Flood protection system Klein Schierstedt - BT-Spannschloss® and RubberElast®

To protect people and nature, the decision was made in Klein Schierstedt in favour of a flood protection wall made of precast concrete elements with connection and sealing technology from BT innovation.

In this municipality in Saxony-Anhalt, flood protection was also upgraded in 2017 after the river had burst its banks several times in recent years and wreaked havoc. Preferably, dikes were to be built there in harmony with nature, but this was not easily possible in all places. So the newly constructed dikes were supplemented with flood protection walls made of prefabricated concrete elements. A total of just under 1,000 metres was required there. The client, the state of Saxony-Anhalt, and the residents of the community are highly satisfied with the result. Through the use of the flood protection system, the tight deadline and cost requirements were met without any problems and a reliable flood protection facility 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® squeeze tape seal. During assembly, the RubberElast® is glued to the component. The application is done by light pressing without primer or other preparatory work. After removing the protective strip, the adjacent component is placed. The BT turnbuckle is used to connect and align it, strongly compressing the sealing tape. The resulting component joint is thus permanently sealed against water penetration. No joint grouting is necessary with a BT-Spannschloss® joint. This means that the structure can be loaded immediately after bolting. In addition, the installation can also take place at low temperatures or in precipitation without any problems. The RubberElast® sealing tape can also be installed in adverse weather conditions down to -10°C. With this convenient flood protection system, up to 50 metres of flood protection walls can be erected in just one day. The advantages of this prefabricated construction are obvious: weather-independent prefabrication, rapid assembly and visual design options.
