Your new best friend (aka Concrete Repair Expert) assures you that the gap can easily be filled, restoring a strong foundation for the sidewalk. He checks the rest of the sidewalk for any similar erosion, and then leaves briefly, after suggesting you keep Grandma and her big dog inside the house for an hour or two. He returns shortly with his mudjacking equipment and concrete for the injection process.
After drilling a couple of small holes, he injects a compound made of sand, clay, cement, and grout into the ground beneath. After the existing gap between the dirt foundation and the sidewalk has been filled, your sidewalk will have the support it needs to be solid – and safe. When the mudjacking material hardens (in a couple of hours) you’ll be ready to take a nap while Grandma takes Tiny for a lovely spring stroll.
Most concrete, or buildings of similar material, will show some wear after a period of time – usually a long period of time. Regional weather and soil conditions have much to do with the longevity of concrete structures. In fact, the Greek Parthenon is still looking good after more than 2000 years. Sure, it’s had a few minor facelifts, but it’s still standing on its own.
Make it a habit to check routinely to see if sidewalks, driveways, foundations, and other concrete that support your home are in good condition. Take a peek at the soil that provides support for your home to check whether it is settling or otherwise degrading. If you find a possible issue, call your Concrete Repair Expert, even if you’re not sure. He will be happy to come out and have a look. Concrete issues that are caught early are much easier – and less expensive — to repair before damage occurs.
