Structural Strengthening
Increasing the load capacity of existing structures using section enlargement, steel and composite systems.

Structural strengthening upgrades the capacity of existing concrete and masonry elements so they can safely carry greater loads, or recover capacity lost to age, corrosion, or damage. Rather than demolishing and rebuilding, the existing structure is reinforced in place.
Power Builders applies carbon-fibre reinforced polymer (CFRP) systems — fabric wraps and pultruded laminates bonded to beams, columns, and slabs — alongside steel plate bonding and supplementary rebar where appropriate. CFRP is exceptionally strong, corrosion-proof, and thin, so it adds capacity with almost no change to member size or weight.
This service sits within our Specialized Contracting sector. It is the discipline behind landmark restoration work such as the strengthening of the CIB Bank headquarters, delivered with Hassan Allam Construction.
Why You Need It
Buildings and infrastructure are often asked to do more than they were originally designed for — heavier equipment, new floors, changed use, or simply the effects of time and corrosion on the original reinforcement.
Strengthening restores and increases capacity at a fraction of the cost, disruption, and downtime of demolition and reconstruction. It extends the service life of the asset, keeps it in use during the works, and is frequently the only practical option for structures that cannot be taken offline.

-
Structural Assessment
We review the structure, loads, and condition with the design team to confirm the required capacity and the right strengthening system.
-
Surface Preparation
Substrates are cleaned, repaired, and profiled so the strengthening system bonds correctly to sound concrete.
-
System Application
CFRP wraps or laminates, steel plates, or supplementary rebar are installed and bonded under controlled conditions by trained crews.
-
Curing & Quality Assurance
The system is cured and checked, with bond and installation verified before the element is returned to service.
Techniques & Equipment
- Carbon Fibre (CFRP) Wraps Confinement and shear strengthening of columns and beams
- CFRP Laminates / Plates Flexural strengthening of beams and slabs
- Steel Plate Bonding Added capacity where steel is specified
- Supplementary Rebar Reinforcement reinstatement and section enlargement
- Chemical Anchoring Connecting new reinforcement to the existing structure

Frequently Asked Questions
In most cases, significantly. It avoids demolition, reconstruction, and the downtime of taking the structure out of service, while delivering the required capacity.
Usually yes. CFRP and bonded systems are applied in place with minimal disruption, which is often the main reason strengthening is chosen over reconstruction.
It depends on the element and the engineering design. CFRP is used for both flexural and shear strengthening and is specified by the structural designer to meet the target loads.
Carbon fibre does not corrode, which is a key advantage over traditional steel solutions in aggressive or humid environments.
