Refurbishment of Gazela Bridge, Serbia: Clients were impressed by Sika’s sound knowhow and excellent service.
This famous wooden bridge is over 200 years old and was built with an original design capacity of 12 tons. Local residents wanted to preserve the historic structure, yet it needed structural upgrades. With minimal visual impact, Sika’s structural strengthening solution of this timber bridge was part of a long-term study and was one of the first Sika CarboDur® strengthening projects on wooden structures.
For the concrete repair/rehabilitation and protection of the interchange various Sika products were used.
The repair solution chosen included the installation of a new central bridge pier to support two existing outer piers.
