Waterproof Geomembrane/Liner/ Sheet with China Top Quality

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: Can geomembranes be used in geothermal applications?: Yes, geomembranes can be used in geothermal applications. Geomembranes are impermeable liners that prevent the leakage of fluids and gases. In geothermal applications, they can be used to line the geothermal reservoirs and prevent the loss of heat or the contamination of surrounding soil and groundwater. Additionally, geomembranes can be used as thermal barriers or insulation to enhance the efficiency of geothermal systems.

Q: What is the construction method of geomembrane for planting shallow water lotus?: The bottom of the pond should be cleaned and tamped first, and then the HDPE geomembrane of 0.5 is laid on it. When the geomembrane is laid, patchwork should be avoided ane the edge joint lap width is 15-20 cm which should be welded by a climbing welder. Then you can put nutrition soil and water.

Q: How to paste anti-explosion glass film?: Explosion-proof membrane is generally adhered to the inside of the glass. Before pasting, the glass must be absolutely clean, and the part to be pasted membrane must be repeatedly washed. If there is left any tiny dust on the glass, it will affect the adhesive force of the architectural membrane, for the veneer of the membrane and the glass can only be firmly adhered in the vacuum state.

Q: What is a coated glass?: It is to coat a film on top of the surface of the glass. There are many kinds of coated glass to be chosen.

Q: Characteristics of geomembrane: Geomembrane as a new material, has excellent seepage-proof property, antiseptic property, good chemical stability and features and functions which can be processed according to the actual project needs. Geomembrane has been widely used in dyke, dam , reservoir seepage-proofing in water conservancy engineering, at the same time, geomembrane is also used as seepage-proof, corrosion-proof, leak-proof and moisture-proof materials in areas like channels, impounding reservoir, cesspit, swimming pool, housing construction, underground structures, wasteyard and environmental engineering, etc.

Q: What are the advantages of using geomembranes in canal lining?: The advantages of using geomembranes in canal lining include preventing water seepage, reducing evaporation losses, improving water storage efficiency, minimizing weed growth, and providing long-term durability. Geomembranes act as a barrier, effectively preventing water from infiltrating the canal walls, which helps to conserve water resources. Additionally, they reduce evaporation losses, which is especially important in arid regions. The use of geomembranes also helps to improve water storage efficiency by reducing seepage, ensuring that the maximum amount of water reaches its intended destination. Furthermore, they minimize weed growth, which can clog the canal and hinder water flow. Lastly, geomembranes offer long-term durability, providing a cost-effective solution for canal lining that requires minimal maintenance and repairs.

Q: What is the household colourful film: Color film is a new decorative material, changing the disadvantages of traditional renovation and decoration, such as serious pollution, time-consuming, high cost and multi effects. It has the advantages of clean construction, seamless splicing, that is attached to the housing, monotonous color changed in the twinkling of an eye, you can have a happy mood every day. It has ultra cost performance with high quality and low price, it can save money beyond imagination! Surface stains can be rubbed immediately with non destructive effect. It has 6 years long warranty period and 30 years long service life.

Q: How do geomembranes contribute to erosion control in dam and reservoir construction?: Geomembranes contribute to erosion control in dam and reservoir construction by providing a protective barrier against water seepage and erosion. These impermeable liners are installed along the slopes and base of the dam or reservoir to prevent water from infiltrating into the surrounding soil and causing erosion. By effectively containing the water within the structure, geomembranes minimize the risk of hydraulic pressure and erosion, ensuring the stability and longevity of the dam or reservoir.

Q: What are the characteristics of HDPE geomembrane?: As a new material, geomembrane has excellent anti-seepage effect, corrosion resistance and chemical stability. And it can process features and functionality according to the actual project needs. Geomembrane has been widely used in water conservancy embankment dam , reservoir seepage. At the same time, it has ben widely used as seepage-proof, anti-corrosion, leakage-proof and non-hygroscopic material in channel, impounding reservoir, cesspit, swimming pool, house building, underground structure, wasteyard, environmental engineering, etc.
