Construction, Building and Civil Engineering
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.
Restoration and maintenance with hydrodemolition
Gentle and precise work without damaging the reinforcing bars.
No vibrations on adjacent surfaces.
Adjacent surfaces are not damaged.
No chemical loads on the surface.
No thermal stress on the surface.
Less wear as no caulking tools are used.
Gentle, pinpoint exposure of the reinforcement up to the breakthrough of the surface
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.
Application examples from practice
- Layer by layer removal of various concrete layers
- Gentle, precise exposure of the reinforcement up to the breakthrough of the surface
- Renovation of wind turbines / Spot removal of damaged concrete
- Remove contamination from a wide variety of components quickly and predictably
Roughening a wide variety of surfaces - from fine to rough
A high-pressure spray gun can be excellently used in combination with a MASTERJET rotor jet for roughening different concrete surfaces. Equip your nozzle with 2, 3, 4 or 6 inserts and decide for yourself the degree of roughening. The water pressure is distributed evenly over the number of nozzles fitted. With 6 nozzle inserts, you therefore exert significantly less pressure on the surface to be processed than with 2 nozzle inserts. According to this rule, you can decide for yourself whether you want to roughen the surface more finely or coarsely.
Application examples from practice
- Roughening concrete surfaces - from fine to coarse
- Roughening of roads and roadways
- Decoating of tunnel and interior walls
- Derusting and decoating of surfaces and substrates and protecting them from corrosion
