Can Concrete Cancer Be Cured? - A Comprehensive Guide

Concrete cancer, also known as spalling or concrete detachment, is a common problem in buildings and other structures. It occurs when the steel reinforcement embedded within the concrete member rusts, leading to the deterioration of the concrete surface. If left untreated, it can compromise the integrity of the structure and jeopardize its ability to withstand external forces. Fortunately, if the damage caused by concrete cancer is moderate, it can be cured.

The process involves removing damaged concrete, cleaning and replacing oxidized and exposed steel, and filling in cracks. Once the underlying steel and concrete have been repaired, they must be properly cured with specialized coatings. It is important to watch for telltale signs of concrete cancer, such as leaks, bubbling paint, rust spots, or cracks. If you own a building that already displays signs of concrete cancer, it is best to act quickly and deal with the problem.

Professional remedial services can conduct inspections and prepare reports on concrete cancer in buildings, and even establish repair methodologies and supervise and manage the repair process project. Dealing with concrete cancer is not a DIY job. It requires penetrating the concrete sufficiently to reach the rusted steel reinforcement; completely removing rust; treating the steel; and waterproofing the steel to ensure that the problem does not occur again. Depending on the severity of the problem, concrete repairers may use a technique called “crack injection” to create a water diverting membrane or more invasive action may be needed. For situations where concrete carbonation and low concrete coverage are the problem, engineers might recommend using a polymer-modified repair system. This treatment is used for concrete cancer caused by low concrete cover or by carbonation of concrete.

It involves immersing a material such as Resistain in concrete to a depth of 10 mm. This material attaches to the concrete structure at the molecular level and forms a water repellent barrier. We specialize in delivering Concrete Cancer & Concrete Splalling solutions to residential, commercial, industrial and civil sectors across Sydney. As soon as concrete detachment is detected, it must be properly repaired, otherwise it compromises the integrity of the structure. While there are some obvious signs of particular cancer, it is sometimes so hidden that it can only be confirmed by a licensed structural engineer. If you have suspicions about your building or would like more information about it, do not hesitate to contact our repair division.

Prevention is always better than cure when it comes to concrete cancer - so make sure you keep an eye out for any telltale signs!.
