It is used to test all kinds of geotechnical impermeable materials, such as geomembrane, composite geomembrane, geotechnical waterproof membrane material, and other waterproof and impermeable materials to determine the hydrostatic pressure resistance.

When the pressure head on both sides of the sample reaches a certain value, the sample ruptures; increase the hydraulic pressure difference on both sides step by step and keep it for a certain period of time. When the seepage flow increases rapidly, indicating that the sample is damaged, the hydrostatic pressure value is obtained. The machine can contain two functions, namely the measurement of hydrostatic pressure resistance and the measurement of permeability coefficient.
