As well as civil engineering, an important area of application for our suction technology is building renovation. Bulk materials, building materials, spoil and rubble are removed effectively and quickly. Other demanding applications in this sector are the exposure of foundation walls, external walls, tanks, earth bunkers and soakaways as well as cellar renovation, lowering of cellars and the cleaning of flat roofs. Hose extensions allow difficult-to-access areas to be reached easily, and large suction distances to be overcome without any problems.
