during the renovation of a sprinkler basin measuring approximately 17 m × 17 m × 2.70 m for the internal fire water supply in hechingen, the workers faced several major challenges: not only did they have to comply with the specified level of safety, noise level and oxygen demand. 

there was also a challenging access point, around 20 m long. it led from a car park via a basement staircase, then through a small 80 cm × 80 cm manhole and via a ladder into the basin. a precise, careful approach and an efficient, easily planned implementation were required.
 

falch solved these challenges with transformation and automation: a trail jet 125 and a trail jet 30 outside the building ensured a system pressure of 2500 bar and a delivery rate of 24 litres/minute. combined with a hand lance and the collapsible surface rob 250, the concrete on the wall, supports and floor in the basin was roughened. the robot achieved a performance of about 1 m²/minute, while the hand lance managed around 0.3 m²/minute. in total, around 450 square metres of coating area were treated in the shortest possible time. the dirty water was treated on site with the base filt 50 big bag. 

falch was the clear first choice. the expert advice, the project package put together and the reliable service made a simple solution with an optimal result possible.
