Aggeres Flood Solutions and the Aizawa Concrete Corporation have announced a strategic alliance

Friday, December 6th, 2019

SCHOTEN / TOKIO – (03/12/2019) After a successful mission with the ‘EU Gateway to Japan’ in March, and a preliminary return visit by Mr Seiji Nakamura in June, we were honoured by the visit of the Japanese Aizawa Concrete Corporation. Together with its CEO, Mr Yoshihiro Aizawa, we presented our company and finalised the details for a strategic alliance for the Asian market.

The Aizawa Concrete Corporation, with offices in Tokyo, Sapporo, Singapore, Yangon, Hong Kong, Shanghai, Delhi, Vladivostok and Ulaanbaatar, is our preferred partner for the introduction of the Aggeres flood defence products and services into Japan and Asia.

The added value is in both directions, as Aizawa’s expertise in prefabricated concrete will help us improve the efficiency of large scale projects.

< The recent floods in Japan and ongoing problems in the South East Asian region clearly show the need for urgent innovative solutions. The experience of Aggeres as a supplier to the Dutch and Belgian Government in this domain will accelerate the implementation of these systems. > Mr Anthony Femont, Director, Aggeres

The first projects in Japan are already being studied, and will be realised in 2020. We look forward to the return trip to Japan and the future collaboration.

<AIZAWA is very pleased to have started a strategic partnership with Aggeres in Japan. We are confident that the joint venture with Aggeres in Japan will lead to further business expansion in Asia. We believe that Aggeres’ technology and products protect people’s lives and assets against Asian climate change, which is becoming more serious as a result of global warming.>Mr Yoshihiro Aizawa, CEO, Aizawa Concrete Corporation.>

About Aizawa Concrete Corporation: Established in 1963, Aizawa Concrete Corporation is a quality manufacturer in the field of cements, ready-mixed concretes, pre-stressed concretes, concrete piles, and other housing materials.

Self-Closing Flood Door for private residence in Kruiningen, Netherlands

Monday, March 18th, 2019

This week we commissioned a Self-Closing Flood Door for a private residence in Kruiningen (Netherlands). The garage had already been flooded twice during heavy rainstorms. Rain- and surface-water which could not be evacuated by the overloaded public sewer system flowed into the lower lying garage, causing considerable damage.

Thanks to the SCFD this will be a thing of the past. In the event the SCFD’s drain is no longer able to evacuate rain- or surface-water the surplus water will flow into the underground basin which holds the floating flood-wall. The pressure of the upcoming water will push the barrier up and close off the entry to the garage.

The SCFD works autonomous, not requiring any external energy source nor human intervention. Barrier length 5 m, protective height 0.3 m.




8m long & 2m high Self-Closing Flood Barrier from AGGERES installed in underwater-film-studio

Monday, October 29th, 2018

29-10-2018 — In October AGGERES completed the installation of the 8m long and 2m high flood barrier in Europe’s largest underwater film-studio in Vilvoorde, near Brussels.  Eight 2.6m high elements were assembled on site and lifted into the underground holding bassin. The complete barrier weighs 1 Ton. The installation was done in 2 days.

When the studio is flooded the barrier will be activated by the pressure of the flood water, closing off the 8m wide entrance to the studio.  It is the first time we need to install an SCFB (Self-Closing Flood Barrier) to keep water inside a building instead of outside.

Later this year a test will be done in order to prepare the studio for the first recording scheduled for January 2019.

 

Activation of Self-Closing Flood Door in Paulatem !

Monday, May 28th, 2018

 

The 4m wide and 0,6m heigh autonomous flood barrier was installed in 2017 after the homeowners experienced two flood incidents. Water from the surrounding hills passed through their house on both occasions.

Yesterday’s (24 May) heavy rainfall filled the streets with flood water which activated the flood barrier, preventing the house from flooding. The homeowners were not present at the time. The neighbours made the photo.

The Self Closing Flood Doors: a preview of the world’s longest buoyant flood barrier

Thursday, October 27th, 2016

At the end of September the Self Closing Flood Doors (SCFD) were installed and tested at the museum. These are a preview of the world’s longest buoyant flood barrier that will soon be installed at the port. (more…)

Europe-wide flood losses to ‘increase four fold’ by 2050

Tuesday, March 4th, 2014

According to the most accurate model yet developed, flood damage losses across Europe are expected to increase four fold by 2050.

The scientists believe that the continent’s annual flood costs may be 2.5bn euros by the middle of the century.

Two-thirds of the projected increase in flood damage will be caused by human development, not climate change.

The study has been published in the journal Nature Climate Change.

One of the big problems for European flood disaster research has been that countries tend to do their risk assessments on their own, using different models and methodologies compared with their neighbours.

“This is not an accurate way of working,” said lead author Brenden Jongman from VU University in Amsterdam.

“We show that if you have very high flood risk in the UK there is also a very high risk in northern France, the Netherlands and some parts of Germany.”


Risk underestimated

Rather than looking at individual flood risks, the team decided to look at maximum water discharges in over 1,000 European river sub-basins, or parts of catchments.

They found that different rivers often reach dangerous levels at the same time, threatening large regions.

“If you don’t take into account these spatial co-relations then you highly underestimate the risk – there is a much higher risk than we actually think so far,” said Mr Jongman.

“We say the average annual losses are expected to increase by a factor of four between now and 2050.”

The researchers tested the model by looking at data from rivers between 2000 and 2012. From that information they estimated that annual flood losses across Europe would be 4.9bn euros per year. Reported annual losses were 4.2bn.

Using the same system, the team estimates that annual losses by 2050 across Europe would be 23.5bn euros.

Looking at the disastrous summer floods in Central Europe last year that cost 12bn euros in losses, the researchers estimate that the chances of an event like this happening in 2050 will have increased from once in 16 years to once in 10.

The scientists say that this is the first time they can look at the probability of total damages from floods across Europe.

And while climate change is an important factor, according to Brenden Jongman, it is not the critical element in their model.

“About two-thirds is caused by socio-economic growth,” he said.

“More people are living in flood-prone areas, [and] the income per capita is increasing in the dangerous areas around Europe.”


Muddy waters

Climate change cannot be dismissed and is likely to cause precipitation events to become more intense, and flood waters will likely be deeper and last longer.

While the increase in losses from floods is significant, the scientists believe that by investing in defences and mitigation, governments can limit the economic impact.

The amount of damages likely to be caused is far more than the costs of prevention, but Brenden Jongman says that political issues muddy the waters.

“The costs of these investments come up front, but the benefits of this flood protection might be in the future, not in the current government’s term.

“There may be no votes for them.”
