Carbon Fibre Wrapping is an innovative solution for structural strengthening.

Carbon fibre has very high tensile strength and is also very lightweight. When bonded to the exterior of a concrete column, beam, or slab, it can add significant strength without adding weight that would increase the load on foundations and other structural members.

A mix of usually carbon or glass fibre fabrics, and an epoxy resin, wrapping systems are custom designed for each project and application.

Carbon Fibre Wrapping provides significant strength to structures and protects against further corrosion and erosion. The impervious material will protect a structure from moisture intrusion and further corrosion, reducing the need for ongoing maintenance work.

Installation

Successful installation of Carbon Fibre Wrapping requires experience and skill. As with all refurbishment work, the first step is correct surface preparation to remove any chemicals or dirt.  Following surface preparation and removal of dust, any defects in the concrete are repaired. Sharp edges and corners are smoothed to prevent stress concentrations. The concrete is then coated with a primer to allow for a mechanical bond before the Carbon Fibre Wrapping is fitted. The fabric can be placed in up to three layers, depending upon design. A topcoat will then be installed to provide temperature, chemical and abrasion resistance.

Carbon Fibre Wrapping isn’t suitable for every strengthening project and you should always get advice from a specialist contractor about the best method to use.

The use of carbon fibre plates and rods are also available for structural strengthening.

CSC Services provide refurbishment services and protective coatings to structures across the UK water sector, in nuclear power stations, public sector buildings such as hospitals and prison buildings, and across UK infrastructure including bridges, tunnels, culverts and sewers.

Latest Projects

Carbon Fibre Wrapping was completed as part of the 2017 Spalling Concrete Remediation Programme at Hinkley Point B Power Station for client EDF Energy.  The innovative solution was used for structural strengthening to the DW Plinths in the Turbine Hall.

For years the DW plinths had simply been painted and as a result had fallen into a state of significant disrepair, putting their structural integrity at risk. Supporting heavy and expensive plant equipment, it was important that the correct course of remedial action was taken. Carbon Fibre Wrapping will not only provide significant strength to the plinths, it will protect against further corrosion and erosion. The impervious material will protect the structure from moisture intrusion and further corrosion, reducing the need for ongoing maintenance work for the life of the station or structure.
