Cracks and holes in your concrete walkway create an uneven surface, which can lead to a tripping hazard. For this reason, it is important to fix the damage. However, depending on the severity of the damage, you need to know your options so you can choose the right repair method for your situation.
Repair Cracks and Holes
For minor cracks and small holes, you do have the option of repairing them. When it comes to repairing minor damage, you start by removing concrete chips and any dirt in or around the damage.
If you do not do this, then the repair material you use will not properly bond with the older concrete. The debris can create air pockets, which prevents the newer material from touching the existing concrete, and eventually new holes or cracks will form.
Before you can repair the concrete, you need to determine which repair material is best for your situation. Your first option is to place fresh concrete into the gap, which is a good option for holes. When you are dealing with smaller cracks, then you can use a latex-based concrete that you can pipe into the space.
If you are worried about the new material shifting for any reason, you can choose a resin-based mortar or non-shrink product. Both of these materials resist shifting because they are slightly flexible.
Remove and Replace Concrete
When the cracks or holes are larger, filling them in may not be your best option. In this situation, cutting out the damaged section and replacing it is usually a better choice. By doing this, you also have the ability to correct other issues, such as dips or hills that are making your walkway uneven.
With this process, the concrete needs to be cut away with an electric saw to create an even edge. Once the older concrete is removed, the ground below it needs to be prepped by leveling the soil, adding new gravel and placing rebar down. The rebar is what helps stabilize and support the new concrete.
To help prevent the concrete from flowing everywhere, a wooden frame is placed around the open hole. Then, the new concrete is poured and leveled. The leveling process is your opportunity to make sure that the concrete does not have any dips or hills.
Once you gather some additional information, you will be able to choose the right method for repairing your damaged concrete walkway. For professional help, contact a company like S&W Concrete.
