The use of reinforced concrete elements within a structure continues to be one of the most common and economically viable methods of construction within Singapore’s diverse built environment.
However, like you would service your car, concrete too, requires maintenance to prolong its working life.
Increasing levels of pollution and Singapore’s salt and moisture rich coastal environment pose serious structural and safety issues for buildings due to the corrosive effects of such elements. When the steel reinforcement of a concrete structure comes into contact with moisture over an extended period of time it corrodes and expands. This can lead to concrete cracks and corrosion induced spalling, issues that may significantly compromise the strength of the overall structure.
Cracks and spalling within concrete needs to be repaired by experienced remedial tradespeople in order to guarantee the performance and value of an asset. As specialists in building repair, we combine the skills and expertise of our team with extensive knowledge of, and access to, materials from around the world to tailor-make solutions to suit every problem. By taking a long-term view, such solutions don’t simply address the problem in hand, but ensure the guaranteed performance of every repair.
Concrete Crack Repair
It is important that each situation is individually assessed and the correct repair technique is specified. We are fluent in a range of crack repair methods to meet the needs of wet and dry conditions along structural or non-structural requirements. We currently practice the below crack repair techniques;
- Polyurethane injection repair is used in the areas of waterproofing where flexibility is required and cracks are non-structural,
- Epoxy injection repair used for structural requirements in existing designs
Surface repairs (Fine crack repair)
- Pour in epoxy grouts,
- Cementitious / Epoxy trowel repairs,
- Polyurethane Caulking,
Subsurface repairs (In-depth cracking), the cause of subsurface cracking can be correlated to; design error, excessive loading and corrosion induced cracking.
