The primary mechanism of geomembranes is to interrupt the leakage pathways of soil dams through the impermeability of plastic film, with their high tensile strength and elongation to withstand water pressure and accommodate dam deformation; while the lack of
Spunbond fabric is a type of high molecular short fiber chemical material, formed through needle punching or thermal bonding, boasting high tensile strength and elongation. When combined with plastic film, it not only increases
Enhanced the tensile strength and puncture resistance of plastic film, and due to the rough surface of the non-woven fabric, increased the friction coefficient of the contact surface, which is favorable for the stability of composite geomembranes and protective layers.

Geotextiles have been widely used around the world for only 30-40 years, and in China for less than a decade. There is a lack of application experiments on aging phenomena during use, and various aging test results are
Lacking a correlation with actual applications, research on anti-aging properties is being conducted proactively as TenTen Film is being widely promoted for large-scale use, identifying the appropriate anti-aging property tests.
By utilizing laboratory data to evaluate and predict actual aging performance, the development and production of raw materials for geomembranes, and the rational use of geomembranes, reliable bases are provided for engineering design, which is crucial for ensuring the safety and quality of various applied projects.
All geotextile membranes and seams must be inspected. Defective geotextile membranes and seams need to be clearly marked on the membrane and repaired. The geotextile membranes should be laid out and thermally connected.
To repair worn ten-inch film, the ten-inch film patches must be at least 200mm longer than the edge of the defect in all directions. Thermal bonding must be strictly controlled to ensure the integrity of the ten-inch film patches and the ten-inch film.
The film bonds tightly and does not damage the ten-diameter film. Before the day's laying is completed, a visual inspection is conducted on the surface of all the ten-diameter films laid that day to ensure that all damaged areas have been marked.
Identify and repair immediately any foreign objects that could potentially damage the laying surface, such as tiny needles, small nails, etc. At the bottom of the landfill, if the geotextile membrane has tears exceeding...
If the material width is 10% damaged, the damaged portion must be cut out, and then the two pieces of film must be connected: if the crack exceeds 10% of the film width on the slope, the affected roll of film must be removed.
Please replace with a new roll. Construction personnel should ensure that their work shoes and equipment do not damage the geotextile. They must not perform any activities on the laid geotextile that could cause damage, such as smoking or using sharp tools to puncture the geotextile.
