STRUCTURAL REPAIR & STRENGTHENING

Swantest delivers a complete structural repair and strengthening capability, supported by in‑house investigation, testing and engineering expertise. Our teams specialise in diagnosing deterioration, understanding structural behaviour and designing targeted interventions that restore capacity, extend service life, and ensure safe, compliant performance of existing assets.

CFRP Strengthening

Corrosion Control

Investigation, Testing & Structural Behaviour Assessment

Swantest begins every project with evidence‑based understanding. Through detailed condition surveys, material sampling, corrosion mapping, and structural testing, we identify the root causes of deterioration and quantify residual capacity.

Our engineers assess reinforcement corrosion, carbonation, chloride ingress, cracking patterns, and load‑path vulnerabilities to determine the most effective repair and strengthening strategy.

This investigative approach ensures that every intervention is technically justified, durable, and aligned with the asset’s operational requirements.

Corrosion Control & Durability Management

Corrosion is one of the most common and costly causes of structural degradation. Swantest provides a full suite of corrosion control services designed to halt deterioration and protect reinforced concrete for the long term.

Our capabilities include:

Corrosion surveys and half‑cell potential mapping
Chloride profiling and carbonation depth analysis
Identification of active vs. passive corrosion zones
Specification of cathodic protection or corrosion‑inhibiting systems
Durability modelling and service‑life extension strategies

By combining diagnostic testing with targeted corrosion mitigation, we help clients stabilise ageing structures and avoid unnecessary demolition or large‑scale reconstruction.

Concrete Repair & Structural Remediation

Swantest delivers high‑quality concrete repair solutions that address both the symptoms and the underlying causes of deterioration. Our teams are experienced in structural and non‑structural repair techniques, including:

Break‑out and reinstatement of defective concrete
Repair of spalled, delaminated, or chloride‑contaminated areas
Application of high‑performance mortars and repair compounds
Crack injection and resin‑based remediation
Protective coatings and surface treatments for long‑term durability

Every repair is designed to integrate seamlessly with the existing structure, restore load‑carrying capacity, and meet the relevant standards for durability and performance.

CFRP/FRP Strengthening for Structural Enhancement

Swantest provides advanced Fibre‑Reinforced Polymer (FRP) strengthening solutions for increasing the capacity of existing structural elements. Using carbon fibre (CFRP) and other composite systems, we deliver strengthening for:

Flexural enhancement of slabs and beams
Shear strengthening for beams and transfer elements
Axial and confinement strengthening for columns
Local strengthening around new penetrations, openings and alterations
Remediation of design or construction defects
Load increases due to change of use or new equipment

Our FRP solutions include plate bonding, wrap systems, column encasement, and hybrid strengthening that integrates steelwork or high‑performance concrete where required. Working with leading materials suppliers, we ensure that each system is specified, tested, and installed to meet stringent performance criteria.

Strengthening of Post‑Tensioned and Reinforced Concrete Structures

Swantest has extensive experience working with complex reinforced and post‑tensioned structures. We support structural alterations, penetrations, and remedial works while maintaining the integrity of existing tendons and reinforcement.

Our approach includes:

Condition assessment of PT tendons and anchorages
Safe formation of slab penetrations
Strengthening using CFRP and concrete enhancement systems
Remedial anchorage design where required
Punching shear strengthening for slabs and transfer zones

This capability allows clients to adapt and upgrade existing structures safely, even in highly constrained or operational environments.

Engineering, Methodology & Delivery Assurance

Every strengthening and repair project delivered by Swantest is underpinned by rigorous engineering and method development. We produce detailed construction methodologies, testing plans, and installation procedures to ensure safe, predictable, and auditable delivery.

Our teams provide:

Structural analysis and capacity verification
Strengthening design and detailing
Installation sequencing and temporary works coordination
Quality assurance, testing and verification
Full documentation for compliance and asset records

This integrated approach ensures that strengthening works are not only technically robust but also practical, buildable, and aligned with site constraints.
