Product Description

3D Composite Drainage Net

Three-dimensional composite drainage network is a new type of geosynthetic material. The structure is a three-dimensional geotechnical core, and both sides are adhered with needle-punched non-woven earthwork fabrics. The three-dimensional geotextile core includes a thick vertical rib and a beveled rib at the top and bottom.The groundwater that can be quickly drained from the road itself has a pore maintenance system that can block capillary water at high loads. At the same time, it can also play a role in isolation and foundation reinforcement, is a new type of geosynthetics. Three-dimensional composite drainage network made by the unique three-dimensional geotextile double-sided adhesive geotextile. Combined with geotextile filter effect and geotextile drainage and protection, to provide a complete "filter - drainage - protection" effect.

3D Composite Dewatering Network :

1.It is laid between foundation and base, which is used to discharge water between foundation and base, block capillary water and effectively combine it into the marginal drainage system.This structure automatically shortens the foundation drainage, drainage time significantly shorter, and can make the decrease in the number of the use of the material selection of foundation can be used with more fine material, low permeability of materials.Can extend the life of the road.

2.In the base layer laying three-dimensional composite drainage network to prevent the base of fine material into the ground floor, that is, play a role in isolation. Aggregate grass will enter the upper part of the geonet in a limited degree. In this way, the composite geotextile network also has a potential to limit the lateral movement of the aggregate base, in this way, its role is similar to the strengthening of the Geogrid. In general, the tensile strength and rigidity of the composite geotechnical drainage network is superior to many geogrids for foundation reinforcement, and this restriction will improve the supporting capacity of the foundation.

3.Road aging, cracks formed, most of the rain will enter the section. In this case, the three-dimensional composite drainage network directly laying under the road, instead of drainage of the foundation. The three-dimensional composite drainage network can be collected before the water enters the foundation / sub-base. But also in the three-dimensional composite drainage network at the bottom of a layer of film, to further prevent the water into the foundation. Whether it is for rigid roads or flexible road systems, this structure can extend the life of the road.

product usage

Mainly used for railway, highway, tunnel, municipal engineering, reservoirs, slope protection and other drainage works in a significant effect.

drainage net


1. Drainage strong (equivalent to one meter thick gravel drainage).

2. High tensile strength.

3. To reduce the probability of geotextile embedded core, to maintain long-term stability of the drainage.

4. Long-term high-pressure load (can withstand about 3000Ka compression load).

5. Corrosion-resistant, acid and alkali, long service life.

6. Construction convenience, shorten the construction period, reduce costs.

Seam and lap of three - dimensional composite drainage network

1, adjust the direction of geosynthetics, so that the length of the material roll perpendicular to the road.

2, composite geotechnical drainage network must be terminated, adjacent geotextile geotextile along the material roll lap.

3, the adjacent geotextile material of the geotextile core with white or yellow plastic buckle or polymer tape connected to connect the material roll. Along the length of the material roll, every 3 feet with a tape connected once.

4, The direction of the geotextile lap to overlap with the direction of packing. If the geotextile material is laid between the foundation / base layer and the base layer, continuous wedge welding, flat welding or stitching shall be carried out so that the upper layer of the overlapped geotextile is fixed. If stitching, it is recommended to use a flat seam method or a general seam method to achieve the minimum requirement for pin length.
