Geomembrane is a geotechnical anti-seepage material composed of plastic film as the anti-seepage substrate and non-woven fabric. Geotextile, also known as geotextile, is a permeable geosynthetic material made from synthetic fibers through needle punching or weaving. Therefore, there are still many differences between the two. The manufacturer of geomembrane will provide a detailed introduction below. Geomembrane construction involves applying geotextile on one or both sides of the membrane to form a composite geomembrane, which can take the form of one cloth, one membrane, two cloth, one membrane, etc. The geotextile is used as the maintenance layer of the geomembrane, so that the maintenance impervious layer will not be damaged. In order to reduce the ultraviolet radiation and increase the anti-aging function, the embedding method shall be used as far as possible.
During construction, first use sand or clay with a smaller material diameter to level the foundation surface, and then lay the geomembrane. The geomembrane should not be too tight, and the parts buried in the soil at both ends should be corrugated. Then, use fine sand or clay to lay a layer of about 10cm transition layer on the geomembrane, and lay 20-30cm block stones (or precast concrete blocks) as anti erosion maintenance layers. During construction, try to prevent stones from directly hitting the geomembrane, Try to construct the maintenance layer while laying the membrane as much as possible. The connection between the composite geomembrane and surrounding structures should be anchored with expansion bolts and steel plates. The connection area should be coated with emulsified asphalt to prevent leakage.
Geomembrane and geotextile are commonly used geotextiles in civil engineering construction. Due to their common use as geotextiles and waterproofing materials, and their many similarities, most people believe that they are the same building material, but in fact, they are different materials. Geomembrane is made of high-density polyethylene, mainly used for anti-seepage, while geotextile is made of non-woven fabric, mainly used for strengthening the foundation. Its anti-seepage function mainly depends on the anti-seepage function of plastic film. When we use it, we usually combine them together, dividing them into one cloth and one film, and two cloth and one film, which have stronger reinforcement and anti-seepage functions.
Geotextile is a permeable geosynthetic material made from synthetic fibers that are needle punched or woven. It is widely used in highways, railways, water conservancy, large-scale construction, power plant ash dam construction, non-ferrous metal tailings treatment, environmental protection engineering, soil and water conservation, and other aspects.

Geomembrane is a relatively impermeable geosynthetic material. According to different raw materials, it can be divided into two categories: polymer and asphalt. To meet different strength and deformation needs, there is a difference between unreinforced and reinforced. Polymer films are produced in factories, while asphalt films are mostly produced on-site.
