Corrosion Risk Testing

Corrosion Risk Testing

Corrosion risk within reinforced concrete

Since its inception in the 19th century, reinforced concrete has been commonly used in many aspects of building construction. The inclusion of reinforcement within concrete significantly improves its tensile strength, allowing greater flexibility in its use.

This reinforcement is usually in the form of steel bars.  Concrete is naturally alkaline in nature and when concrete of suitable quality and of sufficient depth from the atmosphere is present, this alkalinity can be expected to provide protection to steel reinforcement.

Nicholls Colton undertakes a range of intrusive and non-intrusive inspection and testing works which can identify at an early stage the likelihood and subsequent confirmation of corrosion being present in reinforced concrete.  Nicholls Colton is UKAS* accredited for many of the tests required including:
