Hydro demolition & Hydroscabbling

NZ Concrete Contractors Association - On the Level (Dec 2021)

Hydro Scabbling (also known as concrete scabbling) is a preparation process in which our ComBlast Mobile team use UHP (Ultra High-Pressure Water Blasting/Water Jetting) at 40,000 PSI to remove the concrete's surface layer, to achieve the specified amplitude. This method prepares the substrate for additional pours or shotcrete application.


In hydro demolition, the concrete is demolished without percussion, causing no damage to steel or surrounding areas. Another advantage of hydro demolition is the lack of dust, and no sparks are produced!

One aspect of seismic strengthening is Carbon Fibre Wrapping (pictured) - which is a key strengthening component due to its high strength capacity, lightweight and low intrusive nature. Working with a structural engineer's plans, carbon fibre can be applied to internal walls, structural columns, and floor diaphragms. This ensures its future and the safety of its occupations for many years to come.
