Concrete cancer is every homeowner’s nightmare. Once it’s caused damage and corrosion, your roof will be in serious trouble and need urgent intervention. To prevent it from happening, you need to keep your steel reinforcements from rusting and expanding due to water damage, so that the surrounding concrete doesn’t crack or corrode. It means you need to invest in the right concrete waterproofing supplies to keep all moisture out. As Concrete waterproofing distributors in Sydney, Waterproofing Direct have advice on how to protect your concrete roof effectively and prevent it from occurring in the first place.
Concrete sealers protect your roof from moisture and prevent mould and fungus build-up. It’s one of the more popular waterproofing solutions due to its ease of use. However, choosing the wrong sealer (or misusing the right one) could lead to expensive maintenance and repairs. Make sure you select a quality sealer as it will last up to five years until you need to reapply it. You can also opt for a permanent sealer but bear in mind that it leaves a matte finish and doesn’t come in many colours.
A waterproofing membrane will keep water out of your roof’s inner structure. PVC pre-formed sheet membranes are designed to handle intense winds and hard, excessive rain. The Wolfin sheet membrane is a polymeric PVC waterproofing system you can place loosely on your roof’s surface or chemically bond to it. It has incredible longevity and can deal with any weather condition or climate. Another option is Cosmofin membranes. These are also made of PVC but have a centre of non-woven glass that’s perfect for use in many commercial, residential, civil and marine construction projects. It is puncture and tear resistant and simple to repair.
Regular Inspections and maintenance are the best way to prevent concrete cancer from forming. Many things can make your building more vulnerable, even though you have waterproofing installed. If your building is near the ocean, it’s at higher risk of corrosion due to the salt in the air. Any structural defects present can also encourage concrete cancer to develop, so pay attention to the state of your building’s supporting structure.
Implementing the above measures is the best way to safeguard your concrete roof against concrete cancer and any other type of damage.
