Concrete cancer is a serious problem that, if left undiagnosed and untreated, can have a detrimental effect on the structural integrity of a building. The best repair option depends on the materials of construction and the specific cancer repair job. It is important to consult a qualified engineer to perform a diagnostic analysis and identify the cause of the problem. The engineer can then describe what needs to be repaired.
If chloride pollution is the issue in buildings near the ocean, specialized repair work may be necessary to treat concrete cancer. Flat concrete roofs are particularly vulnerable to leaks and water-driven concrete cancer if not properly waterproofed. Once the underlying steel and concrete have been repaired, they must be cured properly with specialized coatings. For situations where concrete carbonation and low concrete coverage are the problem, a polymer-modified repair system may be recommended.
It is essential to repair and rectify all areas of specific cancer as detailed in the “Site-Specific Scope of Work (SSW)” that is compiled after a site visit. When steel expands, it creates more concrete cracks that allow for greater water penetration, the spread of cancer, and eventually chipping (when concrete starts to fall off a building), which will continue if left untreated. Concrete pieces could begin to fall out of the structure, damage property and even endanger human life. It is important to watch for telltale signs that your building may be affected by concrete cancer. Retiring is a costly exercise rather than a long-term treatment of the building's concrete structure.
Therefore, it is essential to consult a professional and get advice on the type of repair work that needs to be done.
