Service · Hydro Demolition & Scabbling
Precise hydro demolition and scabbling.
Ultra-high-pressure water blasting from 3,000 to 40,000 PSI for the efficient removal of concrete, asphalt and grout, clean, controlled and precise, without damaging the surrounding surface or the reinforcing that stays.
Plain-English overview
What it is, who it’s for, when to call us.
Hydro demolition and scabbling are advanced surface preparation techniques. Using ultra-high-pressure water blasting at up to 40,000 PSI, we remove concrete, asphalt and grout to achieve the aggregate profile the engineer wants, preparing the surface for shotcrete and setting the stage for an optimal repair. Because it’s water, not impact, it removes exactly what needs to go and leaves the sound concrete and reinforcement behind, undamaged and ready to build on.
Call us when you need selective removal on a difficult substrate, when mechanical breaking risks the surrounding structure or the rebar, or when an engineer wants a clean, well-prepared surface for repair or overlay. Our units range from 3,000 to 40,000 PSI, which makes the same crew ideal for creating anti-slip surfaces and preparing floors for high-traffic environments. We work this in alongside our concrete repair teams, who step in for the shotcrete, so removal and reinstatement run as one job.
Common use cases
Where hydro demolition comes in.
Ultra-high-pressure water blasting
Using UHP water blasting from 3,000 to 40,000 PSI to remove tough materials and contaminants from surfaces.
Hydro demolition
Employing high-pressure water jets to selectively demolish concrete without damaging rebar, ideal for precise and controlled removal.
Concrete scabbling
Using UHP water blasting to roughen concrete surfaces, creating a better bonding profile for overlays, coatings or repairs.
Stripping & surface preparation
Stripping coatings, rust and debris with UHP water blasting, ensuring optimal adhesion for new applications.
Cold cutting
Accurately cutting through materials of different thicknesses, ensuring precision without affecting the integrity of the material.
Pipe jetting & heat exchanger cleaning
Industrial-strength cleaning of piping and heat exchangers, removing blockages to ensure the efficient flow of water or air.
Why Connect
Removes the concrete, keeps the structure.
UHP is a highly specialised skill that demands extensive training and strict health and safety compliance. By engaging Connect, you can be assured the work is carried out to the highest quality and safety standards, on both planned and emergency works, removing exactly what needs to go, protecting what stays, and handing straight over to the repair team.
