Hydro Demolition Simply put, hydro demolition, sometimes referred to as hydrodem is a technique that uses high pressure water jetting to oversee the controlled removal of concrete. Before this was first established, many companies used traditional machine mounted and air breakers to remove concrete from steel reinforcing. However, this technique has been recognised as too destructive and is not really used now. The main disadvantages of using traditional concrete removal techniques include: -
Damage to steel reinforcing
-
Micro cracks can be created, making it weaker
-
Long term damage to the rebars and concrete
-
More expensive
-
Slow
-
Loud
As you can see from the above, this old, labour intensive method of concrete removal wasn’t great, and a chisel was often required for more delicate areas. Today, hydro demolition is a much better alternative. Some of the benefits of hydro demolition are listed below: - Minimal vibration to the operator - No loose or damaged concrete on the edge of breakout area - No damage is caused to the steel reinforcing - The removal of concrete around dense reinforcing is possible, (impossible using air breakers). - The breakout area is thoroughly washed/cleaned More information on Hydro Demolition Hydro-demolition or hydrodem uses approximately twenty litres of water per minute at a pressure of 2500 bar. This means that the physical work is still difficult and frequent breaks are required by the operator. Conventional hydro demolition therefore can, and should, only be used for small short spell jobs. For information on the services that Sabre Jetting can offer, visit
