When renovating and maintaining structures, buildings, monuments and facades, it is not uncommon to be faced with the challenge of having to remove damaged concrete in order to re-shutter these areas in the further course of the work and then pour new concrete. With water jet systems, concrete can be removed layer by layer up to the complete exposure of the reinforcement. Systems can be combined and adjusted in such a way that different water jet strengths are possible and a correspondingly large or small amount of material can be removed at once. A spot-jet nozzle or a MASTERJET rotor jet can be used for this purpose.High-pressure systems and application systems from Hammelmann form a complete package for cost-effective operation.
Gentle exposure of iron or steel reinforcements as well as structural steel meshes is a major advantage when processing concrete with modern water jet systems. In this process, only the damaged concrete is removed until the reinforcement is partially or completely exposed. The steel remains completely undamaged after exposure and the surface to be processed is optimally prepared for further work steps. Water jetting also enables precise work on specific areas of a concrete surface. This enables precise exposure and even complete breakthroughs in the wall.
