Water Blasting Services

From a home driveway to a factory floor, we water blast surfaces of every size across Christchurch and Canterbury. Our trained crews turn up on time, work to a clear quote and send before and after photos, so you can see exactly what you paid for.

We can work after hours or around your staff, customers and tenants, so your site keeps running while we clean.

What we water blast

Driveways and paths: removes oil, dirt, moss and slippery build-up.
Concrete and car parks: brings tired, stained surfaces back to life and makes them safer to walk on.
Walls and buildings: clears dirt, mould and grime from exterior walls and cladding.
Roofs: removes moss, lichen and debris and prepares roofs for painting.
Swimming pools and surrounds: clears algae and grime from pool decks and surrounds.
Factories, warehouses and yards: handles large industrial floors and yard areas, in one visit or on a regular schedule.
Paint preparation: strips loose paint and dirt so the new coat sticks.

Why choose Amarco for water blasting

Trained crews. Our teams are NZQA-certified and highly trained, and we have specialist height and rope access skills for hard-to-reach areas.
The right job for the surface. Concrete, painted walls and roofs all need different treatment, so we match the method to the surface rather than blasting everything the same way.
Any size of job. Ten trucks on the road means we can take on a small driveway or a large commercial site.
Clear communication. You get a straightforward quote, a confirmed time, and photos when we finish.
Safe and tidy. We follow strict health and safety procedures on every job.

Questions we get asked

Will water blasting damage my surface? Not when it’s done properly. We choose the method to suit the surface, and we’ll tell you if something needs a gentler clean instead.
How often should I have it done? It depends on the surface and how much shade or traffic it gets. Commercial sites often book a regular clean. We can suggest a schedule when we quote.
Can you work outside normal hours? Yes. We regularly work around tenants, staff and customers.
Do you do small jobs? Yes, from a single driveway to a whole site.
