Concrete Repair

Concrete damage due to steel corrosion is a worldwide problem. The visible symptoms of concrete decay include cracking, spalling, rusting of exposed steel reinforcement and the staining of concrete surfaces.

During the corrosion process steel expands causing cracking or spalling of the cover concrete. Left untreated, deterioration will accelerate, seriously compromising structural integrity. Independent cover, chloride and carbonation testing will give an accurate diagnosis of the problem enabling specification of the most appropriate treatment. Anchor offers comprehensive solutions utilising products from all the major manufacturers ranges, and also specialise in resin injection, brickwork repair and the application of protective coatings.


Firestopping maintains the building compartmentation in a fire situation, impeding the spread of flame and smoke by filling openings with heat resistant materials to provide fire ratings ranging from 30 to 240 minutes.

Where services penetrate a fire compartment wall or floor the specified level of performance can be achieved with the use of a variety of firestopping systems. Anchor offer specialist firestopping solutions utilising the most appropriate products from the ranges of all the leading material manufacturers.
