Understanding the design, material characteristics and deterioration processes affecting a particular reinforced concrete building or structure is essential in diagnosing the causation and extent of defects affecting a structure.

This enables a durable and cost-effective concrete repair to be instigated. We provide in-depth reports detailing our findings gathered from using Our Rope Access Inspection Team from High Rise Buildings to Multi Storey Car Parks.

Undertaking a sufficient and appropriate concrete survey is a requirement of BS EN 1504, Products and systems for the protection and repair of concrete structures.

Some of the testing and survey techniques we can employ in the assessment of existing concrete structures include:

  • Rope Access Defect Surveys which can be used to provide a Bill of quantities for repair in accordance with the CRA Standard Method of Measurement
  • Delamination Survey to assess sub-surface cracking due to reinforcement corrosion
  • Covermeter survey to assess concrete cover to reinforcement
  • Carbonation testing to assess concrete alkalinity.
  • Concrete sampling to determine presence of cast-in chlorides, chloride contamination and to determine chloride profile
  • Concrete core sampling for inspection purposes or for compressive strength determination or petrographic examination
  • Half-cell potential surveys
  • Pull Out Resistivity measurement
  • Corrosion assessments and prevention.
  • Use of Ferroscan and Proceq survey instruments to determine reinforcement provision or large-scale assessment of concrete cover to reinforcement
  • Break Outs to determine aggregate and reinforcement type

We have extensive knowledge of investigating, testing and surveying a wide range of reinforced concrete structures and buildings, including bridges, culverts and tunnels, coastal defences, historic buildings, multi-storey car parks, high-rise buildings, undercrofts and swimming pools, industrial facilities.

Our Specialist Rope Access Team or Confined Space Entry Team have the knowledge and expertise to carry out any of the disciplines, tailored to meet your requirements.
