Concrete Repair Services for Complex Structures in Durban and KZN

Concrete Spalling Repair

Structural Concrete Repair
Structural concrete repair to load-bearing elements including columns, beams, suspended slabs and pillar cracking. We diagnose the cause before we repair, so the work addresses corrosion and movement rather than covering them over.

Industrial Waterproofing

Protective and Anti-Carbonation Coatings

Concrete Crack Repair and Joint Sealing

Preventative Maintenance

Commercial Painting
We provide professional commercial painting services in Durban and KZN, delivering durable, high-quality finishes that protect and enhance commercial, industrial, and residential properties.
Professional Assessment is Non-Negotiable
Structural Weakening
Exposed steel reinforcement corrodes rapidly, leading to irreversible loss of critical load-bearing capacity and potential failure.
Cost Escalation
Early-stage repair costs a fraction of full structural rehabilitation or demolition, and it keeps the building in use while the work is carried out.
Our Concrete Repair Process
01. Technical Inspection and Concrete Survey
Visual survey, delamination sounding, cover meter readings and chloride depth analysis to establish the root cause and the true extent of the damage before anything is priced.
02. Concrete Repair and Reinforcement Treatment
Mechanical removal of delaminated concrete, cleaning and treating the exposed steel, then reinstating the section with a specified repair mortar.
03. Protective Coating and Waterproofing
High-performance sealing and anti-carbonation coatings for multi-decade durability.
Concrete Defects We Repair
Most enquiries start with a symptom rather than a diagnosis. If you can see any of the following on a commercial, industrial or body corporate building in KZN, it is worth booking a site assessment.
Cracked Walls, Columns and Slabs
Concrete crack repair to wall, slab, column and pillar cracking. We establish whether the crack is structural, shrinkage related or the first sign of reinforcement corrosion, then repair by resin injection or by breaking out and reinstating the section.
Flaking, Pitting and Crumbling Surfaces
Flaking and pitting concrete is usually early spalling. Concrete flaking repair and concrete pitting repair at this stage costs far less than waiting for the reinforcement to expose itself.
Cracked Ceilings and Soffits
Concrete ceiling crack repair to parking decks, walkways and apartment soffits. Overhead damage is the most common presentation of spalling in Durban apartment blocks and the most dangerous to leave.
Failed Expansion and Construction Joints
Concrete expansion joint repair and resealing to decks, parapets, warehouse floors and precast panels, where a failed sealant is letting water reach the reinforcement behind it.
Rust Staining and Exposed Steel
Rust staining and exposed reinforcement mean the corrosion cycle is already running. This is structural concrete repair, not a patching job.
Water Tracking Through Slabs and Decks
Concrete slab crack repair and slab leak investigation where water is finding a path through a deck into the space below.

Concrete Repair and Spalling FAQs
How does the repair process work?
We start with a site assessment to establish the cause and the extent of the damage. From there we scope the work, price it and agree a programme with you. The same team runs the project from assessment through to handover, so you are not passed between people.
How long will my project take?
Every project differs, but you get a clear programme after the site assessment and updates as the work progresses. Access, weather and the extent of hidden damage are the three things that most often move a concrete repair timeline, and we flag them at the start rather than at the end.
How do I know if my building has spalling?
Common signs include cracking, bulging, rust stains, or pieces of concrete falling away from surfaces such as balconies, columns, or ceilings. If you notice any of these, a professional inspection is recommended.
Why should I choose a specialist contractor?
Concrete repair and spalling treatment require specific expertise, materials, and techniques. Using a specialist ensures the root cause is addressed and that repairs are durable and compliant with industry standards.
Do you offer site inspections and quotes?
Yes, we offer professional site assessments to evaluate the condition of your structure and provide detailed, transparent quotations based on the required scope of work.
Why is concrete spalling common in Durban and coastal areas?
Concrete spalling is more common in Durban due to high humidity and salt-laden air, which accelerate corrosion of steel reinforcement within concrete structures. This leads to cracking, expansion, and eventual surface failure.
How long does concrete spalling repair last?
When completed by experienced specialists using high-quality materials, concrete spalling repairs can last for many years. Proper preparation, corrosion protection, and waterproofing are key to long-term durability.
How much does concrete repair cost in Durban, South Africa?
Concrete repair cost depends on the extent of the damage, access, and the repair system specified. Overhead and rope access work costs more than repair at ground level, and a small area of spalling caught early costs a fraction of a full elevation. We quote per project after a site assessment, and the quote sets out the scope so you can compare it fairly against other contractors.
What is concrete spalling and how is it repaired?
Concrete spalling is the cracking, flaking, or breaking away of concrete caused by corrosion of internal steel reinforcement. Repair involves removing damaged concrete, treating the corroded steel, and reinstating the area with specialized repair materials to restore structural integrity.
Can spalling concrete be repaired, or does it need to be replaced?
In most cases it can be repaired. Spalling is a reinforcement corrosion problem, so provided enough sound concrete and steel section remains, we break out the damaged area, treat or replace the steel and reinstate it. Replacing an element is only necessary where section loss is severe, and that is a decision we make with an engineer rather than on our own.
How do I know if I need structural concrete repair rather than a cosmetic patch?
Cracking that moves or reopens, rust staining, hollow sounding concrete, exposed reinforcement, or damage to columns, beams and suspended slabs all point to structural concrete repair. Our inspection includes delamination sounding and cover readings, so you get a clear answer rather than a guess.
Do you work with body corporates and managing agents?
Yes. A significant share of our work is body corporate and managing agent contracts on coastal apartment blocks, where balcony and soffit spalling is the most common defect. We can provide a scoped condition report suitable for a trustee meeting or an AGM.
Can you carry out concrete repairs on an occupied building?
Yes. Most of our repair work happens on buildings that stay in use. We phase access, protect the areas below overhead work, and agree working hours with you in advance so the disruption is planned rather than discovered.
Who We Work With
Body corporates and managing agents dealing with spalling balconies, soffits and walkways. Facility and property managers responsible for the condition of commercial buildings. Industrial and warehouse operators with slab, joint and structural repair requirements. Engineers and consultants who need a concrete repair contractor that will follow a specification rather than improvise on site. If you need a scoped condition report for a trustee meeting, an AGM or a maintenance budget, we can provide one.
