Since many years Prematek services are required to sealing leakages in underground infrastructures as tunnel, shaft, metro lines and deep parking areas by worldwide primary client.

Using own know-how in ground polyurethane resin injection, we are solving problems as unexpected and massive water ingress into excavations or sealing concrete cracks and joints to waterproof existent underground structure. We can seal leakages from 0,01 to 500 litre by second.

Polyurethane resins and machineries are fully managed by our teams, but also only engineering consultancy is supplied to train the team of our clients.
