Commissioned by De Kroon Schoonmaak, ATI Abseiltechnieken washed the windows of an apartment complex in Maarssen.Due to the building’s location by the water and its height, it was difficult to reach all around it for traditional aerial work methods. By deploying our abseil techniques, however, the windows could be washed safely and efficiently. Our rope access technicians could quickly position themselves along the facades and wash all the windows.
