The system consists of two tunnel membrane layers:

First layer being the main membrane, maximum 4mm thick.
Second layer, a 2mm membrane is placed on top of the first layer.
To obtain vacuum between the two layers, the second layer membrane is delivered with an embossed surface in contact with the first layer.

  4. Protan Inject (Injection hose)
  5. In-Situ concrete
  6. Protan InfraPlan Tunnel Membrane
  7. Protan Geo (Geotextile)
  8. Shotcrete

Protan recommends to use InfraPlan P32+ for the Single Barrier System for hydrostatic pressure.

For Double Barrier Systems, Protan recommends to use InfraPlan P32+ on the first layer and an embossed InfraPlan P20 as a second layer.
