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.
