Hydro-Demolition is a technology that uses extremely high pressure water jets that are capable of removing concrete while not damaging the rebar. The practical application of this technique makes it an extremely effective and efficient method of concrete removal. This is due to two main factors, one being the direct impact of the water jet on the surface. The other is the porous nature of concrete, the high pressure water is forced into the tiny cavities and cracks within the concrete mass, causing it to fracture and split.
Selective Material Removal
The variable parameters of the technique, water pressure, jet size and speed of application, make it possible to demolish and remove concrete in a very precise and controlled way. These variables enable selective removal of deteriorated or de-laminated concrete, as the jet stream penetrates the cracks and faults in the degraded material more quickly, leaving the sound concrete intact.
