What is Concrete Cancer
The problem is that concrete can be affected by loss of protective alkalinity due to reaction with atmospheric carbon dioxide.
Where this occurs chemical changes can take place in the concrete, which reduces its strength.
Worse still, steel reinforcing within the concrete can rust and the pressure this creates can cause the concrete to crack and crumble.
Buildings in coastal areas are especially at risk. The most frightening thing is that the corrosion can be going on under the surface and will not be noticed until the concrete starts visibly disintegrating.
Repairing Concrete Cancer
All loose and affected concrete is removed and all rusted steel is treated and taken back to new condition. The concrete is replaced with either hi build mortar repairs or epoxy repair systems depending on the location and type of damage is found.
When it comes to concrete cancer, there’s no one-size-fits-all solution.
The best repair option depends on your building materials and the extent of damage.
Regardless of whether the damage is severe or moderate, waterproofing and comprehensive sealing after the repair is important to minimise the risk of concrete cancer in the building.
