marbach city walls

the historic city walls in marbach on the neckar had to be renovated. grime, dirt and other deposits had to be removed. another requirement was to reveal the gaps between the stones in the wall, in order subsequently to re-point them. the falch technology was chosen because of the large area to be covered at the lowest possible cost. in total, an area of approx. 600 m² was blasted in 3 days.
