What are the main test items of geosynthetics products？

    As some enterprises use recycled raw materials, their tensile indicators such as breaking strength and elongation do not meet the standard requirements;

   Due to the small scale of the enterprise, the weak technical force, and the excessive quality deviation rate per unit area, it causes certain difficulties for the design and construction units;

  The composite equipment and processes of individual companies do not meet the standards, and the hydrostatic pressure indicators of some waterproof composite materials do not meet the requirements of national standards. If the product is not discovered in time and flows into important construction sites such as water conservancy, it will bring unforeseen serious consequences to the quality of the entire project. At present, the main test items of geosynthetics include width, width deviation rate, mass deviation rate per unit area, thickness, air permeability limit deviation, breaking strength (wide strip), breaking elongation, CBR burst strength, equivalent pore diameter, vertical Permeability coefficient, tear strength, thermal stability and other key technical indicators that affect the quality of the project.
