Fix the surface, extend its serviceable life
Concrete fails from the outside in: water gets in, reinforcement corrodes, surfaces spall and crack. We repair the damage (patching, crack injection, resurfacing) and then protect the concrete against the conditions that caused it, with sealers and coatings matched to the exposure. The aim is to fix the surface and extend what's underneath, not just cover it over.
Industries & environments
Warehousing & industrial
Worn, cracked, and spalled slabs in high-traffic storage and plant.
Car parks & structures
Structural concrete exposed to traffic, weather, and water ingress.
Commercial & retail
Floors made sound and level before a new finish goes down.
External & civil
Paths, ramps, loading areas, and hardstand exposed to the elements.
Water & wastewater
Tanks, channels, and structures under constant moisture and chemical attack.
Remedial & existing buildings
Ageing concrete assessed, repaired, and protected against what's wearing it.
Concrete fails from the outside in.
Spalling
Water's way in. Cracks let moisture reach the reinforcement and start the corrosion that breaks concrete apart from within.
Corroded reinforcement
The root of most concrete failure. Once water reaches the steel it rusts and swells — so repair has to treat the reinforcement, not just the concrete around it.
Reinstatement
The damaged section cut back to sound concrete and rebuilt, bonded to what's sound rather than smeared over what isn't. This is where the slab is made structural again.
Levelled & repaired concrete
The same slab, made good — the section reinstated, the surface ground and levelled, ready for protection.
Protective coating
Seals the repaired surface against water, chemicals, and dust — keeping out the conditions that caused the damage in the first place.
Concrete doesn't fail all at once. Water gets into cracks, reaches the reinforcement, and corrodes it — the steel expands, and the concrete above it spalls away. Left alone, the damage spreads and the surface keeps breaking down.
Repair means dealing with the cause, not just the surface. The damaged concrete is cut back to sound material, corroded reinforcement is treated or replaced, and the section is reinstated with a repair mortar matched to the substrate. From there the surface is ground, levelled, and given the falls it needs — then protected with a coating or sealer so the conditions that caused the damage can't start it again.
Cover it over without fixing what's underneath and it comes back. The repair is only as good as the preparation beneath it.
Crack & spall repair
Cracked and spalled concrete cut back to sound material, corroded reinforcement treated, and the section reinstated with a repair mortar matched to the substrate — dealing with the cause, not just the surface.
Grinding, levelling & screeding
Surfaces ground and prepared, low spots and falls corrected, and levelling screeds laid to give a sound, even base — whether for a new finish or to correct a floor that's moved.
Protective coatings & dust-proofing
Sealers and coatings that protect repaired concrete against water, chemicals, and wear, and dust-proofing treatments that stop bare slabs from shedding dust into the space above.

Landscaping and Outdoor Areas
We do outdoor surfacing, built for New Zealand conditions: pool surrounds, driveways, patios, paths, and entertaining areas.
Commercial
We work with construction teams, architects, specifiers and property owners on technically demanding projects. Waterproofing systems, protective coatings, anti- slip treatments on new surfaces - specified, applied, and documented.
Residential
Whether the work ends up on show or behind a wall, the standard doesn't change. High-impact areas get the attention they deserve. How it looks when we're done is part of how we think on every job - not something you need to ask for.
