Repair
Concrete Repair
Diagnosis and repair of deteriorated concrete to restore strength, durability and service life (EN 1504).

Concrete repair is the diagnosis and reinstatement of structures that have deteriorated through cracking, spalling, corrosion of reinforcement, water damage, or impact. The goal is not cosmetic patching but the durable restoration of structural integrity and service life.
Power Builders works to the EN 1504 framework — the European standard for the protection and repair of concrete. We identify the root cause, prepare the substrate back to sound concrete, treat exposed reinforcement, and reinstate the section with engineered repair mortars and resins selected for the exposure and load.
This service sits within our Specialized Contracting sector and draws on the same expertise as our restoration programmes, including major works delivered with Hassan Allam Construction and CCC such as the Cairo Festival City expansion.
Why You Need It
Concrete deterioration is rarely just a surface problem. Once water and chlorides reach the reinforcement, corrosion expands the steel, cracks the cover, and accelerates failure — a process that only worsens if the cause is left unaddressed.
Proper repair stops that cycle. By treating the cause, protecting the reinforcement, and reinstating the section correctly, repair restores capacity and extends the life of the asset at a fraction of the cost of replacement — while keeping the structure in service.

-
Survey & Diagnosis
We assess the structure, identify the cause and extent of the damage, and confirm the repair specification with the design team.
-
Breakout & Preparation
Damaged concrete is removed back to sound substrate, and exposed reinforcement is cleaned, treated, or supplemented as required.
-
Reinstatement
The section is rebuilt with engineered repair mortars or resins selected for the exposure, load, and EN 1504 repair principle being applied.
-
Protection & Verification
Repairs are cured, finished, and where needed sealed against future ingress, then checked against the specification before handover.

Frequently Asked Questions
The most common causes are corrosion of the reinforcement (driven by carbonation or chlorides), cracking, water ingress, and impact or overload. Effective repair starts by identifying which of these is at work.
We address the root cause. Patching over corroding steel or an active crack only hides the problem; lasting repair treats the reinforcement and the source of damage before reinstating the section.
We follow the EN 1504 framework, the recognised European standard for concrete protection and repair, using EN 1504-3 mortars for section reinstatement.
In most cases, yes. Repairs are typically carried out in zones with minimal disruption, which is one of the main advantages over demolition and replacement.
Depending on whether the crack is structural or a water path, we use epoxy or polyurethane resin injection to restore monolithic behaviour or seal against leakage.
