Developed for many applications (infrastructure, roads, civil engineering, environmental protection, waste management, drainage and irrigation, building shells), geosynthetics are alternative materials to construction materials and include a multitude of specific products.

Evaluation of hydrostatic perforation of geomembrane on a mixture of soils.

Preparation for the evaluation of geofoil prototype at low temperature.


Geomembranes are mainly used in the construction and civil engineering sectors to protect structures, prevent water infiltration or the flow of pollutants into the ground. Thin, flexible, waterproof or semi-waterproof, they are also required to be durable in order to comply with current guarantees and standards.

Geotextiles are mainly used for soil separation and filtration. We are working to improve methods of analysis and to predict the behavior of these materials under extreme stress, particularly to anticipate punching or clogging in real-life situations.

Drainage geocomposites are used to better channel discharges from water, either surface or underground, leachates, and require special expertise. CTT Group is involved in improving the use of these products for industrial applications.

Beyond these few examples of product development, we are actively involved in the evaluation of material durability, including life cycle projections and estimates.
