Good concrete should have excellent durability in a variety of environments. However, unresolved problems are associated with its use,including design and detailing, mismatch of materials used in construction and repair, workmanship and abnormally aggressive environments.

The serviceability of a concrete structure may be reduced over time by the disintegrating effects of in-service conditions such as weathering, and mechanical or chemical action involving cyclical load, wear, abrasion and chemical attack. These problems can cause significant deterioration in generation plant structures.

Methods to address to these issues may involve in-site assessment of the structures using both destructive and non-destructive equipment. Concrete coring is the most effective method of defining the extent of damage to the concrete structure and in some cases, the underlying foundations.

Active Concrete has the expertise, experience and state-of-the art facilities to properly assess and carry out reliable, effective concrete repair and rehabilitation.


Concrete coring may be required in order to run electrical, plumbing, cabling or other services to a specific area if it cannot be done via another  route. Concrete cutting may be required for the same reasons or in order to make structural changes.
