Geomembrane is a kind of waterproof material with basic raw material of high molecular polymer. It is mainly divided into LDPE geomembrane, HDPE geomembrane, and all kinds of composite geomembrane.
Complete variety of specifications of width and thickness. Thickness: 0.2-2.0mm.
Excellent environmental stress resistant cracking performance.
Excellent performance of chemical erosion resistance.
Big scope of application temperature and long service life .
Low Permeability :HDPE lining systems are secure because leachate does not penetrate them Methane gas will not escape from the HDPE cover system .and rainwater will not infiltrate.
Chemical Resistance:HDPE ,resistant to a wide range of chemicals ,is not threatened by typical solid or hazardous waste leachates.It is also suitable for sludge and secondary containment around chemical storage facilities
Ultraviolet Resistance:HDPE's resistance to UV exposure is further enhanced by the addition of carbon black .Additionally ,with the absence of plasticizers ,volatilization is not a problem

- Q: New national standard for polyethylene geomembrane
- Polyethylene geomembrane new national standard is GB / T-2011. The new standard is released on the date of 2011-12-30. The new standard implementation date is 2012-09-01. The new standard increases the single rough surface geomembrane and double rough Surface geomembrane, the abolition of the EVA geomembrane.
- Q: How to use geosynthetics impervious device?
- 1. Set pressure. Press the set button "back" and the button "＞" after powering on the device. Press the button “+”and“--”, then set pressure. After that press the button "back" to save it. After setting the lower limit value, press the set button to exit. 2. Clear the time setting. Redo the test and continue pressing the "--" button. The time value will be reset to 0 after 10 seconds. Don't press the button during the working time. 3. Check the time. Press the "--" button. The time value accurate to seconds will be shown on the screen. After 30 seconds, pressure value will be shown on the screen again. 4. Adjust to zero. If the pressure setting can't return to zero when the device is powered on without being applied pressure, you can press the reset button once. If the device is under pressure, release the pressure before pressing the button. 5. Open water injection cover plate. Add pure water until the water tank is full. Apply pressure and open pressure regulating valve to let water flow to chassis of high pressure cabin until the water begins to overflow. 6. Put the sample on the net plane of water collectormanifold smoothly. Let the excess water drain away to ensure that there are no bubbles in sample clamping device. Close the perforated plate and fix the sample evenly.
- Q: What are the differences of geocells and geogrids?
- Geocells have three-dimensional celllike structure made from reinforced HDPE sheets by strength welding. They are usually made by ultrasonic pin type welding. Sometimes there are holes punched on the membranes for the requirements of engineering. They are elastic and shrinkable when transported. They can be stretched into shape of net. When geogrids are filled with bulky material like soil, rubble and concrete, a structure with high sidewise restraint and high rigidity forms. They have light weight, good wear resistance, chemical stability, photooxidation resistance, aging resistance, acid resistance and alkali resistance. They can be used in different soil conditions like soil and desert. They can be used to reinforce the roadbeds of highways and railways. They can be used to protect slopes and construct mixed barricades. 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 applied in the field of civil engineering. Geogrids are often used as tendon material of reinforced soil structure or of other composite materials. Geogrids can be divided into four categories, namely plastic geogrid, steel geogrid, glass fiber geogrid and polyester warp knitting dacron geogrid. Geogrids are used to reinforce all kinds of dams, roadbeds, side slopes, tunnel walls, and permanent bases of large airports, parking lots, wharfs, freight yards, etc. Geogrids are easy to install. They are time saving, labor saving with shorter construction time and lower maintenance cost.
- Q: What is the cost of a geomembrane installation?
- The cost of a geomembrane installation can vary depending on various factors such as the size of the area, type of geomembrane material used, site conditions, and labor costs. It is best to consult with a professional installer or contractor to get an accurate estimate for your specific project.
- Q: How do geomembranes improve water efficiency in golf course irrigation?
- Geomembranes improve water efficiency in golf course irrigation by acting as a barrier that prevents water from seeping into the ground and instead directs it towards the desired areas. This helps to minimize water loss through evaporation and deep percolation, ensuring that the water is effectively utilized for irrigation purposes. Additionally, geomembranes can also help in managing water runoff and preventing soil erosion, further enhancing water efficiency on golf courses.
- Q: What is the installation technology of soft membrane?
- When installing the soft membrane, the first is to install the four angles of A, B, C, D, then the diagonal pull point installation, finally all installation. The installation sequence: 1. Before the entering of the soft film smallpox, the site must be electrified and without construction waste. 2. The deal with the bottom of the piamater ceiling should be fit for the installation conditions, such as the installation of the steel and so on; it must be cleaned. 3. All the installation of the lights must be according to the requirement of us. We should ensure all of the circuit to be electrified. If there are any lamp not lighting up before installing the soft film, it should be adjusted and repaced in time. The interior hidden lights should be painted with white paints so as to get a better effect. 4. The air conditioning and fire pipes must be arranged in advance and debug to keep it operating well. After the installation of the air inlet, spray head, and smoke sensor, all of them should meet the requirements of us. 5. After the installation of the piamater ceiling is completed, for example, the paint should repair the gypsum board and should not touch the soft film smallpox.
- Q: How do geomembranes contribute to the preservation of coastal ecosystems?
- Geomembranes contribute to the preservation of coastal ecosystems by providing a protective barrier against erosion and preventing the contamination of water bodies. They help to stabilize the coastline by reducing wave energy and preventing sediment erosion, which in turn protects the delicate habitats and ecosystems along the coast. Additionally, geomembranes are used in the construction of artificial wetlands and other coastal restoration projects, creating suitable habitats for marine life and promoting biodiversity. Overall, geomembranes play a crucial role in safeguarding coastal ecosystems and ensuring their long-term preservation.
- Q: What is the cost of membrane structure?
- Because of its cost is too high, the general building construction will consider about the cost and performance, it is very rare to choose this kind of film material, and the number of the producer of this membrane abroad is very few.
- Q: How are geomembranes tested for tear resistance?
- Geomembranes are typically tested for tear resistance using a standardized test method called the Elmendorf Tear Test. This test involves cutting a specific shape in the geomembrane sample and subjecting it to a controlled force, measuring the force required to propagate the tear. The tear resistance of the geomembrane is determined by the amount of force required to tear through the material.
