Why measure geotextile void size? The void size of a geotextile is measured in order to evaluate its filtration and drainage properties, which are critical in many civil engineering and geoengineering applications. Here are some of the main reasons why geotextile void sizes should be measured: Filtration efficiency: Geotextiles are often used for filtration to […]

What is the tensile strength of geomembrane properties? Performance of geomembrane Tensile strength refers to the maximum tensile force that the geomembrane can withstand under the action of tension. This is determined by tensile testing, which typically applies a tensile force perpendicular to the plane of the geomembrane to simulate the tensile stresses that may
Grab break load and elongation of geotextiles Geotextile is a material used in civil engineering and civil construction. It is usually used to reinforce soil, prevent soil erosion and improve the tensile strength of soil. Geotextile performance parameters can vary depending on the specific material and manufacturing process, so I will provide general information rather

What is geotextile? Geotextile is an engineering material, usually made of synthetic fibers such as polypropylene or polyester, which is made into cloth-like materials through processes such as needle punching, hot melting, weaving or embossing. It is widely used in civil engineering, environmental engineering and agricultural fields and has a variety of functions and uses.
What is a geomembrane? Geomembrane is a thin film made of polymer materials, mainly used in civil engineering and environmental engineering to prevent the penetration of moisture, chemicals or other harmful substances, while providing soil stability and protection of engineering structures. Such films are typically produced by extrusion, stretching, extrusion, coextrusion or other processes. The
What is the density of geotextile? The density of geotextiles usually does not refer to the actual density of the material, but to its mass per unit area, that is, mass density. The density of geotextiles is generally expressed in grams per square meter (g/m²) or grams per square centimeter (g/cm²). Geotextile density can vary
