Sheet membrane systems are reliable and durable thermoplastic waterproofing solutions that can fulfill the requirements of even the most demanding below-ground structures, including those exposed to highly aggressive ground conditions and stress.
A tunnel structure has to be waterproofed either with a drainage system, a water stop system or with the active control system for highest safety comprising a double-layer membrane and tested by vacuum.
Sikaplan® PVC and TPO sheet membrane systems are designed for long-term durability and ease of application to meet these needs.
Sikaplan® PVC and TPO are highly flexible sheet membrane systems and protect any concrete structure. It can be built as a standard single-layer compartment system up to the active control system to meet the highest demands.
