Strong flood protection partnerships

Floodprotection-Summit 2015

As one of the leading industry insurance brokers, BDJ (www.bdj.de) invited risk experts and decision-makers to a flood prevention summit in Herborn in 2015. Collaborating with Condor Sicherheit (www.condor-sicherheit.de) , presentations were held on risks and best practice solutions in risk management. The summit concluded with an impressive live demonstration of a mobile dike constructed through a river. Drones were used to photograph and film the event. Participants thus came away with a comprehensive insight into modern crisis management, safety engineering and preventive measures.

As a strategic partner, Condor offers your customers full-time coverage against flood risks, where necessary. Mobildeich products are used due to their technical application qualities.

The practical demonstration of the simple set-up and take-down of a mobile dyke at the BDJ summit impressed the experts from the insurance industry, fire service and the former head of the flood protection centre in Cologne, Reinhard Vogt. In addition, the dyke's resistance to vandalism or flotsam in the water was tested, with impressive results: a cut made with a knife could be largely sealed within seconds using simple methods.

Monitoring drones provided comprehensive images of the dyke's location. The preparation, construction and functioning of the mobile dyke were filmed from a bird's eye view by Aerialtronics drones equipped with HD cameras belonging to CONDOR’s partner UAV International GmbH (www.uavinternational.de). In the event of floods and emergencies, the drones transmit HD live images of the affected locations to local and decentralised management units to aid in the organisation of rescue workers. These drones are also equipped with thermal cameras and can be used to support rescue workers during avalanches etc. For industrial customers and insurers, the possible applications for preventative building surveys, technical inspections and intervention support are also important. The drones are also equipped with a powerful loudspeaker, making them ideal for support during events and emergency operations. All of these services are offered by CONDOR together with UAV International GmbH.

Flood protection

Flood rescue mission 2013

Several thousand metres of mobile dykes were used successfully during the floods in Germany in June 2013. At certain locations, the capacity was maxed out at the full water level, for example at Kulturstiftung Dessau-Wörlitz, where the height of application extended up to 1.50m.

At other locations, dyke heights were increased at short notice where the water level was approx. 1.60 m deep at the mobile dyke.

The fire brigade of the Lahn-Dill district employed dyke modules at short notice at the Deutsches Eck in Coblenz. The fire brigade were thus able to secure a large area that would have been swept away in flood waters without dyke protection.

Further location included Wolfenbüttel and Rosenheim. In Magdeburg, a mobile dyke was used to protect the broadcasting studio of the MDR from flooding. Dedicated in 1999, the broadcasting studio located on the island of Rotehorn in the Elbe was built as a counterpart to the Magdeburg Cathedral, located on the opposite side of the Elbe. Operations at the studio, including broadcasting, editorial and management activities, were able to continue unhindered thanks to the mobile dyke.

Disaster control/oil protection

Mellum: Use at Wadden Sea national park

A destination best reached by landing craft: the island of Mellum is located in the middle of Wadden Sea. MOBILDEICH was contracted by NLWKN to develop a protection plan for the event of an oil spill. The bird sanctuary island must be protected in the event of an oil spill originating from the North Sea or the Jade river. The challenge here was finding an effective means of defending against the water masses of the tidal current in the soft bed of the tidal flats. Over the course of a day-long exercise, vehicles, personnel and equipment were transported to the island to seal off the 70-meter-wide main watercourse from the sea. The island is usually uninhabited.

In addition to representatives of NLWKN and the administration of the national park, the Cuxhaven central command for maritime emergencies, the Federal Agency for Technical Relief, the conservation group Mellumrat, the police directorate of Oldenburg, the district of Friesland and Wesermarsch, Red Cross and the company Buhr were among the participants and observers.

The mobile dike was erected in two sections: conventionally (by hand) pictured on the left, and,pictured on the right, using an uncoiling device specially designed for the trailer of a Hägglunds track vehicle. The mobile dyke module was continuously unwound and laid onto the bed of the tidal creek while two pumps transported the water from the floods to the dyke body at 1,500 l/min. The lower base modules were filled to a dyke height of 1.40 m in around 50 minutes. The upper tube was filled with air for demonstration purposes.

The dyke height on the main length was 2.60 m and the length of the dyke chain was approx. 80 m.

Temporary reservoirs

Mobile pond for 8,000 m³ water retention

A large quantity of water has to be openly stored and kept accessible in a short amount of time - a typical industry application at first glance? What is unusual are the specifics of this method of mobile water retention: a mobile dyke was erected as a "mobile pond" in three condensed building phases over a short period of time.

An earth wall was initially built to enclose and secure the site at the customer's request. A three-layer drainage floor with a 5,000 m2 sealing membrane was subsequently laid in the basin. In order to make transportation easier, the drainage floor was delivered in four separate pieces and welded together on site.

In the final stage of construction, the body of the basin was laid out with a 330-meter-long ring dyke made from MD 93-3 modules. The edges of the sealing membrane were folded back and laid over the filled mobile dyke.

The entire basin was constructed in only 3 work days (!).

Disaster control/oil protection

Tidal creek in Neßmersiel

Even in the lowlands the currents can be torrential: what looks like a normal river in pictures is a tidal creek in the mud flats with extremely soft and dense ground. The chances of keeping your rubber boots on your feet when walking through it are extremely slim.

The ideal terrain for putting the mobile dyke to the test again: neither observers nor the construction team could predict with any certainty whether construction in the marshy tidal creek was technically feasible and whether sealing against the water masses of the tidal currents would be successful.

This particular location was chosen for the construction of a mobile dyke at the invitation of the Lower Saxon State Department for Waterway, Coastal and Nature Conservation (NLWKN) at an expert meeting in Neßmersiel. The impact of the tides and the unusual soil characteristics are typical of the Wadden Sea and testing new protective concepts provides valuable insight for future protection in the event of disasters.

A 30-metre-long mobile dyke was transported to the site with a Hägglunds tracked vehicle. The dyke body was first connected to a pump and then the dyke was rolled out. The employees of NLWKN had constructed three reservoirs with the previous flood waters to provide sufficient water for filling.

Due to the weight of the water filling, the mobile dyke was already stable when it was rolled out through the depression of the tidal creek. In order to better climb the step on the opposite side of the bank, the spool wheels were temporarily removed from the dyke roller. The increasing water pressure in the dyke body helped with unwinding the tube – and ultimately allowed the opposite bank to be climbed.

After roughly 2 hours, the dyke and its orange sealing membrane were secure and stable at the bottom of the tidal creek. The experts present were very satisfied with the protection measure and are planning another experimental construction at a tidal creek on the island of Mellum that is three times as large.

Flood protection/dyke height increase

Kulturstiftung Dessau-Wörlitz (KSDW)

Mobile dyke length: 1.7 km

The Kulturstiftung Dessau-Wörlitz acquired a MOBILDEICH to protect its historical parks. The decision to acquire the 1.7 km mobile dyke protection system was made in agreement with the Saxony-Anhalt state department for flood protection and water management, the state office for the preservation of monuments and the state administration. No other system for flood protection fulfilled the high safety and flexibility requirements set by the committee of experts.

In the event of flooding, a ring dyke located on the UNESCO World Heritage Site will be increased by up to 1.60 m in height to protect the unique landscape designed by Leopold III Duke of Anhalt-Dessau and his advisor Friedrich Wilhelm von Erdmannsdorff from the floods.

A mobile dyke with heights of up to 2.10 m protects a stud farm located at the mouth of the Mulde river.

The garden around the Luisium has lost none of its beauty, as MOBILDEICH can be erected at such high-profile locations without any construction equipment.

Particular care was given to protecting the trees located on site. Specially adapted sealing members for trees were used to seal the system at several locations.

Water construction site

Fürstenberg (Havel) – Draining of a construction site for a fish/canoe passage

MOBILDEICH was brought to the site in Fürstenberg in an estate car with trailer (1).

Image (2) shows the construction site located in the urban greenery. In the next picture, Mobildeich is placed in the middle of the river using a construction crane. The bank and slope area is uneven and is blocked by stones and poles. Here, MOBILDEICH proves its particularly good sealing properties on various substrates.

In the picture on the bottom right, the dyke has already been completely laid out through the water. A weir at the rear was then opened, and the construction area was dry within 15 minutes. In the pictures below, the accumulated water depth of 1.40 meters is easy to see. Construction was carried out for three weeks behind the dyke without any leakage or washouts occurring. Apart from daily visual inspections, no work had to be carried out on the dyke. After the construction period, the site was flooded and the Mobildeich was dismantled.
