Filtration

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)
