Descaling concrete that is not attended to in a timely manner will only lead to additional repair costs as the problem grows and spreads. In my opinion, the issue is not caused by the contractor's coloring methods, but rather due to poor installation techniques, inadequate curing, or improper concrete mixing - or a combination of all three. Stamping the surface of bad concrete only accelerates the deterioration process. What makes matters worse is that the contractor refuses to take any responsibility and won't get involved to help figure out what happened.
Concrete Peeling affects a wide variety of structures, including concrete frame buildings, multi-storey car parks, bridges, jetties, tanks and ponds. Chipping can have far-reaching consequences in terms of health and safety, structural integrity and asset value. Unfortunately, an adhesive plaster approach is often taken to repair peeling structures, without treating the underlying causes. So, what exactly is chipping? What are its effects and how can structures be successfully repaired and further corrosion prevented? Unlike your car, which you can rinse off, it is more difficult to remove the spray from all areas of your building. This means that over time, those forces of nature that hit the salt water in your building will cause small amounts of erosion and damage.
Repeated blows by wind, dew, light rain and the like mean that salt that settles on concrete has a high probability of reacting with chemicals inside concrete and those in steel itself, leading to rust. Over time, this rust will cause flaking of concrete. Splinters can appear because the rebar has been exposed and moisture and water have started to rust the rebar or because the concrete joints were built incorrectly. Engineers believe that porous building materials can be protected against salt peeling by treating them with penetrating sealants that are hydrophobic (water repellent) and penetrate deep enough to keep water with dissolved salts away from the surface.
Concrete Peeling, commonly known as 'concrete cancer', is a pain in the eye and has the potential to be an extreme danger.
Descaling concrete can have far-reaching consequences in terms of health and safety, structural integrity and asset value. On the other hand, it doesn't necessarily mean that the base is flaking just because water may be present in a basement. If left untreated, the damage caused by the peeling of concrete can grow exponentially, as more and more water or moisture can enter the structure due to existing cracks and open cavities caused by the flaking of concrete. Concrete flaking occurs when carbonation and high levels of chloride in the environment (usually present in coastal areas) cause corrosion of buildings. Concrete peeling is usually caused by corrosion of steel reinforcing bars embedded in the concrete matrix, but can be caused by other ferrous elements, either totally or partially embedded in the structure. That said, although it can last for decades, concrete doesn't usually last without at least a modest amount of care and maintenance.
Peeling of concrete can also occur when the ends of the reinforcing beams are too close to the surface. When reinforcing steel rusts, it expands to 700% of its original size, causing the surrounding concrete to shift.
