Filtration
Functionalities
The major function of filtration is to prevent the destabilisation of the soil by internal flows.
Action
The geotextile filter has a dual action:
- It holds back the skeleton of the soil allowing the formation of a granular auto-filter
- It lets water through
Advantages of the use of the Filtration range
- Economy of granular materials
- Reduced thickness of the filter
- Rasy and low cost implementation
- Continuity of the filtering structure in the case of deformation of the structure (possibility of seams)
