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,

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
