Small cracks rarely stay small in Auckland conditions
A hairline crack in a slab, wall, column or barrier looks harmless. But Auckland's coastal air and humid conditions push moisture into the concrete, the reinforcing steel begins to corrode and expand, and what started as a cosmetic mark turns into spalling, loose concrete and genuine structural repair work.

That progression is expensive to ignore. Damaged concrete affects the strength of the structure, the appearance of the building and, for commercial and body corporate sites, the compliance conversations that follow. Patching over the surface without understanding why the concrete moved simply hides the problem until it returns.

Prime Solid Plastering, based in Mount Wellington, carries out concrete crack repairs across Auckland for homeowners, developers, body corporates and trade clients. Every job starts with an investigation into the source of the cracking, so the repair method matches the actual cause. Our ICRI-trained concrete repair capability, Sika and Mapei repair systems, and five-year workmanship warranty on patch repairs give you a result built to last.

Crack injection, grouting or patch repair — matched to the cause
Not every crack needs the same treatment. Some are best resolved with concrete crack injection, which fills and bonds the crack through its depth. Others call for structural grout repair, precision grouting or dry-packing, particularly under columns and steel fixings. Shallow surface damage may only need the area cut back, rebuilt and finished.

We assess which approach suits your concrete before we quote, using Sika and Mapei repair and levelling systems chosen for durability rather than convenience. Where reinforcing steel needs repair, specialist steelwork is arranged separately so that part of the job is handled by the right trade.

The benefit is a repair that holds. Choosing the correct method the first time avoids repeat cracking, repeat scaffolding and repeat cost.
Spalling, moisture and restoring the look of the surface
Spalling and loose concrete are usually signs that moisture has reached the reinforcing steel. We remove the deteriorated material, treat the cause of the water ingress and rebuild the area so the structure regains its strength and the surface is protected against further moisture.

Appearance matters too, especially on visible façades, barriers and precast panels. We match the colour and texture of your existing concrete as closely as possible. Honest answer: a repair will never be absolutely identical to decades-old concrete, but a well-executed repair blends in far better than a rough patch.

For uneven or cracked interior floors, our concrete floor grinding, levelling and polishing work delivers a clean, even finish ready for use. Residential concrete crack repairs in Manukau, commercial concrete crack repair across Auckland and body corporate remedial work are all handled with the same standard of preparation and quality checks.

Cracking is usually a symptom of something else, such as moisture reaching the reinforcing steel or movement in the structure. Every job begins with an investigation into the source of the cracking so the repair method matches the actual cause, rather than simply covering the surface and allowing the problem to return.

Depending on what the assessment shows, we use concrete crack injection to fill and bond a crack through its depth, structural grout repair, precision grouting or dry-packing under columns and steel fixings, or cutting back and rebuilding shallow surface damage. We work with Sika and Mapei repair and levelling systems, and our team holds ICRI-trained concrete repair capability.

Yes. Concrete patch repairs carry a five-year workmanship warranty, and repairs are designed to restore both the strength and the appearance of the concrete.

We match the colour and texture of your existing concrete as closely as possible, which makes a considerable difference on visible façades, barriers and precast panels. To be honest, a repair will never be absolutely identical to decades-old concrete, but a well-executed repair blends in far better than a rough patch.

Where deteriorated concrete is removed, we treat the cause of the water ingress and rebuild the area with durable repair materials. If the reinforcing steel itself requires repair, specialist steelwork is arranged separately so that part of the job is completed by the right trade.
