Concrete Polishing  & Concrete Grinding

Welcome to NZ Grinders – the home of New Zealand’s fastest, most efficient concrete polishing service.

Let’s face it – carpet, tiles and lino can all be very expensive flooring solutions, especially for large areas. Rough concrete left unpolished is a hazard and an eyesore.

Polished concrete floors offer a finishing solution that is visually impressive, low-maintenance and highly cost-effective.

The Benefits

Concrete polishing allows a range of bold design options. Our floor coating solutions easily protect your floor from damage over the long term, and the solutions we offer are clean and eco-friendly (we even recycle the concrete dust).

Our HTC-1500 unit – the only one of its kind in New Zealand – can cheaply and effectively polish large areas of floor in very little time. This unit gives us a unique advantage over other NZ concrete grinding companies – none of their equipment matches the speed and efficiency of this cutting-edge machine.

The bottom line is a low-cost, large-scale solution which will solve your flooring problem in a much shorter time span than laying carpet, tiles or lino.

Unmatched Technology

Our range of equipment – from the HTC-1500 ride on grinder to our more compact grinders and polishers – allow us to tackle a range of jobs from large industrial warehouses and commercial spaces down to smaller jobs like garages, kitchens and bathrooms.

All our customers receive the same care and attention to detail we pride ourselves on, regardless of the project size.

In addition to concrete polishing we pride ourselves on offering top-shelf anti-slip coatings, epoxy coatings, food-safe flooring, block honing and a range of other floor coating options.

A Proven Reputation

At NZ Grinders we combine industry leading expertise with a painstaking attention to detail to ensure we deliver you best-in-the-business floor polishing solutions.
