Product Description

Tri-dimension composite genet for drainage is a new type of geosynthetics.

Its made of atri-dimension geonet coated with geotextile on both sides. Network core consists of a tri-dimension

thick vertical rib, and a rip on top and bottom .

It can drain underground water quickly, also there is a protection system,which can block the capillary water under high load. At the same time, it can also reinforce and isolate of foundation.


Product Uses


1,Landfill drainage;

2, Roadbed and road drainage; 

3,Railway drainage, tunnel drainage, underground structure drainage. 
4,The retaining back wall drainage, 

5,gardens and sports grounds drainage





Excellent drainage function, can bear long time hige press load

High tensile and shear strength

Reduce the rate geotextile embedding into the core of geonet, can protect long time stable water conductivity

Tri-dimension composite geonet for drainage can bear more than kpa compression load

Its anti-compression capacity is much larger than common geonet for drainage.

Q:What are the geogrids?
Geogrids are 2D latticed grids or three-dimensional screen grids made from high-molecular polymers like polypropylene and PVC (polyvinyl chloride) by thermoforming or mould pressing. They are used in the field of civil engineering.
Q:Geomembrane and geotextile construction scheme
Shallow water lotus root planting technology has become the most water and fertilizer saving method after a few years of development. In order to break through the restricting bottleneck, cropping pattern with the best economic benefits, the most convenient management. Especially suitable for water-deficient area!
Q:How is the heating performance of the electrothermal film?
The heat conversion rate of electrothermal film or electric heater is relatively low and easy to cause desiccation. I think the heat conversion rate of the oil filled radiator is the highest. Now there is a box that can contain water to humidify the air in the new version of the oil filled radiator.
Q:Is the notebook protective film good?
The film for the computer casing can be pasted and it won't produce any bad effect. But the film for the keyboard will, so it is better to tear off the film when you use the keyboard. You can learn about the film for computer casing in my zone where there is much knowlege about it. The film for computer casing has many requirements. It needs special colloid material with good quality, and requires that it can be peeled off after pasting with no residue left and no harm to the notebook for many kinds of film can't be peeled off when put up. Besides, the most important point is that if all the computer casing films are of the same pattern, there will be no fun at all. So you need to customize a personal and fashionable pattern you like.
Q:What are the advantages of high density polyethylene HDPE geomembrane ?
Seamless sweat soldering is ok, water proof anticorrosion, long service life.
Q:How many square meters of geomembrane is checked at a time?
Geomembrane category HDPE geomembrane, LDPE geomembrane, EVA geomembrane, PVC geomembrane, matte geomembrane and other composite geomembrane products are mainly used in civil engineering dams, reservoirs, highways, railways, construction and industrial pollution waste, waste water seepage-proof treatment, etc., which takes the woven fabric as substrate and is composed by monolayer or multi-layer plastic film of the same kind impermeable material main products: The price of cloth membrane, two cloth membrane kind of geomembrane is generally around 11000-13000yuan/ton geomembrane is calculated by product specification or thickness
Q:Does the lower geotextile of composite geomembrane need seaming?
Yes, but the operation is more troublesome.
Q:Generally, how many welding rods are needed when welding the impoted geomembrane of ten thousand square meters?
If the construction surface is flat and open with few turns and dead angles, then the welding rods will be saved. The creeping welding machine will not use welding rods on the flat surface. The welding rod is used in uneven surface on which creeping welding machine can not be used.
Q:The physical properties of HDPE geomembrane
It has the following physical properties: ① excellent chemical resistance (corrosion resistance); ② outstanding resistance to stress cracking (ESCR); ③ the lowest permeability; ④ excellent UV resistance; ⑤ stable resistance to low temperature embrittlement;
Q:How to remove the film on the stainless steel film faced plywood?
There are two methods to remove it completely. 1 You can heat it, dry it and tear it with a electric hair dryer. 2 you can smear it with a cloth dipped in acetic ether (a chemical solvent that specifically dissolves the protective film glue), but it should be noted that the stainless steel surface should be cleaned with water in time after the film is torn off.
