As a result of high loads (mechanical / chloride), damage (cracks / spalling) became visible on the floors of the underground car park. In order to get an exact picture of the damage, the underground car park was inspected, and the damage was catalogued.
The client commissioned a trial repair to verify the repair calculation and to determine a repair technology appropriate to the object and the damage. The “W” repair principle was to be used, as well as the removal of salts from the columns. In addition, moisture and corrosion monitoring systems from BS2 were used as a safeguard.
