OSO Composite Geonet Drainage System consists of a layer of geonet bonded or wrapped between two layers of geotextile.
The core geonet is designed with a three dimensional structure, which provides excellent compressive creep resistance and a great flow capacity. Two porous and tough geotextiles serve separation and filtration functions, and also protect the geonet. The unique multi-layered design makes the product an efficient drainage and reinforcement system.
Applications
Drainage system for highways, railways, tunnels, underground structures, retaining walls, etc.
Roadbed reinforcement, slope protection, sand dune fixation, gabion groins
Gardens, sports fields, etc.
