Structural reinforcement, Pergamon Museum Berlin
The Pergamon Museum is part of the Berlin State Museums and is one of the most significant buildings on Museum Island. As part of the structural reinforcement work, the renovation efforts focused, among other things, on the old cellar vaults and adjacent load-bearing elements.
Structural bonding issues were identified at the junction of a load-bearing wall and the ceiling. The affected wall was approximately 1.20 m wide and 15 m long. Core samples revealed large cavities/voids and bonding failures between the grout, cement paste, and masonry.
Initial grouting work began as early as mid-2017, Subsequently, a new concrete facing shell was installed in the old cellar vaults. The goal was to establish a structural connection between the structural elements. Since a sufficient structural connection to the ceiling could not be achieved using grout concrete followed by cement paste injection, the use of an epoxy resin was recommended based on an expert opinion. To resolve the structural issue, targeted grouting with WEBAC 4110 was then carried out.
The use of the epoxy resin reliably established the structural bond and sustainably restored the structural integrity of the component. The measure thus made an important contribution to the structural safety of the Pergamon Museum.

WEBAC 4110 is a CE-certified, low-viscosity epoxy injection resin. This allows the resin to penetrate even the finest cracks and crack branches, enabling a permanent bond in concrete and masonry structures. After application, it cures with constant volume to form a solid material with high tensile strength and inherent strength, as well as excellent edge adhesion. It is used to close, seal, and perform structural bonding of dry cracks in concrete components, as well as for injection of construction joints.
