The unit has a laboratory dedicated to geosynthetics. It is equipped with technical means for the study and characterisation of geotextiles and geomembranes.
Contact: Roland Gallo
Research and trials are conducted with equipment which was mainly developed by the IRSTEA Institute. This work focuses on both the mechanical and hydraulic properties of geosynthetics.
The laboratory, approved by COFRAC , has acquired considerable experience in the hydraulic properties of geotextiles: permeability, opening size and flow capacity in their plane (Photo 1).
For geomembranes, the laboratory has also developed a test bench (photo 2) to measure their permeability.
Other equipment is used to characterise the behaviour of geomembranes subjected to punching by aggregates or biaxial properties. More conventionally, the laboratory can also characterise their mechanical properties in uniaxial tension (Fig. 3).
