It combines the advantages of both geomembrane and geotextile, offering superior properties in terms of anti-seepage, tensile strength, and wear resistance.

Composite geomembrane, also known as a composite anti-seepage membrane, waterproof geotextile fabric, or geotextile waterproofing membrane, is produced through thermal bonding of non-woven geotextile or woven geotextile, HDPE geomembrane, filler, and smear agent using oven far-infrared heating and guide roller calendering technology. It is categorized into four types: one cloth and one film, two cloths and one film, one cloth and two films, and multiple cloths and multiple films.

QIVOC impermeable geotextile membrane is characterized by excellent tensile resistance, tear resistance, and puncture resistance. It exhibits good extensibility, a large deformation modulus, and resistance to acid, alkali, corrosion, aging, and low temperatures, ensuring strong impermeability. This non permeable geotextile membrane is primarily applied in projects demanding high anti-seepage and tensile strength, including landfills, pool anti-seepage projects, and road-based waterproofing projects. Its comprehensive performance makes it highly effective in complex environments.

Impermeable Geotextile Membrane Installation Procedures

Using and installing the impermeable geotextile membrane is straightforward and convenient. Below is a standard construction process.

  1. Ensure the base surface is thoroughly cleaned according to design specifications, crucial for achieving an effective anti-seepage effect. Remove sharp stones, tree roots, and debris completely. The base surface should be tamped tightly with a tamping hammer or plate, ensuring it is both dense and smooth, with no local unevenness permitted.
  2. Impermeable geotextile laying is divided into two segments: bottom canal placement and slope installation. For horizontal placement, roll along the channel axis. For slope installation, roll along the slope axis direction after passing slope acceptance, ensuring a T-shaped connection with the bottom canal waterproofing geotextile.
  3. Press the film flat and tightly between film and base surface, avoiding excessive tension. Generally, it should be slightly loose, without leaving bubbles underneath. Due to the thin and light nature of the non permeable geotextile membrane, it is susceptible to wind before the protective layer is laid. Therefore, cover the area with soil while laying the film, avoiding overly large areas at a time.
  4. Upon identifying a puncture or tear in the impermeable geotextile fabric, promptly repair it using geotextile waterproof membrane adhesive, ensuring coverage three times the damaged area.
  5. Conduct welding operations after completing the laying process.
    • Overlap: Ensure the overlap width is greater than 15cm.
    • Heat welding: Suitable for slightly thicker geotextile impermeable membrane base materials, with the weld overlap width not less than 5cm. (Note: Avoid gluing, as it may open when soaked in water for an extended period, compromising the anti-seepage effectiveness.)

Precautions for Installation of Non Permeable Geotextile Membrane

While the construction of composite geomembrane is relatively simple, attention to the following considerations is crucial during installation. Here are specific precautions for waterproof geotextile fabric installation:

  1. Avoid direct impact on the geotextile waterproofing membrane by stones and heavy objects during construction. It is advisable to lay the membrane and cover it with a protective layer throughout the construction process.
  2. Anchor the connection between the waterproofing geotextile sheet and surrounding structures using expansion bolts and steel plate battens. Coat the connection parts with a 2mm thickness of emulsified asphalt for bonding, preventing leakage.
  3. Ensure the soil is compact to prevent uneven subsidence and cracks. Remove turf and tree roots within the anti-seepage range. Lay sand or clay with a small particle size on the contact surface with the membrane as a protective layer.
  4. When laying, avoid pulling the impermeable geotextile membrane too tightly. It’s better to have the parts buried in the soil at both ends in a corrugated shape, especially when anchored with rigid materials, leaving room for expansion and contraction.
  5. Implement careful peripheral junction treatment to tightly connect the impermeable geotextile with the surrounding soil. Dig cutoff trenches at the perimeter junction, burying the impervious geotextile in the trenches to block seepage entrances and prevent lateral leakage paths, thus avoiding seepage entering the bottom surface of the anti seepage geotextile and forming blisters.
  6. Keep joints as short as possible in corners and deformed areas. Unless there are special requirements, avoid welds within 1.5 meters of the top slope or stress concentration area on slopes with a slope greater than 1:6.
  7. After laying the waterproofing geotextile, minimize walking and moving tools on the membrane surface. Avoid placing any objects that may harm the anti-seepage membrane or carrying items on the membrane to prevent accidental damage.
  8. For ease of construction and ensuring splicing quality, make the impermeable geotextile fabric as wide as possible to reduce on-site splicing. Cut the composite geomembrane into units according to width and on-site length requirements before construction. Splice it into blocks that meet the required size, roll it on steel pipes, and manually transport it to the working surface for laying.
  9. Conduct laying in dry and warm weather. To facilitate splicing and prevent stress concentration, lay the waterproofing geo fabric in a wave-shaped relaxation method with a margin of about 1.5%. After spreading, level it and pull it apart promptly.
