Structural filling of cracks, Bikini Berlin
During the renovation, the Bikini House was completely gutted and stripped down to its concrete structure. To restore the load-bearing capacity of the ceiling construction and the supporting pillars, cavities/voids were filled and cracks were bonded together in a structural manner.
Solidification of the ceiling structure
Structural filling of cracks – for improved load-bearing capacity
1 - Locating the reinforcement
2 - Small-diameter drill holes
3 - Mineral patching
4 - WEBAC 4110 epoxy resin injected at low pressure
Consolidation of the pillar structure
Structural filling of cracks and cavities – for imporved loadbearing capacity
5 - Low-diameter drill holes
6 - Mineral patching
7 - WEBAC 4110 epoxy resin injected at low pressure
The Bikini House was built between 1955 and 1957. The low-rise building has six floors and is 200 meters long. The lower part originally housed shops, while the upper part contained production, administrative, and office space. The name was quickly coined: an open-air floor on the second floor with a view of the greenery divides the building and reminded viewers of a bikini. The Bikini House was closed in 1978, renovated from 2010 to 2014, and is now known as “Concept Mall Bikini Berlin,” a shopping center with stores, a cinema, and restaurants.

WEBAC 150 is a versatile PU injection foam resin (SPU) that is particularly valued for its safe and easy application. Upon contact with water, it cures with significant expansion to form a surface-tight, firm-elastic foam with a very fine-cell structure. This makes it suitable for the rapid, temporary closure and sealing of pressurized water-bearing cracks, cavities/voids, and leaks in building construction, civil engineering, bridge construction, and tunnel construction.
PU Injection Foam Resins
WEBAC® 157
- Classic Line
View detailsWEBAC 157 is an elastic PU injection foam resin (SPU) with a very fine-pored foam structure. Upon contact with water, this low-viscosity material forms a surface-tight, adaptable foam. It is suitable for temporarily closing, sealing, and filling cracks, cavities/voids, and gaps in masonry, concrete, and natural stone—e.g., in shaft construction and water management structures—and can also be used where there is limited movement of structural components.
Epoxy Injection Resins
WEBAC® 4120P
- Classic Line
View detailsWEBAC 4120P is a low-viscosity epoxy injection resin that penetrates even the finest cracks. It cures to a tough, strong finish and, thanks to its high tensile strength and bond strength, enables a durable, structural connection, even under dynamic loads. WEBAC 4120P is used to close, seal, and force-fit cracks and is particularly suitable for components subjected to dynamic loads, such as the foundations of wind turbines.
