InnoTek SEALS have been especially developed to avoid:

- Flow of the backfilling grout towards the head (SEALtek TBM – C)
- Water and mud penetration in the TBM bearings (SEALtek TBM – T)

InnoTek, thanks to its experience in this field, was able to develop two products capable of preventing intrusion of water, mud and dirt inside the TBM shield and bearing.
Consumption of tail seal grease as the TBM advances is also cut to the minimum thanks to the products' rheological properties and its perfect adhesion to any type of substrate.
