Geotextile is a filter material used in civil engineering and environmental engineering. It has a sieving and filtering effect and can be used to control the drainage of soil particles and the migration of soil particles. Filtration principle of geotextile Screening: Geotextiles, through their fabric structure and pore space, can screen larger particles of soil […]

Geotextile is an engineering material widely used in civil engineering and environmental engineering, with multiple functions and functions. 5 main functions of geotextiles Separation: Geotextiles can be used to separate layers of different substances to prevent their mutual mixing and penetration. For example, in road engineering, geotextiles can be placed between the subgrade and the

The elongation of a geotextile refers to the extent to which a geotextile can stretch under tensile loading, usually expressed as a percentage. Elongation is an important index to evaluate the flexibility and ductility of geotextiles. Elongation testing of geotextiles is usually performed in a standard tensile test. The following are the general elongation test
The geomembrane fusion covering method is a commonly used method for making geomembranes. It is suitable for on-site construction, and the purpose of soil seepage prevention and soil protection is achieved by coating the melted geomembrane material on the soil surface. The production process of geomembrane fusion covering method Material preparation: Select suitable geomembrane materials,

Geomembrane, also known as mulch or geosynthetics, is a material used for soil seepage prevention, anti-leakage and soil protection. What are the geomembrane manufacturing processes Material preparation: Select the appropriate geomembrane material, usually high-density polyethylene (HDPE), linear low-density polyethylene (LLDPE) or polypropylene (PP). For large projects, the material may need to be pre-fabricated to size

The tensile strength test and tear strength test of geomembrane are one of the important indicators to evaluate the mechanical properties of geomembrane materials. A geomembrane is a thin film material used to prevent the penetration of water, gas or chemicals. Common geomembranes include HDPE (high-density polyethylene), LDPE (low-density polyethylene), PVC (polyvinyl chloride), etc. Tensile

The installation difference between HDPE geomembrane and PVC geomembrane Material flexibility: PVC geomembranes are more flexible and malleable than HDPE geomembranes. This makes the PVC geomembrane easier to bend and fit to irregular surfaces and shapes during installation. HDPE geomembranes are relatively rigid and require more handling and welding operations to fit a particular structure
