Application of HDPE Geomembrane

Q:Are geomembranes resistant to punctures from human activities?: Yes, geomembranes are generally designed to be resistant to punctures from human activities. They are made from durable materials such as high-density polyethylene (HDPE), which have excellent puncture resistance. However, the level of resistance may vary depending on the specific type and thickness of the geomembrane used.

Q:What are the differences of seepage-proof geomembrane and impervious geotextile?: It is generally recognized that as the geotextile is seepage-proof. The main indicator for performance appraisal is permeability?coefficient. The permeability?coefficient of geotextile is higher than that of common plain soil, namely 0.01 to 0.001. Permeable complex made of the compound of geotextile, rubber, asphalt, and plastic has a better seepage-proof performance which is 10 times more effective. Composite of waterproof roll materials such as SBS, polyethylene, PVC, EVA (standard name geomembrane) combines with seepage-proof geomembrane or composite geo-membrane. And composite white geotextile as a protector covers the outside of them. This is impervious geotextile. There is no big difference between them in essence.

Q:How do geomembranes contribute to stormwater detention and retention systems?: Geomembranes contribute to stormwater detention and retention systems by acting as a barrier to prevent water from infiltrating the ground. They are used to line storage ponds, basins, or underground tanks, creating a watertight seal that prevents the water from seeping into the soil. This helps in detaining and retaining stormwater, allowing for its controlled release or gradual infiltration, reducing the risk of flooding, and protecting the surrounding environment from potential contamination.

Q:Can geomembranes be used in stormwater retention ponds?: Yes, geomembranes can be used in stormwater retention ponds. They are often installed as liners to prevent seepage and leakage of stormwater into the ground, ensuring the pond functions effectively in retaining and managing stormwater.

Q:Can geomembranes be customized for specific applications?: Yes, geomembranes can be customized for specific applications. They can be designed and fabricated with specific materials, thicknesses, and properties to meet the specific requirements of various applications such as waste containment, water conservation, mining, and agriculture.

Q:How do geomembranes perform in high-pressure liquid containment applications?: Geomembranes perform well in high-pressure liquid containment applications. They are designed to have high tensile strength and puncture resistance, allowing them to withstand the pressure exerted by liquids. Additionally, geomembranes have excellent chemical resistance, ensuring that they can effectively contain various liquids without degradation.

Q:What is the coated glass stick membrane?: Coated glass is cheap, but the function of which is not as much as that of film glass. Coated glass not only can protect privacy, but film glass not only can protect privacy but also has functions of heat insulation, anti-explosion, ultraviolet rejection (Heat insulation function can play an air-conditioning role which saves on electricity bills. Anti-explosion function can prevent broken glass from hurting families for it will stick together when the glass is broken and splashed. Ultraviolet rejection function can protect our skin, and prevent furniture and curtains from fading). On the other hand, stick membrane can play a decorative role, there is no glare when seeing through glass with stick membrane (there is eye strain and glare when seeing through glass with no stick membrane). While the film glass is not like that.

Q:How do geomembranes provide containment?: Geomembranes provide containment by creating a barrier that prevents the migration of fluids, gases, or solids. They are made from synthetic materials with high impermeability and are installed as liners or covers in various applications such as landfills, ponds, and mining sites. The geomembrane's ability to resist punctures, tears, and chemical degradation ensures that hazardous substances are contained within the designated area, protecting the environment and human health.

Q:How do geomembranes contribute to reservoir lining?: Geomembranes contribute to reservoir lining by providing a durable and impermeable barrier that prevents water seepage and leakage. They help in maintaining the water level, preventing contamination, and reducing evaporation. Additionally, geomembranes offer protection against chemical corrosion and erosion, ensuring the longevity and structural integrity of the reservoir.

Q:Why geomembrane is necessary in modern construction?: It depends on what it is applied in. Geomembrane can be used in seepage-proof.
