Embankment construction

The following are examples of projects in Hamburg which could be successfully realised by the use of iron-silicate stone

Expansion of Airbus works

For this project in Hamburg-Finkenwerder, iron-silicate stone was used in the Mühlenberger Loch and Rüsch peninsula sectors with the new marina for bank protection, slopes and securing the harbour bottom along the new about 7 km long flood control system.

Client: ReGe Hamburg
Contractor: Möbius Bau, HH / Colcrete von Essen, Rastede
Scope: 300,000 t

Köhlbrand east side

The Köhlbrand outer curve was reinforced along its entire length with an erosion-stable layer of iron-silicate products due to the increased hydraulic exposure resulting from tide action and shipping traffic.

Client: HPA
Contractor: Heinrich Hirdes, HH / Colcrete von Essen, Rastede
Scope: 80,000 t

Compensation measures Hahnöfersand

Freshwater mudflats and shallow water areas have been created by relocating the dyke and sand removal (sand supply for the Mühlenberger Loch). Iron-silicate stone was used for the work on the embankment slope.

Examples of projects for bank protection in internal waterway and coastal sectors

Kiel Canal

Iron-silicate hydraulic construction stone has been successfully used in the Kiel Canal for the canal extension since 1970. The bank protection has to withstand very high stress on account of the shipping traffic. Our product’s high dry apparent density offers particular advantages for this application.

Client: WSA Brunsbüttel / Kiel-Holtenau / NBA Rendsburg

Groynes in the Mittelelbe River

Iron-silicate stone has been used for groyne maintenance at the river Elbe (Oberelbe and Mittelelbe) for decades. The high density of iron-silicate stone ensures very good stability even with high current action and ice exposure.

Client: WSA Lauenburg / WSA Magdeburg

Minsener Oog

On Minsener Oog, the river constructions which should prevent the drifting of the sand masses into the waterways of the Jade are preferably built with iron-silicate stone. As a result the constructions withstand the extreme force of nature.
