Concrete Removal and Repair
Are you bothered by a huge crack in your patio? Contemplating whether you should call a professional concrete repair service or fix the crack yourself? You may even be thinking of completely getting rid of the concrete! Well then, you’ve come to the right place.
Concrete is heavy! It’s impossible to make it disappear without a lot of effort. You’ll be needing heavy-duty equipment and specialists to safely and effectively break up this tough material. Once it’s broken up, you need to haul it away in a truck to clear up the debris. You’ll be needing a ton of help from professional contractors like JMC Concrete to get the job done.
Concrete foundations and slabs get damaged over time due to careless preparation of the under-surface and sometimes water penetration. Major and minor cracks happen to the concrete when the sub-surface or the foundation’s soil moves due to not being compressed enough.
Can cracked concrete be repaired? Yes, you can easily repair a minor crack. But to repair major cracks and modify the concrete foundations, that’s a job best left to a professional contractor. Even more so for highly technical jobs such as concrete removal. Luckily, JMC Concrete in East Melbourne offers expert solutions such as concrete restoration, removal, customisation, and more.
Minor cracks can be repaired by yourself at home with high-quality concrete repair products and following any provided instructions. However, it can be easy to make a mistake if you’re not an expert and you may end up damaging your concrete further. This could lead to spending more time, money and effort on fixing your concrete.
Most of the time, large cracks are connected to the undersurface of the slab setting. To repair them, you need to first remove the slab, then place a new bed of gravel, before finally topping it with a fresh slab. While it sounds simple in theory, the process is highly technical and can only be done by an expert. Little mistakes can mean having to repeat the process over again and your budget blowing out of proportion.
Major Causes of Concrete Cracking
Freeze-Thaw CycleConcrete is a highly porous material. Small cracks form and the surface may even start to flake when water gets absorbed and freezes. That’s why concrete in cold areas is more prone to cracking. If you are installing concrete in an area that is prone to frost and cold weather, you need to make sure appropriate measures are taken to prevent this kind of damage.
Plastic Shrinkage CracksThis kind of crack happens when the fresh concrete’s surface dries during its plastic state, before it gains its full strength. You may need to replace a section of the concrete or the entire slab.
Corrosion Reinforcing SteelBe careful not to pour deicing salts on the concrete as this would decrease its alkalinity. When this happens, chloride ions can penetrate into the reinforcing steel causing them to corrode. Once the steel bars rust, the concrete can expand causing it to pop off and crack.
Alkali-Aggregate ReactionAlkali-aggregate reaction or AAR is an effect caused when alkali hydroxide and the highly reactive aggregates found in the concrete meet. The concrete may then lose its strength when water or any other liquid gets absorbed.
