7. Conclusion

The use of geosynthetics for reinforcement is now commonplace. Academic research and industrial product development have resulted in a wide range of solutions to geotechnical stability problems. The harmonization of testing standards has resulted in unified nominal characteristics for geosynthetics. The harmonization of dimensioning approaches will enable the technique to flourish once again.

Innovation in the field of geosynthetics is needed to meet the challenges of more complex infrastructure construction. The development of new geosynthetic reinforcement layers requires qualification on the major points that enable the design of reinforced structures:

• long-term mechanical and chemical resistance ;

• resistance to damage and ageing (service life of the structure) ;
