Geotextile, also known as geotextile, is a water-permeable geosynthetic material made of synthetic fibers by needling or weaving, which is divided into woven geotextile non-woven geotextile and composite geotextile. Geotextile testing and inspection is very necessary for both manufacturers and relevant parties that will actually use geotextiles in engineering. The quality of geotextiles can be directly judged by whether certain detection indicators are up to standard, but the judgment results of a single indicator sometimes cannot meet the actual needs, so more indicators need to be tested, and comprehensive judgment is made by combining the detection results of a number of indicators, which will be more direct help for the later use of geotextiles or the improvement of production process.

Test Range
Non-woven geotextiles, woven geotextiles, composite geotextiles, needled geosynthetic materials, woven geotextiles,etc

Test item
Geotextile quality testing mainly focuses on four categories of properties: physical properties, mechanical properties, hydraulic properties and durability properties.
It mainly includes: Thickness, UV resistance, friction characteristics, vertical and horizontal fracture strength, elongation at constant load, elongation at constant load, bursting strength, piercing strength, mass deviation rate per unit area, width deviation rate, water permeability, equivalent pore diameter, vertical permeability coefficient, tearing strength, acid and alkali resistance, oxidation resistance, tensile strength at seam, holding tensile strength, creep performance, falling cone penetration, etc
