Hydrodemolition (also known as hydro demolition, hydroblasting, hydro blasting, hydromilling, water blasting, and waterjetting) is a technique that utilizes high-pressure water to remove deteriorated and damaged concrete as well as asphalt and grout. It is effective in removing concrete from around embedded metal elements such as reinforcing steel, expansion joints, anchorages, conduits, shear connectors, and shear studs without damaging them. The process provides an excellent bonding surface for repair material and new coating applications.
Hydrodemolition offers a number of environmental benefits compared to other methods of concrete removal. It creates no dust pollution, reduces noise pollution, and the water used during the process can be collected after use to minimise any risk of contamination. Recent technological innovations allow the process of water to be cleaned and reused after hydrodemolition.
Total Enviro Solutions had been pioneering Hydrodemolition since 2015. We have made a considerable investment in the state of the art equipment from Sweden to tackle most concrete demolition or rehabilitation.
Using Aquajet Robots from Sweden and Ultra High pressure pumps operation at 1000 bar at 100 lites per minute the Aquajet Robot efficiently removes the concrete, exposing the re-bar without causing any structural damaging.
HydroDemolition applications include:
- Rehabilitation of bridges
- concrete structures
- Bridge repair
- Removing old concrete
- Removing incorrectly laid concrete.
- Warf and harbour repair
- Road repair
- Building repair
