Protan delivers waterproofing systems for both Single and Double Barrier applications.
Single Barrier System is for hydrostatic water pressure conditions including compartments and injection possibilities. Double Barrier System is also designed to withstand hydrostatic water pressure and combines a test and injection system.
The system consists of two tunnel membrane layers:
To obtain vacuum between the two layers, the second layer membrane is delivered with an embossed surface in contact with the first layer.
Examples of Application:
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.
