Principle of Geomembrane Geotextile Composites

Geomembrane geotextile composites are divided into woven and non-woven, both of which have good filtration, drainage, isolation, reinforcement, impermeability, and protection functions, and are characterized by lightweight, high tensile strength, good permeability, high-temperature resistance, frost resistance, aging resistance, and corrosion resistance. It is a good new material for a roadbed construction project. Its outstanding advantages are the combination of anti-seepage and drainage in one, high tear strength, simple and convenient construction, large friction coefficient, and good aging resistance in one, which can well solve the roadbed drainage problem. So what is the principle of this composite geomembrane? Here we will introduce its principle in detail.

The following is the list of contents:

• Principle for isolation

• The principle used for filtration

• Principle for roadbed reinforcement

Principle for isolation

Using geomembrane geotextile composites can isolate construction materials with different physical properties (particle size, distribution, consistency, density, etc.), such as soil and sand, sand and gravel, soil and concrete, so that there is no loss and no mixing between the two materials, maintaining the overall structure and function of the materials and strengthening the load-bearing capacity of the structure. Our composite geomembrane is made by thermally bonding a non-woven geotextile to a geomembrane sheet. The composite material has the functions and advantages of geotextile and geomembrane. The warp-knitted composite reinforced waterproof composite membrane has superior water resistance, durability, and protection.

The principle used for filtration

The non-woven geomembrane geotextile composites material has good filtration, when water flows from the fine material soil layer into the coarse material soil layer, using its good permeability and water permeability to make water flow through, effectively retaining soil particles, fine sand, small stones, etc., to maintain the stability of soil and water projects; it can also play a reinforcing role, using the composite geomembrane to enhance the tensile strength and deformation resistance of the soil, increasing the stability of the building structure and improving the soil It can also effectively diffuse, transfer or decompose the concentrated stress to prevent the soil from being damaged by external forces.

Principle for roadbed reinforcement

In roadbed reinforcement, composite geomembrane is widely used in road maintenance. Composite materials are mainly used in highway maintenance to protect the wetting and maintenance of new pavement and prolong the service life of the highway. It can also be used for the reinforcement of rigid and flexible pavements such as asphalt pavement, cement concrete pavement, and roadbeds. Geomembrane geotextile composites can also be used as a back filter layer in the design of seepage trenches to lower the water table and prevent frost swelling and overturning of highway roadbeds. We produce composites with enhanced puncture resistance, tear resistance, and friction related to sliding, and also have their tensile strength, while also providing waterproofing and reinforcement.
