Most of Farrell Concrete’s work is in concrete grinding and polishing but the team are also experts at remedial work, fixing things that have gone wrong or preparing surfaces for further renovation.
Grind and seal is a versatile finishing option that delivers a clean, modern look while protecting the concrete surface. Farrell Concrete offers all exposure levels, from a light salt and pepper grind through to a deeper, more pronounced aggregate reveal. After grinding, the floor is sealed with high quality coatings selected specifically for New Zealand conditions.
This process enhances the natural characteristics of the concrete while creating a durable, easy to clean finish suitable for homes, garages, workshops and commercial spaces. Grind and seal is a strong choice when clients want the look of polished concrete with a cost effective protective layer.
For clients wanting a refined, long lasting finish, Farrell Concrete provides full concrete grinding and mechanical polishing services. This process restores or upgrades new and existing floors, removing surface imperfections and producing a smooth, high clarity finish.
Grinding and polishing brighten interior spaces, highlight aggregate and strengthen the concrete surface for decades of use. It is ideal for homes wanting a modern, seamless look, as well as commercial environments that require durability without compromising on design.
Cream polish is a cost effective way to rejuvenate an existing slab while maintaining the authentic character of the original concrete surface. Instead of cutting deep to expose stone, the process preserves the top layer of the slab, resulting in a soft, cloud like finish with subtle movement and colour variation.
Farrell Concrete densifies, hones and polishes the slab to achieve the desired sheen level. Because every slab is different, each cream polish finish is unique, making it a popular choice for renovations and architectural homes seeking a warm, natural aesthetic.
Surface preparation is essential for achieving long lasting results, whether installing a new floor finish or refreshing an existing one. Farrell Concrete provides thorough prep work including the removal of grout, vinyl, glues and coatings, as well as levelling and cleaning the surface to create a strong foundation for the next stage of the project.
This preparation ensures new flooring systems adhere correctly, perform reliably and maintain their appearance over time.


Bush hammering creates a rugged, slip resistant surface by mechanically impacting the concrete to expose a natural, stone like texture. This makes it ideal for improving safety, enhancing visual appeal or preparing concrete for coatings and overlays.
The technique is widely used in high traffic rural settings such as packhouses, cowsheds, cattle yards and horse or boat areas where additional grip is essential. It is also suitable for remedial work, including rain damaged slabs, delamination repair and adhesive removal.
In residential and architectural applications, bush hammering adds character to pool surrounds, patios, stairs, walkways, ramps, block walls and pavers. The result is a durable, low maintenance surface with a distinctive natural aesthetic that performs well in Northland’s environment.
