Construction of a biogas plant - BT-Spannschloss® (turnbuckle)

In Jemgum the commissioning of a 75kW biogas plant was planned. In this project the BT-Spannschloss® was used to connect the prefabricated elements. The BT-Spannschloss® made a fast and problem-free assembly possible with an average assembly time of only 20min per element. This shortened the assembly time from three days to one day. The BT-Spannschloss® was able to meet the high static requirements without any problems. Just 2 months later, the system was put into operation by its owner.

Flood Protection System Wittenberge - BT-Spannschloss® and RubberElast®

The high water level posed a special challenge in Wittenberge. This problem was solved with a combination of BT-Spannschloss® and RubberElast® for a flood protection system.

Sealing of working joints between floor slab and element walls in house building

Concreting in construction phases – SynkoElast®

SynkoElast® shuttering profiles were used for concreting a large floor slab in several construction phases. The profiles were fixed to the reinforcement and the concrete of the first construction phase could be filled in. After removing the protective tape, concreting could continue immediately.
