Commercial and Residential Repairs

Based in Christchurch, we are experts at concrete grinding and repairs. Part of repairing floors includes levelling in preparation for grinding and polishing.

We offer a range of residential and commercial repair solutions for concrete that may be cracked or have become damaged over time. Repairing a concrete floor can be a much more affordable solution than replacing it and offers a new lease of life.

Self-levelling floor preparation is a blend of specially graded fillers, fine cement and polymers, developed as a premium smoothing and levelling compound for internal floors with irregular substrates. It is used to level the sub-floor prior to the application of floor tiles, timber flooring or decorative surface flooring.

Concrete Sealing and Grinding NZ has experience in a wide range of concrete repair solutions including:

  • Delaminated concrete
  • Fractured expansion joints
  • Stress cracks or trip hazards
  • Stained pitted concrete
  • Tilt slab repairs and skimming
  • Repairs to existing floor toppings

We have the experience and expertise when it comes to expansion joint filling. Expansion joints are placed in floors to allow for natural movement as concrete may expand or shrink as it cures. The joints are cut into the floor after the concrete is hard enough to walk on.
