Corrosion analysis

ACUO SI Ltd provides specialist corrosion analysis in concrete to help engineers, contractors and asset owners assess the condition of reinforced concrete structures and identify the risk of reinforcement corrosion before significant damage occurs. Corrosion of embedded steel is one of the leading causes of deterioration in reinforced concrete and can result in cracking, delamination, concrete spalling, loss of bond and long-term structural damage if left untreated.

Our concrete corrosion testing services are designed to identify areas where embedded reinforcement may be at risk from moisture ingress, carbonation, chloride contamination and aggressive environmental exposure. These services are particularly valuable for car parks, bridge decks, balconies, retaining walls, marine structures, commercial buildings, infrastructure assets and ageing reinforced concrete structures undergoing inspection, refurbishment or structural appraisal.

Using industry-recognised half-cell potential testing, ACUO SI Ltd measures electrical potential across the concrete surface to assess the probability of active corrosion affecting embedded reinforcement. This allows us to identify and map areas of elevated corrosion risk, providing project teams with valuable data to support concrete repair strategies, structural investigation, maintenance planning and durability assessments.

Concrete corrosion analysis is especially important where there are signs of deterioration such as rust staining, cracking, dampness, delamination or spalled concrete, but it is also highly effective as a proactive diagnostic tool where long-term asset performance and service life need to be assessed. Early identification of corrosion-prone areas allows targeted repairs to be planned before more extensive structural damage develops.

All surveys are supported by clear technical interpretation and detailed engineer-ready reports, including testing methodology, survey findings, corrosion risk assessment and practical recommendations. ACUO SI Ltd delivers reliable, professional corrosion testing and concrete condition assessment services across London, the South East and throughout the UK, helping clients make informed decisions on repair, remediation and long-term asset protection.
