Design & Engineering

Under the watchful eye of the Governor of the State Massachusetts Charlie Baker and the Dutch Prime Minister Mark Rutte a Letter Of Intent has been signed between the designer of the Climate-dam Corné Rijlaarsdam and André de Graaf for Trelleborg.

Launch Climate-dam

The new Climate-dam technology launches on July 16th ‘19 in BOSTON MA USA

This catching development will be disclosed during the Dutch economic mission to the US being led by the Dutch Prime Minister Mark Rutte.


Dutchdam adds more permanent installed flood barriers, stormwater pickups and heat stress remedies to its programme.

The climate change causes a spread of locations asking for human intervention in case of sudden stormwater and/or flooding. During upcoming bad weather big area need many hands in short time, this is a great risk. That’s why Dutchdam brings more permanently placeable systems to get cities better and durable climate proof. A Climate-dam improves city life and supports public/private values in dense cities. Heat stress, flood and stormwater mitigation in one.

Designed by Corné Rijlaarsdam ©2019, all rights reserved, patent applied for. To work with the Climate-dam designs a license, based in the Netherlands, is needed. More information is under construction and will be published on dutchdam.com / climate-dam.com For questions please ask: info@dutchdam.nl

Climate change elevates the Dutchdam

Dutchdam installed many deployable flood barriers with heights up till 5ft./1.5m. This will change, flood levels increase, we need higher flood barriers, possibly even as high as 10ft./3m.

Read more, see two fact sheets..

The materials for those heights are no longer easily stored in boxes below ground level. That’s why Dutchdam introduces the new ‘Double-dam’. But we will stay insitu and store all materials above ground level. The flood barrier is instantly available.

Such a design is -seen from the technical point of view- as a firm step forward. As well as the effects for the client and the water safety.

The first part of the barrier (stored at half of the defence height) is shaped as a box and holds a second part. That second part can be lifted to reach the full height of the barrier. The first part, the box itself, can turn like a door to become a flood barrier for the upcoming flood.
In case the water level seems to overtop this first part, the second part is available to increase the height.

Putting the barrier in place requires very limited man power and lead time.
This new ‘Double-dam’ is strong, stable during storms from each direction (also before flood water arrives) and fast. A flood barrier always on site protecting the community, the landscape, view and access when not in use.

This ‘Double-dam’ can reopen the site for local traffic immediately after the flood is gone, and includes a high standard of operational security.
