Repairs & Rehabilitation

Proven repair techniques and rehabilitation systems to restore structural capacity, extend service life, and protect against future deterioration.

Restoring Structural Integrity

Struct Rehab executes structural repair and rehabilitation works across the full spectrum of techniques, from simple crack repair to complex external post-tensioning systems on major bridge structures. Our on-site teams are experienced in executing works on live structures, under traffic, and in challenging environments including marine and submerged conditions.

We specify and source only proven, tested repair materials and systems, and maintain quality assurance records through every phase of the works.

Structure Types We Work On

  • Road and rail bridges (RCC, PSC, steel composite)
  • Flyovers and grade separators
  • Jetties, wharfs, and marine structures
  • Industrial structures and chimneys
  • Retaining walls and substructures
  • Post-disaster structures requiring emergency repair

Repair & Rehabilitation Services

External Prestressing

Application of external post-tensioning tendons to restore or enhance the flexural and shear capacity of deteriorated or under-strength bridge decks and beams.

  • Detailed tendon layout and anchorage design
  • Strand and bar systems for various spans
  • Deviator block construction and installation
  • Stressing, monitoring, and grouting operations

Structural Jacketing

Reinforced concrete jacketing and fibre-reinforced polymer (FRP / CFRP) wrapping systems to increase the strength and ductility of columns, beams, and piers.

  • RCC jacketing for columns and pier shafts
  • Carbon fibre (CFRP) and glass fibre (GFRP) wrapping
  • Confinement jacketing for seismic retrofitting
  • Beam soffit and web strengthening

Epoxy Injection & Grouting

Pressure injection of epoxy resins and cementitious grouts to seal cracks, fill voids, and restore structural monolithism in concrete members.

  • Low-viscosity epoxy crack injection
  • Cementitious and micro-fine grouting
  • Tendon duct re-grouting
  • Void filling in box girder sections

Bearing Replacement

Replacement of failed or deteriorated bridge bearings with modern elastomeric, POT-PTFE, or spherical bearing systems, including temporary jacking and substructure repair.

  • Elastomeric and POT-PTFE bearings
  • Temporary jacking and shoring design
  • Bearing shelf and seating repairs
  • Installation and alignment verification

Underwater Repairs

Specialist repair and protection of below-waterline structural elements including bridge piers, pile caps, jetty piles, and sea walls.

  • Underwater concrete repairs and jacketing
  • Impressed current cathodic protection (ICCP)
  • Sacrificial anode systems
  • Marine epoxy coatings and protective wraps

Polymer Modified Mortars & Coatings

Application of polymer-modified repair mortars, anti-carbonation coatings, and protective systems to restore surface profiles and prevent future deterioration.

  • Spalled and delaminated concrete reinstatement
  • Structural repair mortar application
  • Anti-carbonation and waterproof coatings
  • Chloride barrier and corrosion inhibitor treatments
