Cement walkways and driveways might seem like they are very sturdy, but over time, they can shift, crack, and wear down. If your driveway no longer is even, you might think that you will need to spend a lot of money, have the whole thing ripped up, and be inconvenienced for a long time for it to be fixed, but that is not necessarily the case. There is an option called mudjacking that can help in certain situations. Mudjacking is accomplished by drilling holes in the existing cement and then pumping in a mixture of cement, first and water. This will level and raise the existing cement and make your driveway like new again.
There are some dangers with this process since it could damage underlying pipes and wires, so you should ensure that you know where these run before you consider whether or not mudjacking is something that will work for your driveway or walkway.
