Safety or Ease

Is an automatic flood barrier the best option?

An option: YES, the best: NO.
Dutchdam stays away from automatically working systems including risky parts such as pumps, pipes, valves, electric drives, electricity supply and hydraulics. Parts for main functions are often out of sight.

They might fail at crucial moments. A temporary flood barrier can be out of use (and sight) for e.g. 5, 10 or 20 years. Suddenly it has to work, and during bad weather. We respect the wish of clients to have the flood barriers in place without the need of human resources.

Dutchdam is the choice for the lowest risk, all parts are on site and immediately ready for installation. A very limited action is needed giving you the maximum security. Besides this; the costs involved for automatic flood barriers is high compared to the Dutchdam alternatives. Dutchdam: to be sure of fast inspection of all vital parts at any time.

In specific situation we offer a driven system but than standard for Dutchdam: always including a manual backup.

Dutchdam uses up-to- date materials to apply cutting-edge technologies, realizing increased strength, whilst weight, volume and corrosion are decreased substantially.


New Dutchdam projects in progress:

Dublin / Ireland

for the new quay walls along the Liffey in the Dublin City Centre 11 Dutchdam flood barriers are ready for installation.

Dublin / Ireland

for the reconstruction of the coastline North of the City, and immediately along the dynamic shoreline, a Dutchdam flood barrier (salt water resistant) is commissioned.

Utrecht / The Netherlands

for the huge reconstruction of the main shopping centre “Hoog Catharijne” in Utrecht a Dutchdam system has been installed. The permanent placed parts are integrated at ground level and in the walls. The composite panels will be placed in a flat cabin close by.

To elevate all shoreline structures to a permanent maximum safety level is not realistic. Besides the technical and financial feasibility it can ruin landscapes, block the view on and access to the water. The accessibility of the shorelines represents an enormous economic value worldwide, especially in deltas, harbours and along the waterfronts.

This Cleverdam is a robust, deployable flood barrier to raise the shorelines temporarily during flood danger. The barrier is completely stored on site and will be erected only when needed. The rising sea level is a danger for the international community, as it threatens the natural and constructed shorelines. In addition to the increasing water table, the climate change brings more super storms and heavy rainfall causing huge floods. The majority of shorelines do not offer enough flood defence heights. However, this problem only occurs temporarily.

The new DUPLO-DAM

The new DUPLO-DAM, made out of steel fibre concrete and composite is Awarded during Aquatech November 2015 in The Netherlands.

The Duplo-dam is a robust, deployable flood barrier to raise the shorelines temporarily during flood danger. The barrier is completely stored on site and will be erected only when needed. The rising sea level is a danger for the international community, as it threatens the natural and constructed shorelines. In addition to the increasing water table, the climate change brings more super storms and heavy rainfall causing huge floods. The majority of shorelines do not offer enough flood defence heights. However, this problem only occurs temporarily.

The Duplo-dam is Awarded during the Aquatech in Amsterdam-NL November 2015. To elevate all shoreline structures to a permanent maximum safety level is not realistic. Besides the technical and financial feasibility it would ruin landscapes, block the view on and access to the water. The accessibility of the shorelines represents an enormous economic value worldwide, especially in deltas, harbours and along the waterfronts.

The Duplo-dam is a unique and realistic instrument to reorganize flood prone areas. The infrastructure will become better climate adaptive. The Duplo-dam, placed at ground level can include different heights, but also placed on top of a parapet as a Dam-in-Dam construction. This parapet offers already a safety level around 60 cm. / 2 feet.

“Dam-in-Dam”

The Dam-in-Dam design is very suitable to encircle objects. Dutchdam represents deployable flood defence, storage and logistics in one. All parts are stored on site, no warehousing, no logistics, provides for immediate deployment.

“Based on Unique properties and values”

When putting in place: the flood barrier has an integrated locking system over the full length, no nuts or bolts are used! (during bad weather a unique and very important feature)

  • Most reliable construction (independent third parties) with shock absorbing profiles.
  • When not in use: sea, lake and river views and accessibility will be maintained.
  • Use of light weight steel fibre concrete and composite materials, both salt water resistant.
  • Lowest life cycle costs.
  • Thanks to the extremely compact design, no rearrangements of roads, cables and pipelines because of limited use of depth in soil.
  • Saving substantial building costs and lead time.

The use of up-to-date materials enables Dutchdam to develop cutting-edge technologies, realizing increased strength, whilst weight, volume and corrosion are decreased substantially.
