Specialist for elastomer seals in hydraulic steel engineering

Large parts of Germany can be reached by inland waterways via the federal waterway network. The waterways have long been seen as a beacon of hope for the flow of goods across Germany, while freight transport by road is on the verge of collapse and the railways are running at their limits in many places.

Germany has a navigable waterway network of about 7300 km with a total of 170 locks along the Rhine, Neckar and Ruhr rivers. sixty percent of the locks were built from 1950, 20% of the locks even before 1900. A prerequisite for functioning inland navigation is regular maintenance or renovation of the locks, weirs, ship lifts or sheet pile walls.

Due to the many hydraulic engineering projects for the Federal Waterways and Shipping Administration WSV and the associated Waterways and Shipping Offices WSA, we are familiar with the requirements and can fulfil the tasks in accordance with the standards and hydraulic engineering regulations.
Our references range from seals for canal bridges to seals for ship lifts.

We supply note profiles, angle profiles or elaborate sealing solutions with fabric reinforcements. However, our speciality is custom-made elastomer sealing solutions that go beyond the production of simple profiles. If desired, also as moulded articles with particularly tight tolerances.

Elastomer gaskets for hydraulic steelwork

AL Gummi is known as a manufacturer of standard, special and custom profiles for solving technical tasks in hydraulic steel construction. We manufacture application-specific profiles for use as sealing elements in hydraulic engineering, weir and lock construction, as well as in harbour and canal construction.

We use high-quality elastomer materials for this purpose. For hydraulic steel construction, we use NR/SBR, EPDM and CR compounds, if required always in accordance with the hydraulic steel construction standard DIN 19704-2.

Our hydraulic engineering profiles are moulded in the factory using the “hot vulcanisation process”; for example, ready-to-install frame-profile seals, as well as angle, T and cross joints are made from corresponding profile mouldings for sluices and weirs.

We also manufacture individual large profiles with fabric inserts and special constructions if required.

Lüneburg-Scharnebeck Ship's Hoist(February 2019)

The Lüneburg Scharnebeck Ship’s Hoist, which was the world’s largest double-headed ship’s hoist at the time of its construction, was built in 1974 and is a technical spectacle well worth seeing.

The ship lift offers modern cargo ships the possibility to overcome a height of 38 metres. The Elbe side canal connects the Elbe (Artlenburg) and the Mittellandkanal (Wolfsburg). A height difference of 61 metres is overcome along the entire stretch of the Elbe side canal.

Of this, the Uelzen lock bridges 23 metres and the Scharnebeck ship lift the remaining 38 metres.

AL Gummi was commissioned with the following services in 2018:

  • Manufacture of two gap water seals made of chloroprene (CR) in the course of the revision, dimensions approx. 13m wide and approx. 6m high
  • black, 50 +/- 5° Shore A on the vertical and horizontal sections with double steel cord insertion
  • Installation and vulcanisation on site by installation team

Niederfinow boat lift(September 2014)

The 134-kilometre-long Havel-Oder Canal connects the two rivers with the Niederfinow boat lift. the difference in height, including the gradient, at Niederfinow is 36 metres. “The Havel is at the top, the Oder at the bottom. A lock was once used for this purpose at the site, then the ship lift was built in 1934.

On 16 May 2008, the Wasserstraßen-Neubauamt Berlin awarded the construction contract for the new ship lift at Niederfinow. The new ship lift is scheduled for completion in 2022.

AL Gummi was commissioned with the following services in 2014:

  • Manufacture of two transition seals U-frame made of chloroprene (CR)
  • in the course of the revision, dimensions approx. 17m wide and 8m high
  • Bead profile design with fabric insert

Note and hollow note profiles

We produce note profiles, both hollow and full note profiles. If required, if the tolerance E2 for extrusion articles is not sufficient, we can also produce the note profiles as moulded articles.

Bead profiles

We produce bead profiles, both hollow and solid. If required, if the tolerance E2 for extrusion articles is not sufficient, we can also produce the bead profiles as moulded articles.
