Geosynthetic permeability testers are used to determine the impermeability and hydrostatic pressure resistance of various geosynthetic materials in order to assess their reliability in seepage control projects.

Geosynthetics Impermeability Tester

Model:TGHCK-1

Product Introduction:

This instrument is developed and designed strictly according to national standards such as SL/T 235-1999, JTG E50-2006, GB/T 19979.1-2005 (Geosynthetic Materials Impermeability and Hydrostatic Pressure Resistance) and GB/T 19979.2-2006 (Geosynthetic Materials Impermeability and Permeability Coefficient). It is suitable for testing the impermeability (water resistance) and permeability coefficient of various geosynthetic materials. The equipment is stable in performance and easy to operate, meeting the needs of laboratory and engineering testing.

Furthermore, this instrument fully complies with international standards such as ISO 11058:2019, ASTM D4491/D4491M-22, ASTM D5385/D5385M-25, and ASTM D5886, making it suitable for the international market and particularly suitable for export.
