SOMTUBE FTF - Draining mask

Use

Cut sections involve large and high slopes that need to be stable to avoid landslides. In case of groundwater, drainage masks construction using granular material, implies to carry and install a large amount of materials.

The use of the SOMTUBE® FTF drainage geocomposite for subsurface drainage helps to drawdown the water table and prevents water inflow on the slopes. It has a high and stable over time drainage capacity, even under heavy loads.

SOMTUBE® FTF replaces the granular drainage layer and the filtration geotextiles with a single product easy to install.

Benefits

  • Enhance soil drainage performance
  • Increased stability of the slope in the event of a draining mask application
  • Reduction of the construction time
  • Easy installation with a single product to unroll
  • Cost-effective and environmentally friendly solution as it replaces granular layers
