Durability Assessments and Concrete Condition Surveys

Birmingham City Laboratories has gained extensive knowledge investigating and surveying a wide range of structures; these include bridges, tunnels, coastal defences, historic buildings, multi-storey car parks, high rise buildings, system built dwellings, swimming pools, industrial facilities and office buildings.

Understanding the design, material characteristics and deterioration processes affecting a particular building or structure is essential in diagnosing the causation and extent of defects affecting that structure. This enables a durable and cost effective repair to be instigated and decisions made with regard to life-costing.

At BCL we provide in depth reports detailing our findings and also provide advice on the most appropriate repair strategies and systems.

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

Detailed below are some of our key services:-

Investigation of deterioration related to reinforcement corrosion

  • visual inspection and defect survey
  • delamination survey [tapping survey]
  • cover meter survey
  • carbonation depth
  • chloride determinations and profiling
  • half-cell potential survey
  • resistivity survey
  • reinforcement condition and detail [inspection/ferroscan]
