# How to Replace a Sidewalk
Instructions
-
-
1
Demolish and remove the existing sidewalk to make room for the replacement.
-
2
Dig down far enough to lay a 4 inch layer of gravel, followed by a 2 inch layer of sand and a minimum of a 4 inch layer of concrete.
-
3
Line the trench with inexpensive hardboard to create the edges for your sidewalk.
-
4
Make sure the bottom of the trench is level and lay the 4 inches of gravel. Lay the sand on top of it, water lightly and tamp tightly with either a compactor or a flat board nailed to a 2 by 4.
-
5
Pour your concrete and use a float to work it level by pulling a spare 2 by 4 across the hardboard. This will pull the concrete into areas and create a level surface.
-
6
Trowel the concrete smooth. Be sure not to overwork the concrete as this point, as it will weaken the end result of your walkway.
-
7
Broom over the top of the concrete to create a surface that is not dangerously slick.
