Objectives

This course aims to provide information about polymers materials currently called geossynthetics.
Therefore, the course goal is to provide knowledge on:
- Constituent polymers and geossinthetics structures;
- The functions that these materials can operate in Civil Engineering works and the properties related to the performance of that functions;
- These materials tests;
- Sizing methods for each geossynthetics function;
- Constructive procedures
