Concrete and Brick Repairs

Cemplas concrete repairs extend the life of buildings and car parks. Surveyors identify the cause of decay with hammer testing, visual survey, carbonation test, and chloride test and cover meter test (this records the depth of steel reinforcement below concrete and provides a “low cover”
warning).

Typical concrete problems are caused by low cover to the reinforcement, carbonation of the concrete and/or high chloride levels.
Cemplas solutions include the reinstatement of defective concrete and the application protective Anti-Carbonation coatings which slows the loss of alkalinity to the concrete. Some coatings can regenerate the concrete and stop decay. Knowledge is important to concrete repairs and Cemplas can make recommendations that reduce costs. An accurate survey will establish the true cost of repairs at the outset thus avoiding the possibility of cost implications during the contract period. Cemplas also provides remedial treatment for new buildings. These relate to problems usually caused by a building mistake during construction.

Brick repairs
Most brickwork will settle and cause cracking. These are usually localised problems and in those circumstances, Cemplas recommend resin injection as a more cost effective durable repair compared to removing and rebuilding the cracked area.

Resin injection
Cracks are caused by movement, or lack of cover in concrete. Cemplas uses epoxy resin to stabilise and strengthen the crack. This was used extensively at a major refurbishment for the Government Offices, Great George Street.
