Composite drainage network has a good protective effect besides drainage in places such as laying foundations.
3D Composite Drainage Network
Three dimensional composites drainage network is a new type of drainage geotextile material. It is one three-dimension geonet composited with two needle-punched non-woven geotextiles. Double sided adhesive seepage geotextiles form a "filtration-drainage - ventilation - protection" overall performance, and can replace the traditional sand and gravel. Its pure maintenance system can drain underground water quickly, block the capillary water under high load in construction, keep certain thickness and provide good water conductivity property.It also play the role of isolation and foundation reinforcement.

(1) Geonet is mainly used in soft foundation treatment, subgrade reinforcement, slope protection, abutment reinforcement, coastal slope protection, reservoir bottom reinforcement and other projects. Laying geotextile on the side slope of the road can prevent the rock from falling off and harm to people or vehicles; Wrapping the ballast with geotextile can prevent the loss of ballast and subgrade deformation, and improve the stability of subgrade. Laying geonet can strengthen the pavement and prevent the development of reflective cracks; Geonet, as a reinforcing material in the filling of retaining wall, can disperse soil stress, limit lateral displacement and enhance stability. The gabion made of geotextile is used to protect the surface of dams and rocks, which can prevent erosion, landslide and soil erosion. (2) Use: Used for subgrade reinforcement, so that granular filler and grid are locked together to form a stable plane, prevent the filler from sinking, and disperse the vertical load; Multi-layer reinforcement can be used in areas with poor geographical conditions. A, prevent roadbed cracks, avoid landslides. B. Enhance the slope of foundation and dam, improve the stability of subgrade and reduce the occupied area; C, can bear heavy load; D, shorten the construction period; E, CE131 is used for pavement reinforcement, which makes the grid and pavement materials fuse together, which can effectively disperse and transfer loads, prevent pavement cracks, enhance pavement stability and prevent cracks; Can bear large variable load; Can prevent pavement cracks caused by frost boiling; It can reduce the amount of pavement materials and speed up the construction speed.
