Concrete Remediation — Cake Commercial Services

Concrete Remediation

Concrete deteriorates long before it fails, and most of it can be repaired rather than replaced. CAKE delivers concrete repair, injection, structural strengthening and protective treatment to commercial, industrial and infrastructure assets throughout New Zealand.

Our Services

What we offer

Concrete repair to warehouse and industrial floors, building structures and infrastructure assets

Structural strengthening with carbon fibre and fibreglass systems to beams, columns, slabs and walls

Polyurethane and epoxy injection to structural and non-structural cracks, and water-stop injection

Core cutting, penetration coring and concrete sawing

Protective and anti-carbonation coatings applied to remediated concrete

Our concrete repair work spans warehouse and industrial floors, building structures including beams, columns, walls and slabs, and infrastructure assets such as bridges and reservoirs, along with grinding and sealant work.

We also apply protective and anti-carbonation coatings to remediated concrete, so the repair is protected against the conditions that caused the damage in the first place.

Why concrete deteriorates

Concrete itself is durable. The problem is usually the steel reinforcement inside it.

Concrete protects reinforcement by keeping it in a highly alkaline environment. Over time, carbon dioxide from the air lowers that alkalinity in a process called carbonation, and in coastal or industrial environments chlorides penetrate the surface. Once either reaches the reinforcement, the steel begins to corrode. Corroding steel expands, and that expansion cracks and spalls the concrete around it, which lets in more water and accelerates the process.

That is why cracking and spalling are symptoms rather than the problem. A repair that patches the surface without addressing the cause will fail again. We assess what is driving the deterioration before specifying a repair, and where appropriate we protect the finished surface so the cycle does not restart.

Water ingress is the other common issue, particularly in basements, retaining walls and below-ground structures. Injection systems can seal an active leak from within the structure without excavation.

How we work

Concrete remediation is often carried out on assets that stay in use, including car parks, operating warehouses and occupied buildings. We plan the work around that, staging access and containment so the asset keeps functioning.

Our project management team has delivered remediation on major roading network projects for Alliance partners, and we bring the same quality assurance approach we use across our coatings work. Repairs are recorded, materials and methods are documented, and clients can see progress during the project rather than at the end.

Our systems are ISO 9001, ISO 14001 and ISO 45001 certified.

Where we work

We deliver concrete remediation nationwide from bases in Auckland, Wellington and Christchurch, including throughout the South Island and its regional centres.

We take on work at any scale, from a single car park deck or a cracked retaining wall through to full structural remediation programmes.

Frequently asked questions

In most cases yes, and it is usually far cheaper and less disruptive than replacement. Repair is viable as long as the structure retains adequate capacity and the cause of the deterioration can be addressed. An assessment will establish which applies.

Carbon fibre and fibreglass systems are bonded to concrete elements to increase their load capacity. They are commonly used where a structure needs to carry more than it was designed for, such as a change of building use or new plant, or where reinforcement has been lost to corrosion. The systems are thin and add very little weight or depth.

Yes. Water-stop and polyurethane injection systems are installed from within the structure and react with water to seal the path the leak is following. This avoids excavating to reach the outside face of a wall.

Some cracking is cosmetic and some indicates a structural issue or active reinforcement corrosion. Width, pattern, location and whether the crack is moving all matter. We can inspect and advise, and involve a structural engineer where the assessment calls for it.
