Concrete Remediation

The Challenge

Failed coatings and oil contamination had compromised the concrete surface at the site. The acid-affected paint and oil spills were degrading the concrete beneath and would have undermined the performance of anything applied over the top, so the contamination needed to be fully addressed before reinstatement could proceed on a reliable basis.

Our Approach

BlastOff sandblasted the affected concrete areas to remove the damaged paint and lift the oil contamination from the surface. The abrasive process was controlled to strip back only what needed to go, exposing clean, sound concrete rather than leaving residual staining or weakened material behind. This gave a verifiable, consistent result across the treated areas, matched to what the reinstatement stage required of the substrate.

The Outcome

The concrete at Montgomerie Road was restored to a clean, uniform condition, with the acid paint and oil contamination fully removed. Vero Insurance received a verifiable surface ready for reinstatement, with the underlying concrete no longer at risk from the contamination that had been degrading it.

Lifting Acid Paint and Oil Contamination Out of a Mangere Concrete Slab

At Montgomerie Road in Mangere, Auckland, Vero Insurance needed a concrete slab brought back to a sound, workable condition before reinstatement could go ahead. The surface had failed coatings affected by acid, along with oil contamination that had soaked into the concrete rather than sitting on top of it. That distinction mattered: staining like this does not respond to a simple clean, and painting or lining over it would only trap the contamination beneath a new finish, letting it continue to compromise the concrete and undermine whatever was applied next.

BlastOff addressed the problem at its source using commercial concrete remediation, sandblasting the affected areas to strip the acid-damaged paint and lift the oil contamination out of the surface. The abrasive process was controlled so only the compromised material was removed, leaving clean, sound concrete rather than patchy staining or weakened material behind.

The result was a uniform, verifiable surface ready for reinstatement, with the contamination that had been degrading the slab fully addressed rather than masked.

For other commercial and industrial site owners dealing with oil spills, acid damage or failed coatings on concrete, the lesson from this project is that the removal method has to match the type of contamination present. Oil and acid staining behave differently to surface dirt or old paint, and treating them the same way risks an inconsistent result. A proper scoping conversation should identify what has actually affected the concrete, how deep it runs, and what condition the substrate needs to reach before the next stage, whether that is a coating, a membrane or simple reinstatement, so the finished work holds up rather than failing again from the same underlying cause. Trial areas are also worth agreeing upfront, particularly on commercial and insurance-related sites, since they let everyone confirm the finished texture and appearance before the full area is treated, reducing the risk of disputes once reinstatement is under way.
