Due to ever greater depths, geology and difficulties with construction, faults and leaks occur in construction pits predominantly where base plates and walls meet, in joints and very frequently at the connection points between new and existing structures. DMI Injektionstechnik GmbH specialises in sealing leaks and water penetration in construction pits. To do this, we normally use extremely fast PU resins applied by means of two-component injection pumps.
Experience gives clients certainty
A number of our employees have already been deployed at the major
construction pits at Potsdamer Platz and at the Hauptbahnhof (main station) in Berlin. Swift action and experience are important to ensure water penetration does not spread and end in disaster. In the past, DMI has sealed faults with a water inflow as large as 600–800 m³/h.
A small part is often crucial to success
Delays in sealing and the danger of disaster are largely avoided by planned damage provisions. DMI has 25 fully equipped disaster containers and transporters which contain the necessary drilling machines, drill augers, packers, metal sheeting, sand sacks, connectors, pumps and grouting materials.
