Is it dangerous to flake?

Identify concrete chipping and cancer. More importantly, they can be a hazard to people and other property should large pieces of concrete break and fall from a building. The peeling of concrete not only damages the aesthetic appearance of the building, but also affects the performance and stability of the structure in the long term if no immediate remedy is applied. Concrete is a mixture of cement, aggregates and water that hardens over time, which is strong in compression (“push”) while weak in tension (“traction”).

This means that concrete falls apart relatively easily when pulled, at about 10% capacity under “thrust pressure”. This weakness in concrete is overcome by providing a reinforcing bar having good tensile strength in the structural concrete members to absorb the tensile force in the member. peeling concrete exposes the reinforcing bar underneath to atmospheric moisture, as well as direct contact with water on some other occasions. This promotes oxidation of the reinforcing bars when the diameter of the reinforcing bar and therefore its tensile capacity is reduced over time, to a point where said reinforcing bar is completely broken or damaged too much and is structurally unsuitable for the designated structural member.

In such a scenario, the failure of the structure is just a time bomb, which does not surprise an engineer. The ingress of water can cause more than leaks and flaking: it can lead to hazards associated with peeling. Concrete peeling is also known as concrete cancer. It has the ability to cause serious hazards, public injury and loss of public property, as it can damage the entire structure, such as damage to rebar inside concrete.

It is very important to address chipping problems when they start to occur. While chipping affects a variety of buildings, including homes, apartment complexes, and parking lots, many homeowners don't know what it is. Unfortunately, if you can't recognize the signs and when to call a flaking repair contractor, your structure could be at risk. Here's a guide on what it is, how to tell if it's a problem and how it can damage your property.

When moisture enters materials such as brick or concrete, it creates rust that forms on the rebar inside. The surface may begin to peel or flake as the first sign. If your property has a chipping problem, you will also notice loose pieces of concrete, pitting and rust stains. In general, the main areas to consider include concrete floors, building foundations and beams.

Once the oxidation starts, it's hard to stop it. Using a licensed contractor with proven methods to stop chipping is extremely important. Hawaii's climate is unique and not all products work here. Chipping can lead to a variety of problems for homeowners, including structural problems and costly repairs, not to mention lack of visibility.

If you own an apartment complex with peeling, your property will look neglected, driving away potential homeowners and guests. If you notice peeling or want to protect your property from it, contact Curtis Law Construction. Serving Kauai, HI, for nearly 50 years, its contractors have decades of experience in chipping repairs as well as other home-building projects. They are passionate about what they do and are always available to answer questions.

More seriously, if the structure is in an area that is accessed by the public or workers, then peeling can be dangerous in terms of falling debris or tripping hazards. If left unchecked, the husking will tend to accelerate and spread, so that eventually the structure could become unstable.

Therefore, diligent maintenance is of great importance and legislation imposes a duty to care for owners to ensure that structures are not hazardous to users. However, unsafe conditions still occur in the built environment. The possibility of objects falling from above is one of the most common safety issues related to structural and exterior wall systems of buildings. Typical root causes of such falling objects include poor detail, lack of clarity in drawings and specifications, errors in construction and lack of proper maintenance.

Due to the potential devastating effects of building materials falling from a structure, significant care must be taken to ensure that such failures do not occur. Most engineers and architects have probably observed some degree of chipping on the surface of a reinforced concrete structure or element. Descaling typically occurs as a result of stresses caused by differential movement of construction materials that are in contact with each other, or due to a progressive deterioration mechanism such as corrosion. As an example, the peeling of concrete from the corner of a foundation is common due to the different expansion and contraction characteristics of many building sheets compared to foundation concrete.

However, this condition occurs close to ground level and does not present a potential danger to aviation safety. Descaled concrete is a concrete that has been chipped, damaged, broken or flaked due to factors such as excess temperature, humidity, corrosion, weathering, mechanical pressures that stress concrete, or poor installation that causes concrete to wear out. Therefore, concrete peeling is an issue that needs attention. It should never be left exposed or untreated.

This is according to Indawo's managing director Geoffrey Jäck, who says that chipping is especially common in the Western Cape due to the high humidity in the atmosphere during the humid winter months. Conditions of insufficient coverage were widespread throughout the building's exterior, with potential safety risks identified on many of the balconies and with two (locations) identified as having immediate safety concerns, requiring rapid removal of peeling and loose concrete. Signs of chipping are a chipped and scaly surface, pieces of concrete coming out of the facility, and concrete that begins to crack. Robson Forensic offers in-house experts across the country who can apply first-hand knowledge and experience around chipping issues in their specific geographic region.

Both water intrusion and chloride intrusion promote corrosion of the reinforcing bars, resulting in an overall volumetric gain of the reinforced concrete element and thus exerts pressure on the concrete cover, eventually leading to flaking. Concrete peeling is the deterioration of concrete due to environmental factors, poor installation and other reasons. Measures can be taken to prevent it from flaking when the concrete is first poured, as the concrete mix will influence the likelihood that it will flake in the future. This lack of protection resulted in corrosion of reinforcing steel and localized scaling at multiple locations throughout the exterior of the structure where the roof was deficient.

Unfortunately, an adhesive plaster approach is often taken to repair peeling structures, without treating the underlying causes. Traditionally, the descaling of concrete can be detected by human visual inspection, which requires tools of tape measures or profilers and which must be identified by size and location. Corporate agencies, building owners and property managers should be aware of the dangers of husking in the high precipitation, wind and sea dew regions of the Western Cape. The combination of corrosion peeling and the delamination of concrete along the edges of the balconies and protruding edges of the building created conditions of rubble falling on the perimeter of the building and unsafe conditions below.
