the main stand of munich’s olympic stadium renovated

a survey last year revealed that the upper tier of the main stand at munich’s ‘olympiastadion’ had suffered severe weather damage. the use of road salt had corroded beams and stanchions so severely that the stand’s structural integrity was at risk. hydro-tech, the augsburg-based concrete renovation specialist, was awarded the contract to carry out the renovation work which, given the number of events held at the stadium, required them to pull off a logistical miracle. around 2,500 m² of concrete was stripped away piece by piece to make the damaged areas visible while a further 45 m³ of concrete had to be removed from the stanchions and beams in order to renovate the dilapidated core irons.
to carry out the renovation work on germany’s second largest stadium, hydro-tech used the 2,500-bar falch trail jet 100 maximum pressure water jetting device. hydro-tech were impressed with both the strong stripping performance and high reliability of the falch devices. hydro-tech used the specially designed slide assembly for the gutters whilst some 45 m³ of concrete was removed using the falch hyjet nozzle.
