Underwater concrete

Spezialtiefbau: Unterwasserbeton einbringen

According to your requirements we produce various kinds of underwater concrete floors (UWBS) as well as underwater concrete plugs. Examples: tunneling, underpasses, bridge and escape shafts.

  • 3D lot plans: we analyse building excavation floors by constructing a 3D lot plan or surface sonar.

  • General and detailed planning with Damen hydraulic pump: straightening of building excavation floor by means of Damen-high performance-hydraulic pump (accuracy ±10 cm, at a solids content of max. 30% a capacity up to 600m³/h and jetwater crown with 150m³/h at 7 bar can be reached).

  • Equipment of anchor plates with altitude control

  • Underwater cleaning: cleaning of sheet pile walls, auger piles, slurry walls etc. by using high pressure jet.

  • Sludge suction: suction of sediments before inserting underwater concrete, suction of emerging sludge rolls during concreting.

  • Concrete placing: placing of underwater concrete via pumping method; height control during concrete placing by rotating laser.

  • Compression work: installation of predetermined breaking point and compression hoses as securing instruments; drilling of injection holes; setting pressure-grouted anchor, sealing of building excavation.
