage, and structural support in one system. This innovation is setting new standards in geotechnical engineering.

The composite drainage net is engineered from a three-dimensional geomesh core, laminated with needle-punched non-woven geotextiles on both sides. This unique structure merges the filtration performance of geotextiles with the drainage efficiency and reinforcement protection of the geomesh, delivering a comprehensive “filtration-drainage-protection” effect.

At the heart of this material is a robust geomesh core featuring a thick vertical rib and angled ribs at the top and bottom. This design allows for rapid groundwater discharge from roadbeds and forms a reliable pore-maintenance system that effectively blocks capillary water, even under high load conditions.

Thanks to its high compressive strength, the composite drainage net retains considerable thickness throughout its service life, ensuring excellent water conductivity and long-term performance. With its advanced multi-functional design, it is poised to become a vital component in modern geotechnical and civil engineering projects worldwide.
