CFRP Slab Strengthening — Concrete Slab Strengthening with CFRP

About the Service

What is CFRP Slab Strengthening?
And How Does It Work?

CFRP Slab Strengthening is a technique of bonding Carbon Fibre Reinforced Polymer (CFRP) to the soffit of concrete slabs to increase flexural and shear capacity, reduce deflection, and extend structural service life — without demolishing the slab or disrupting building occupancy.

CFRP bonded to the slab soffit significantly increases flexural and shear strength, reduces deflection, and prevents cracking. Ideal for building floors, car parks, bridges, factories, and high-load areas.

Suitable for:

Commercial & Residential Building Floors Car Parks & Parking Decks Bridges & Civil Structures Factory & Warehouse Floors High-Load Areas

Key Features

Capabilities of CFRP Slab Strengthening

International-grade structural carbon fibre that increases slab flexural and shear capacity, reduces deflection, and prevents cracking — without demolishing the slab or disrupting building use.

Increased Flexural Strength

CFRP bonded to the slab soffit increases flexural capacity by more than 2×, accommodating increased loads from building extensions or changes in occupancy.

Increased Shear Strength

CFRP applied diagonally or vertically at supports increases shear capacity, preventing shear failure caused by heavy loads or seismic forces.

Deflection Control

Increasing slab stiffness reduces excessive deflection to within acceptable limits, preventing damage to walls, ceilings, and building services below the slab.

No Slab Demolition or Downtime Required

Works are carried out at the slab soffit with no need to remove floor finishes, tiles, or services, significantly reducing downtime and overall project costs.

International-Standard CFRP Materials

Certified structural-grade carbon fibre — lightweight, high-modulus, corrosion-resistant, and built for long-term performance in all environments.

Specialist Structural Engineering Team

Designed by specialist structural engineers who calculate CFRP layers to load requirements and ACI/FIB standards, with quality guaranteed on every project.

Our Process

The CFRP Slab Strengthening Process

A systematic process by specialist structural engineers — from slab survey and analysis, surface preparation, and CFRP application, through to testing and quality certification to international standards.

Slab Survey & Analysis

Inspect slab and structural condition, test concrete strength, analyse acting flexural and shear forces, and design the CFRP strengthening system to ACI/FIB standards.

Slab Soffit Surface Preparation

Grind and prepare the concrete soffit to a clean, level finish to standard, repair cracks and damaged areas, and apply primer to improve CFRP bond.

CFRP Application & Lamination

Apply CFRP to the slab soffit in the calculated flexural direction and number of layers, coat epoxy resin between layers for bonding and load transfer, and inspect adhesion uniformity on every layer.

Testing & Quality Certification

Verify bond strength with Pull-off Test, inspect CFRP layer uniformity, and issue a quality report certifying the strengthening works to ACI/FIB standards.

Applications

What Types of Projects Is It Suited For?

CFRP Slab Strengthening is ideal for slabs requiring structural strengthening, increased load capacity, or damage repair — without demolishing the slab or disrupting building use.

Commercial & Residential Building Floors — Strengthen slabs in buildings requiring increased live loads, additional floors, or a change of use — without demolishing the slab or rebuilding.

Car Parks & High-Load Areas — Strengthen deteriorated parking decks or slabs requiring capacity for heavier vehicles, without closing the facility.

Bridges & Civil Structures — Strengthen bridge deck slabs carrying increased traffic loads, or upgrade to meet updated structural standards.

Factory & Warehouse Floors — Strengthen floors in factories requiring additional machinery or material loads, without halting production.

Ageing & Deteriorated Slabs — Repair and strengthen cracked, deflecting, or deteriorated slabs, restoring their full load-bearing capacity.
