Removing concrete by yourself can be quite a task. It can be very daunting, as well. Concrete is very resilient, but it is not at all immune to the damage that comes about with erosion, weather and also the passing of time. If you notice any cracks in the walkway or even the patio, I feel that it is the best choice of action if you address it. If you address it sooner than later, you will be getting ahead of the problem. You will also probably be saving a lot of money. Damaged concrete is something that can become very uneven over time, and it can cause a lot of problems. People could actually trip over it and hurt themselves. It can also create some rock debris that could be problematic.
Concrete actually has a lot of tell-tale signs and, it will show you when it is time for upgradation or even removal. A lot of these include very obvious cracking or even chipping.
There are a lot of other signs that can actually include uneven blocks and even warping as well. If the concrete has a certain colour, you need to make sure that it is taken care of. Surface level cracks can actually be mended with the help of fresh concrete. But, if the damage is something that has reached the deep levels, it is definitely time for you to tear it out and install a clean slate of concrete.
Before you go ahead and start up with your DIY concrete removal plan, I suggest you assess how thick the concrete is. If the concrete has more than 4 inches thick, or if it is reinforced with the help of wires, you will have to use power tools in order to break it. You will need tools because it will probably be a really tough to break. You may even need a sledgehammer.
Call the utility companies and make sure that there are no cable lines or even gas lines underneath the concrete that you are breaking. If you have no idea what you are doing, I highly suggest hiring a professional who knows what to do. You need to check if this particular concrete piece is connected to the foundation. If it is, it will have to be separated from the foundation.
You will obviously have to consider all of the safety precautions that should be taken into account. You will need to have safety glasses, heavy-duty work gloves, earplugs, steel boots to protect your feet and more. Concrete removal will cost you $1500-$3000 if you hire a professional to do it.
