Introduction of LDPE Geomembrane:
Geomembrane including LDPE, LLDPE, HDPE, EVA, ECB and PVC geomembrane.
Application of LDPE Geomembrane:
---Prevent leakage disposal in waste burying field, waste water, or waste dregs disposing field.
River bank, lake dam, mine remaining, reservoir, tunnel, liquid storage pool(pit, mine)
Preventing leakage of subway, basement, tunnel, holes
Anti-slot leakage in roadbed and other groundsill
The plan direction laying of dam, the vertical direction laying for groundsill, used in the construction fence and waste material field.
Used in seawater or freshwater feed field.
Used in groundsill of road, highway, railway and waterproof layer of swelling clay and wet collapsed loess.
Preventing leakage on rooftop

- Q:Does thermal insulation glass need to stick membrane ?
- Car film advantages: 1, reduce dazzle and glare to make driver feel more comfortable; 2, block 99% harmful ultraviolet rays; 3, reduce air conditioning load and improve fuel efficiency; 4, do not impair driving vision during night; 5, help to fix broken glass in accident; 6, prevent explosion and guard against theft.
- Q:whether the sound insulation membrane of windows and door is useful?
- Doors and windows soundproof membrane effect is still very good, under normal circumstances, a qualified good installment doors and windows soundproofed reasonable film thickness is sufficient to achieve a compliant body sound insulation, windows and doors sound insulation membrane is to prevent noise intrusion, you can add a layer of tight sound insulation film or a relatively strong absorption of cotton close to the transport routes. In order to prevent TV, stereo, piano disturbing your neighbors, you can add ultra-thin glass absorption cotton in television, audio background wall, the effect is very good.
- Q:How to pave the electrothermal film?
- Attention should be paid to several aspects when paving ceramics on electrothermal films: first, is waterproof insulation should deal be well prepared; second, the concrete used to pave ceramics should not be too thick. The thickness should be controlled within 50mm (the thickness of concrete and ceramics
- Q:is geomembrane usually produced abroad?
- China is the largest producer of geomembrane. why you want to import Like HDPE high density polyethylene geomembrane. The new materials are made according to export standards. national standards divides into two standards.
- Q:Geomembrane design
- Q:What is the material of the decorative film ?
- Q:How does the insulation effect of the heat of the glass film?
- It is not very good, and the anti ultraviolet is proposed.
- Q:What are the advantages using foil in construction?
- Architectural glass film benefits include: 1, more economical. Both steel and transparent glass or colored glass paste heat reflective film than the replacement of heat-reflective glass to save 50% of the total cost, the remaining cases by analogy, for example: Original ordinary insulating glass were upgraded to a hollow heat-reflective coated glass or hollow Low-E coated glass paste after heat-reflective film or Low-E film. 2, more efficient. the window film is easy to operate, use of time shorter than changing a new window. 3, more environmentally friendly. Replace the window will produce large amounts of construction waste, transport and landfill costs will increase, and the glass film can be used both to heat and safety upgrades. But also to prevent indoor carpet, curtains, fabrics and paint fade, the effective protection of indoor furniture, computers and other office equipment, extending its life. 4, more secure. General insulation film also has some security enhancements, along with the clip (plastic) layer of glass fragments stick holding performance, its safety is better than glass, security professional security film stronger. 5, more healthy. Window film installation gel containing UV (ultraviolet) absorber, can block 98% -99% of UV rays. 6, more light. If you change a hollow glass, plus two glass hollow part of the total weight of the double or more, will greatly increase the building load.
- Q:Which one is better, electric heating film and carbon crystal?
- First of all the inside of electric heat mold is all wire. We are taught in high school physics that electromagnetic radiation is powerful if there are a lot of electric circle. Can you feel safe on thinking that your house is surrounded by electromagnetic radiation,
geotech, is a well-known enterprise in the research, design, and devolopment of rail and road tunnels rubber waterproofing membrane products.
Since 1997 we has been engaged in the service work of rubber products and waterproofing roll roofing for
construction of railways, highways, bridges, tunnels and other projects. Rich experience of product development, technology,manufacture, quality control and after-sales has been accumulated.
