The double layer of waterproofing membranes, knowing as a double ply will be delivered with compartmentalized sections, which is sealed forming a pocket with approx. 100m2. The second membrane which will cover the system is embossed to ensure the vacuum capability of this once the system is installed.

Each compartment has between 3 to 5 points of injection, which is testable by using a pump to extract de air from the pocket during construction phase. Any defects can be easily found and repaired before the installation of the protection layer and final secondary lining. The entire system is testable and injection pipes can be left in place, to enable further tests as work progresses.

SYSTEMS DESCRIPTIONS:

  1. Supporting Element (Primary lining)
  2. PROTAN Geo 1000g (Drainage/protection layer)
  3. PROTAN InfraPlan P20 (Waterproofing Membrane)
  4. Protan InfraPlan PT20/ST (Translucid waterproofing membrane)
  5. PROTAN Waterbar PVC-P (Injection System)
  6. Welding
  7. PROTAN Inject (Injection hoses)
  8. PROTAN Protect 20 (Protection layer)
  9. Shotcrete (Secondary lining)
  10. PROTAN Disc

 

 

Protan recommends a double barrier system for hydrostatic pressure. Use InfraPlan P20 or P30 PVC-P membrane as the first layer and PROTAN InfraPlan PT20 / ST (PVC-P) as the second layer to achieve vacuum system. Depending on ground conditions choose a PROTAN Geo (drainage/protection layer) from 700g to 1200g. Finish with PROTAN Protect 20 before applying the secondary lining.
