A concrete block retaining wall is more for functionality than for beauty, unlike timber retaining walls. Regardless of your reasons for wanting a concrete block retaining wall you will want to know what it will cost you to finish. Use these steps to determine how you can estimate the cost of building a concrete block retaining wall.
1. Accurate Measurements
When you want to build a retaining wall of any kind you first need to know how big it needs to be in order to do its job. You need to know the length, the width, and the height. The wall should tower over whatever it is retaining by at least a foot as well as be in the ground by at least a foot.
2. Cost of Blocks
Call around your area to the stores that sell concrete blocks. Find out the cost per block, the size of one block, and if there is a price break for a large purchase. With accurate measurements and sizing information you can accurately determine how many blocks you need and the cost in total.
Rebar is used as a brace behind the concrete block retaining wall. You will need one rebar in the center of each column so be sure to include that in your calculations as well.
