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: What are the differences of seepage-proof geomembrane and polypropylene fiber impervious geotextile?
- Watercourse. The excellent environmental stress cracking resistance of seepage-proof geomembrane enables it to be used in large seepage-proof projects such as landscape lake, impounding reservoir and other projects, the anti-seepage effects are basically same: Toilet waterproofness seepage-proof geomembrane is made of high density polyethylene (HDPE) Tunnels: Reservoir, polypropylene fiber impervious geotextile is made of polypropylene fiber (PP). Polypropylene fiber impervious geotextile has a high friction coefficient which are often used in small buildings. These impermeable materials are both acid- and alkali-resisting.
- Q: Can geomembranes be used in wastewater evaporation ponds?
- Yes, geomembranes can be used in wastewater evaporation ponds. They are often utilized as liners to prevent seepage and leakage of the wastewater into the surrounding soil and groundwater. The geomembrane acts as a barrier, ensuring that the wastewater is contained within the pond and allowing for effective evaporation processes to take place.
- Q: what's the specification of composite geo-membrane?
- Commonly used geomembrane specifications include 150 / 0.2 / 150 300 / 0.3 / 300, etc., they are generally divided into two cloth one membrane and one cloth one membrane, it's usually formed by calendering or thermal compound production process. Geomembrane is generally used for the anti-seepage project, for example, reservoir anti-seepage, reinforcement, roadbed anti-seepage, tunnel anti-seepage, airport anti-seepage and other projects.
- Q: Are geomembranes resistant to frost heave?
- Yes, geomembranes are generally resistant to frost heave. They are designed to be impervious to water and have low permeability, which helps prevent the expansion of ice and subsequent uplift caused by freezing temperatures.
- Q: How do geomembranes provide insulation in roofing systems?
- Geomembranes provide insulation in roofing systems by acting as a barrier between the roof and the external environment. They are made of materials with high thermal resistance, such as PVC or EPDM, which help to reduce heat transfer and maintain a stable temperature within the building. Additionally, geomembranes can be installed with insulation layers underneath, further enhancing their insulating properties by preventing heat loss or gain through the roof.
- Q: How do geomembranes handle ground settlement?
- Geomembranes are designed to handle ground settlement by being flexible and able to conform to the changes in the underlying soil. They can stretch and deform without tearing or losing their integrity, providing a barrier that remains intact even as the ground settles. Additionally, geomembranes can be installed with appropriate anchoring and slope design to accommodate settlement and ensure long-term stability.
- Q: What are the long-term performance expectations for geomembranes?
- The long-term performance expectations for geomembranes include durability and resistance to environmental factors such as UV radiation, temperature variations, and chemical exposure. They are expected to maintain their structural integrity and impermeability for decades, effectively preventing leaks and contamination. However, proper installation, maintenance, and regular inspections are crucial to ensure their longevity and performance over time.
- Q: How do geomembranes help with water storage and containment?
- Geomembranes help with water storage and containment by creating a reliable barrier between the water and the surrounding environment. They are impermeable liners made of synthetic materials that prevent water from seeping into the ground or escaping into nearby areas. This allows for efficient storage and containment of water, reducing the risk of water loss, contamination, and damage to the surrounding ecosystem.
- Q: What are the quality characteristics of HDPE geomembrane?
- 1.Simple construction: It just need to dig poola and do some treatmentg accordingly. It need no concrete cushion layer; 2. Rapid construction: There is no structural concrete curing time; 3. Resistant to base deformation: Because HDPE geomembrane has good elongation at break, it can be resistant to base sedimentation or base deformation; 4. good effect: This is the biggest feature of HDPE geomembrane; 5. easy recovery after use: This is the biggest feature of HDPE geomembrane. After being used, it can be recover as long as to collect it and backfill the pool.
