Concrete investigations: Bridge Assessment / Condition Surveys

The first signs of cracking and rust staining can serve as an early warning that deterioration of a reinforced concrete structure is about to take hold. However, these signs are not always in evidence requiring specialist knowledge coupled with appropriate technology to identify if the structure is suffering deterioration, albeit in the early stages. Stanger's have developed the expertise necessary to carry out investigations of concrete structures over many years, both in the UK and overseas, and can therefore offer their clients a multi-disciplined based services, tailored to meet their requirement.
