Product introduction: Composite drainage network (also known as three-dimensional composite drainage network, tunnel discharge water plate, discharge water plate) is composed of a three-dimensional structure of plastic mesh double-sided adhesive permeable geotextile, which can replace traditional sand and gravel layers. It is mainly used for drainage in landfills, roadbeds, and tunnel walls. In transportation infrastructure such as railways and highways, the service life of the project is closely related to its own drainage system, and geosynthetic materials are an important component of the drainage system.

Product specifications: Mesh core thickness 4mm-8mm; Width of 2m-6m; The weight of geotextiles is generally 200g per layer; the length is based on user requirements.

Application scope: It is mainly used in drainage projects such as railways, highways, tunnels, municipal engineering, reservoirs, and slope protection, and has a good effect.

Execution standard: CJ/T 452-2014 "Geotechnical Drainage Network for Landfill Sites"
