    Efficient Concrete Cancer Repair in Perth

    Concrete cancer

    If you're dealing with drummy and delaminated concrete, cracking to walkways, columns and stairwells, rust stains or flaking paintwork, you might be looking at a case of concrete cancer. Whether it's caused by the presence of contaminants or the action of the weather combined with atmospheric properties, concrete cancer can become expensive to deal with.

    Water penetration causes the concrete reinforcement to rust and expand. In turn, this places increased stress on the surrounding concrete, causing it to crack or spall. Over time, small hairline cracks can spread out, becoming both costly and dangerous to deal with. If left untreated, concrete cancer can cause concrete to become unstable, posing a serious risk of falling debris which can cause personal injury. The team at Comco Restoration have extensive experience treating concrete cancer and pride themselves on the effectiveness of their treatment. Our team will remove the spalled concrete, as well as expose any rusted steel bars back to clean steel.

    Then, we'll grind the steel back and treat it with inhibitors before sealing with a zinc-rich compound, preventing future rust and making sure the problem does not reoccur. Finally, we'll repair the concrete using specially modified polymer mortars, bringing it back to it's original profile.
