Design & Engineering


Dutchdam forms a consortium with specialized
partners to implement the Climate-dam technology.

For both, stormwater ànd heat stress

This consortium helps cities, (which are suffering
under heavy stormwater flooding and/or heat stress)
how the Climate-dam technology can be applied
in cooperation with local parties.

Water in – Water out

The Climate-dam has (where required) a reversible
flow direction for the immediate pick up of stormwater
from the streets or for water supply in summer.

We will welcome your interest in this typical Dutch
knowledge field based on 800 years of experience.

Our Climate -our future-

we all share, we all care.

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.


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

This catching development is 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.

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.
