Flood Protection System Klein Schierstedt – BT Spannschloss® and RubberElast®

To protect people and nature, Klein Schierstedt opted for a flood protection wall made of precast concrete elements with connecting and sealing technology from BT innovation.

In this small community in Saxony-Anhalt, flood protection was also improved in 2017, after the river was flooding its surroundings several times in recent years and caused chaos. Preferably dikes were meant to be built there in accordance with nature, but this was not possible in all places. The newly erected dikes were than supplemented by flood protection walls made of precast concrete elements. A total of almost 1,000 metres was required there. The client, the state of Saxony-Anhalt as well as the residents of the community were highly pleased with the result. By using the flood protection system, the tight schedule and cost specifications were met without any problems and a safe flood protection system was created.

 

BT-Flood Protection System

The patented flood protection system consists of a dry connection for precast concrete elements (solid flood protection walls), the BT-Spannschloss® and the RubberElast® crushing joint tape. During assembly, the RubberElast® is affixed to the element. It is applied by light pressure, without primer or other preparatory work. After removing the protective tape, the adjacent element is placed. With the BT-Spannschloss® it is connected and aligned while the sealing tape is highly compressed. The resulting joint is thus permanently sealed against the penetration of water. With a BT-Spannschloss® connection, a joint grouting is not necessary. The construction can be loaded immediately after bolting. In addition, the assembly can also be accomplished in cold temperatures or with precipitation. The RubberElast® sealing tape can also be installed in unfavourable weather conditions down to -10°C. With this convenient flood protection system, up to 50 meters of flood protection walls can be erected in just one day. The advantages of this prefabricated construction are obvious: weather-independent prefabrication, fast assembly and visual design options.
