Geomembrane Installation Procedures
The geomembrane liner installation is simple and convenient. The following is the standard construction process.
- Before commencing installation, thoroughly clean the construction area, removing any sharp objects and debris to ensure a smooth foundation.
- Measure the length and width of the geo membrane accurately for precise cutting in accordance with project requirements. Ensure complete coverage of the targeted project area.
- Lay the cut impermeable geomembrane in the designated area, taking care to avoid wrinkles.
- In cases where the construction area exceeds the width of the impervious geomembrane, seam welding is necessary. Utilizing a dedicated welding machine for seam processing ensures superior impermeability.
- Secure the edges and joints of the waterproofing geomembrane using fixed strips, nails, etc. Ensure the geomembrane liner remains stationary during use.
Precautions for Geomembrane Liner Installation
While the construction of geomembrane is relatively simple, attention to the following considerations is crucial during installation. Here are specific precautions for geomembrane liner installation:
- Avoid dragging or pulling the geo membrane during transportation to prevent damage from sharp objects.
- Extend the geomembrane liner from the bottom to a higher position without excessive tension, maintaining a 1.50% margin to accommodate local sinking and stretching.
- Ensure that longitudinal joints of adjacent panels are not on a horizontal line, but staggered by more than 1m.
- Keep longitudinal joints more than 1.50m away from dam and bent foot, locating them on a flat surface.
- Start installation from the side slope and then proceed to the bottom of the field.
- When laying on a slope, align the film expansion direction parallel to the maximum slope line.
- Accurately measure relevant dimensions before cutting the geomembrane sheet.
- Minimize welds while laying the impermeable geomembrane.
- Ensure the overlap width of seams between membranes is generally not less than 10cm. Typically, arrange welding seams parallel to the maximum slope, following the slope direction.
- In corners and deformed areas, minimize the length of joints. Except for 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.
- Stretch the waterproofing geomembrane as tightly as possible during laying.
- After laying the impervious geomembrane, minimize walking and tool movement on the surface to prevent damage to the membrane liners.

Polyethylene Geomembrane Production Process
1. Selection of raw materials
The main raw materials of geomembrane include high-density polyethylene (HDPE) resin, low-density polyethylene (LLDPE) resin, antioxidants, antioxidants, and pigment.
2. Production process steps
The production process of geomembrane mainly includes the following steps.
2.1 Mixing according to the proportion
According to the specifications and performance requirements of the geomembrane, HDPE/LLDPE resin, antioxidants, antioxidants, and pigment are put into the mixing machine for mixing according to a certain ratio.
2.2 Melt extrusion
Put the mixed raw materials into the extruder, through heating and melting, the solid raw materials will be transformed into molten melt.
2.3 Extrusion molding
Extrude the molten raw material from the extruder and mold it through the die plate.
2.4 Cooling
The extruded geomembrane is cooled through a cooling device to harden it quickly and keep its shape and properties stable.
2.5 Stretching and Shaping
The cooled and hardened geomembrane is stretched and shaped to improve its strength and stability.
2.6 Cutting and trimming
Cut and trim the geomembrane after stretching and shaping according to the specifications to get the finished product that meets the customer’s requirements.
Geomembrane Sheet Quality Control
The quality inspection process of the geomembrane is an important link to ensure the quality of the product, mainly including the following aspects.
3.1 Thickness and width measurement
Measure the thickness and width of the geomembrane with professional measuring instruments to ensure that it meets the specifications.
3.2 Strength test
Use the tensile testing machine to carry out strength tests on the geomembrane, including tensile strength, tear strength zigzag strength, and other indicators.
3.3 Density test
Use a density tester to test the density of the geomembrane to ensure compliance with the requirements.
3.4 Aging test
Expose part of the samples to conditions such as high temperature and ultraviolet rays to carry out aging tests to assess the weathering performance of the geomembrane.
3.5 Other tests
Other tests, such as impermeability tests, chemical corrosion performance tests, etc., can be carried out as required.
Packing, Transportation of Geo Membrane
Geomembranes that have passed the quality inspection will be packaged and stored to ensure the integrity and stable quality of the product.
Packaging is generally in woven bags or according to your customized requirements, while the product specifications, batch number and production date, and other information are marked on the packaging.
The default transportation option is usually sea freight, or land freight. It can also be shipped according to your requirements.
