    Technical points
    1, a large volume of geomembrane laying is suitable for mechanical work, a small volume of geomembrane can be laid manually.
    2、The laying direction of the geomembrane should be by the design requirements, and make the least amount of joints, and joint position parallel to the direction of tensile stress.
    3, should not be too tight when laying, and should leave enough margin (about 1.5%) to splice and adapt to temperature changes. It should be paved with pressure and put 1 20-40㎏ sandbag every 2-5 meters at the corners of the membrane to prevent the wind from blowing.
    4、The connection between the geomembrane and surrounding buildings is anchored by expansion bolts and steel plate pressure bars. At the corners, attention should be paid to cutting the geomembrane appropriately to ensure proper connection with the surrounding buildings.
    5、Before welding, do a small sample welding test, according to the test results of the welding equipment adjusted to the state.
    6、When welding, the welding quality should be observed at any time. According to the actual construction situation, adjust the welding equipment to the working condition at any time.
    7, the nodes formed between geomembranes should be T-shaped, not cross-shaped, T-shaped nodes should be used at the base material to make up the scar, the scar size of 300 mm × 300 mm. The right angle of the scar should be rounded.
    8、When there is false welding and leakage welding, the weld must be cut, and the cut part should be patched by a hot melt extrusion welding machine.
    Precautions
    1、Construction personnel must wear non-nailed shoes or rubber-soled shoes, prohibited in the geomembrane arbitrarily stepped on.
    2、After paving the film, the protective layer should be constructed in time to prevent the deformation of the geomembrane caused by heat contraction and the aging of the geomembrane caused by ultraviolet radiation.
    3, prohibit contact with chemical substances that can cause changes in the performance of polyolefin, to avoid permanent deformation of the geomembrane. 4, machinery shall not be directly crushed geomembrane surface.
    Design material selection
    According to the nature of the project, category, application parts, conditions of use, design requirements, etc. to choose the appropriate types and specifications.
    Determine the thickness of the geomembrane according to the strength of the water pressure requirement of engineering design, as well as exposure, burial pressure, climate, service life, and other application conditions.
    Determine the width and length of the geomembrane according to the actual size of the project, area, construction conditions, construction capacity, and the principle of joints during construction.
    When the grass-roots level is a concrete structure, it is appropriate to choose filament non-woven composite geomembrane that can be directly bonded on the cement base.
    Highway application in the seepage control treatment, seepage control in the lower part of the central divider is generally used in one cloth and one membrane 200-300g/m2.

What Role Does Composite Geomembrane Play in Preventing Soil Contamination?
Composite geomembrane play a crucial role in preventing soil contamination by serving as impermeable barriers that isolate hazardous substances from the surrounding environment. In various industrial, commercial, and infrastructure projects, these geomembranes are employed to mitigate the risks associated with soil contamination, safeguarding soil quality and ecosystem health. 
1. Containment of Hazardous Substances:
Composite geomembranes act as robust barriers, preventing the migration of contaminants from anthropogenic sources, such as landfills, industrial sites, and chemical storage facilities, into the underlying soil layers. These geomembranes effectively encapsulate hazardous substances, including heavy metals, organic pollutants, and industrial chemicals, thereby minimizing the risk of soil contamination.
2. Landfill Liners and Caps:
In waste management practices, composite geomembranes are commonly used as liners and caps in engineered landfills to prevent leachate infiltration and soil contamination. By creating impermeable barriers between the waste materials and the underlying soil, these geomembranes mitigate the potential for leachate generation and the release of harmful substances into the surrounding environment.
3. Contaminated Site Remediation:
Composite geomembranes play a pivotal role in the remediation of contaminated sites, such as brownfields and industrial facilities, where soil and groundwater have been impacted by historical pollution. These geomembranes are utilized in containment barriers, capping systems, and soil covers to isolate contaminated soil and prevent further dispersion of pollutants, facilitating the site's restoration and rehabilitation.
4. Protection of Water Resources:
Soil contamination can pose significant risks to water resources, including groundwater, surface water bodies, and drinking water supplies. Composite geomembranes help prevent the infiltration of contaminants into the soil, thereby reducing the potential for groundwater pollution and surface water runoff. 
5. Environmental Restoration Projects:
In ecological restoration initiatives, composite geomembranes are employed to mitigate the impacts of soil contamination on natural habitats and biodiversity. These geomembranes serve as containment barriers in remediation zones, wetland restoration projects, and shoreline stabilization efforts, preventing the spread of pollutants and facilitating ecosystem recovery.
6. Agricultural and Land Management Practices:
Composite geomembranes can be utilized in agricultural and land management practices to prevent soil contamination from agrochemicals, such as pesticides, fertilizers, and herbicides. By creating impermeable barriers between agricultural runoff and the underlying soil, these geomembranes help minimize the leaching of pollutants into the soil profile, protecting soil fertility and crop productivity.
7. Infrastructure Development:
In infrastructure projects, such as transportation corridors, industrial facilities, and urban developments, composite geomembranes are utilized to mitigate the risk of soil contamination from construction activities and infrastructure installations. These geomembranes serve as temporary and permanent containment barriers, preventing the release of construction-related pollutants and preserving soil quality.
8. Regulatory Compliance and Risk Management:
The use of composite geomembranes in soil contamination prevention aligns with regulatory requirements and risk management practices aimed at protecting human health and the environment. Regulatory agencies often mandate the implementation of containment measures, including geomembrane liners and covers, in contaminated sites and hazardous waste facilities to mitigate the risks of soil contamination and pollution.
