Installing a concrete path is a challenging task but not impossible. Before you begin your project check with your local jurisdiction to determine what permitting requirements affect your home if any. Once you know the engineering requirements and have proper permits from the city it is time to begin your project.
Your first task is to map out your walkway. When possible, use spray paint to draw out your path. Once you have your path mapped out you will want to dig out your walkway. About 4 inches deep should work well. Once you have your path dug out you will need to evaluate your soil. Soft and sandy soils need to be amended so that they can bear weight. This can be done by adding clay to sandy soil and sand or gravel to loamy soil. If you have any doubts contact a local contractor or civil engineer to evaluate your base. An unstable base will lead to failure. To ensure that your path conforms to the width and length you want, you need to frame it with 2×4’s. Use small wooden stakes to hold your boarders in place. Do this after you have dug out your walkway. Once you have the proper depth and soil consistency you will need to compact the soil.
Install reinforcing steel to help increase the strength of your path. You can use the number 4 rebar on 12 inch centers. If this sounds foreign you can usually receive direction and clarification from your local hardware store. Plan your pour before the cement truck arrives. Make sure you level the surface as flat as possible. It is typical to avoid a completely smooth surface. Running a broom over your concrete slabs can accomplish this so that your concrete will have some texture and allow some grip for people. Once your concrete is poured, you will need to cut control joints every 4 to 5 feet along the length of the walkway. This can be done with a tool called a groover. Your last step is to cure the concrete. You can accomplish this by using a layer plasting sheet or by using a chemical curing compound. Either of these should prevent the concrete from drying too quickly. You should stay off the new concrete for at least four days before testing out your new path.
