Van Oord to Use New Dike Improvement Method

Van Oord and GMB are about to use innovative dike pins for the first time on a dike improvement project between Hagestein and Opheusden, the Netherlands.

The great advantage of this dike reinforcement technique is that it can be used in places where working space is limited.

The client, Rivierenland Water Board, is embracing this new method for use in the Hagestein-Opheusden Dike Improvement Project.

Dike pins are steel anchor rods encased in cement. They are inserted into the underlying layer of sand and prevent the possibility of the dike collapsing during floods. Installing the pins is an effective way of making dikes safer.

When working space is limited, e.g. by houses and vegetation, the problem can be solved by using this innovation. The dike pins are installed completely inside the existing dike profile, so that it is not necessary to interfere with the crown or the foot of the dike.

During the work, the surrounding area suffers much less disruption than with the traditional installation of sheet piling or soil replenishment, while still being kept safe from flooding.

This innovative method of dike reinforcement is the result of close cooperation between Van Oord, GMB, BAM Speciale Technieken and RoyalHaskoningDHV. The innovation has been further improved on the back of a number of tests and pilot projects.

According to Johan Bakker, Director of Innovation at Rivierenland Water Board: “Innovation succeeds more often than not. That is also the case here. To keep the Netherlands safe and to keep safety affordable, we – in a joint effort – have to pull out all the stops.”

The HOP dike improvement scheme involves reinforcing about 18 km of dike spread over two dike rings, ten work areas and five municipalities. The first and last work areas are 40 km apart on the southern bank of the Lower Rhine and Lek.

3rd International Congress Hydraulic Engineering Structures and Dredging

Russia’s leading maritime industry Media Group PortNews ( holds a traditional annual Congress “Hydraulic Engineering Structures and Dredging” in Moscow. 

The two-day Congress includes the 7th International Forum of Dredging Companies and the 3rd Technical Conference “Modern Solutions for Hydraulic Engineering”.

Infrastructure development is among the real sources of Russia’s economy growth. Construction of port facilities and new hydraulic engineering structures on the country’s inland waterways constitute an essential part of all infrastructure projects. It is important to take into account the best international practices to implement these projects effectively.

The program of the Congress will be devoted to the latest technologies for dredging and hydraulic engineering works. Speakers and delegates will refer to real projects to discuss specifics features of dredging works, as well as dedicated fleet and equipment involved.
