Take the concrete off. Leave the steel intact.
One contractor from four litres a minute to 45,000 psi. Hydrodemolition, coating and corrosion stripping, line marking removal and shutdown cleaning, out of depots in Auckland, Wellington, Taranaki and Taupo.
Before it beats another contractor, it has to beat a jackhammer.
A breaker gang gets through a reinforced slab at a quarter of a cubic metre an hour per operator, and every blow it lands travels into the structure you are keeping. Water at 20,000 psi and above removes sound concrete faster, leaves the reinforcement clean and in place, and puts no vibration or micro-fracturing into the substrate that stays.
How the two methods compare| Element | Depth | Breaker | Water |
|---|---|---|---|
| Reinforced slab | 50 to 150 mm | 0.19 to 0.26 | 0.93 to 1.49 |
| Reinforced slab | 150 to 300 mm | 0.11 to 0.21 | 0.93 to 1.49 |
| Reinforced wall | 50 to 150 mm | 0.18 to 0.28 | 0.93 to 1.49 |
What we remove
- Concrete removal and hydrodemolitionTake concrete off and leave the steel behind it intact.
- Coatings, paint and corrosion removalStrip to bare substrate without touching the substrate.
- Road markings and surfacesMarkings, rubber, bitumen and spills off carriageway and runway.
- Plant, tanks and pipeworkShutdown cleaning where the window is the constraint.
- Hydro excavation and vacuum recoveryDig around live services without a strike.
- Septic tank cleaningDomestic and commercial tanks, Rotorua and Taupo.
We've used Aquamax for 15 years on our annual shuts. I continue to be impressed with their project planning, health and safety management and the quality work delivered for us.

Plant
Nine pumping units from 4 litres a minute to 45,000 psi, with the robots, lances and vacuum recovery that go with them. Every published pressure and flow figure is on one page.
