The wide steel profiles in the passage, which were to protect the edges of two adjacent expansion joints, did not pass the test. The wide steel profiles were deformed, the concrete along the profile-concrete boundaries began to crumble and the passage through them became very burdensome.
The only effective repair was to remove the steel sheets, widen the expansion joints, clean the repair site and install the HC-SINUS Slide repair sinusoidal repair profiles exactly over the expansion joint gaps. Continuous support under the wheels and a 100% homogeneous passage is provided.
