Uneven sidewalks can pose tripping hazards and accessibility issues. To fix them, follow these steps:
-
Identify the damaged area and remove any loose debris or obstacles.
-
Excavate the area to a depth of at least 4 inches, ensuring the edges are vertical.
-
Create a form using plywood or stakes to define the shape and size of the patch.
-
Pour concrete mix into the form, ensuring it’s level with the surrounding sidewalk.
-
Smooth and compact the surface using a trowel or float.
-
Remove the form after 24-48 hours and allow the patch to cure for at least 2 weeks before use.
