Hydrodemolition is the process of using high pressure water, typically from 15,000 psi to 30,000 psi, to remove a specific depth from a concrete surface. Hydrodemolition is very effective for use in areas of deteriorated, delaminated or contaminated concrete but is also commonly used for traditional overlay work when a specific depth of concrete removal is required and the structural steel will be re-used.
The term hydroscarification or hydro-scarification is another term referring to the same process but is normally used when depths of less than 1” are required and the steel reinforcing will not be exposed. A surface prepared using hydro-demolition and hydro scarification provides the best possible bond for all types of repair material.
Hydrodemolition and Hydroscarification have many benefits and advantages over traditional methods including:
- Hydrodemolition increases the speed of concrete removal over traditional methods.
- Hydrodemolition produces a rough, irregular surface that gives your repair material an excellent mechanical bond.
- With hydrodemolition concrete is removed to a depth of your specification.
- Reinforcement is also cleaned and prepared to bond with the repair material. This saves time and additional steps.
- Reinforcements are undamaged and generally can be reused, saving you money.
- Hydrodemolition does not damage the exposed aggregate.
- Surface micro-fracturing typically caused by traditional methods are eliminated.
- Vibration and potential damage to the surrounding structure is eliminated.
- Reducing transmitted sound through the structure.
- Hydrodemolition minimizes the dust produced using traditional mnethods.
- Robotic hydrodemolition units minimize fatigue and injuries compared to traditional methods.
