TOPBOND PLC

With nearly 40 years' experience, Topbond plc is recognised as specialists in the field of concrete inspection and repairs with a particular emphasis on bridges and structures, having worked on numerous structures throughout the UK and overseas. Project values range from less than £1000 to over £4 million and all projects are undertaken in accordance with ISO 9001, 14001 and OHSAS 18001 procedures. Topbond is the proud holder of the prestigious Platinum Award in recognition of our commitment to the Construction Skills Certification Scheme (CSCS), with our skilled staff all carrying relevant CSCS cards as well as a range of other competences to suit various environments including confined spaces, railway and marine environments. Topbond's testing division HTS is UKAS accredited for a range of frequently requested concrete testing services which are supported by laboratory testing for concrete strength, chloride content, petrographic examination etc, allowing us to gain an understanding of the cause of reinforced concrete deterioration. HTS has extensive experience of undertaking Post Tensioned Special Inspections (PTSI or SPTI to BA 50/93) in the UK and Ireland. Modern investigation techniques such as video endoscope, ground probing radar, ferroscan or covermeter surveys can provide information on reinforcement arrangements and structural details. Access can be undertaken by abseiling, or by staff who are trained to operate MEWP (IPAF) and erect aluminium scaffolding towers (PASMA). Additional training for working in confined spaces and PTS training for working in the rail environment ensure HTS can survey in most environments. Concrete repair services include hydro-demolition, cast and sprayed concrete, carbon fibre strengthening. Cathodic Protection systems, including corrosion inhibitor and sacrificial anode technology, have been applied to bridges, carparks and jetties. As founder members of the Concrete Bridge Development Group, Topbond's work on Queen's Park bridge Rochdale was the subject of a technical paper (Clapham, Simpson and Ashley, CBDG Technical Paper No 11, 2005).
