How to estimate concrete retaining wall.
If you re building a concrete block wall then check out our concrete block calculator.
Enter the length feet.
Use our block fill calculator to estimate the fill volume.
Volume of base slab l x b x h 10 x 3 x 0 2 6 m.
This calculator is to be used as an estimating tool only.
To calculate the volume of concrete in retaining wall we have to find out the following things from drawings.
The calculator will automatically estimate the number of cubic yards of concrete that will be required.
Estimate the amount of gravel needed to pack the trench at the base of the retaining wall.
Input length and width of the area.
To figure out how many rows you ll need divide the ideal wall height by the height of the block.
V l x h x t.

For example you can estimate a 10 wide by 2 high retaining wall and observe the materials required.
Enter the thickness inches.
So volume of retaining wall volume of base slab volume of stem.
Retaining walls footings or any other volume of concrete.
Multiply the cubic inches by the number of voids in the wall typically 2 per block.
If the wall is l feet long h feet high and t inches thick then the trench needs to be l feet long 0 12h feet deep and 2t inches wide.
Concrete is ordered by volume in cubic yards.
To simplify the process use our paver calculator to find out how many blocks you ll need.
Measure the length width and height of the void in inches then multiply to get the cubic inches of the void.
Enter the height feet.
Finally divide cubic inches by 46 656 to find cubic yards of concrete needed.
Estimate the retaining wall cost by adding the price per block.
How many retaining wall blocks do you need.
To use the concrete wall calculator simply enter the width length and thickness of your pour.
Depending on the typical climate for your location your retaining wall should have around 12 of gravel right behind the entire width and height of your wall to facilitate proper drainage.
To estimate how many blocks you ll need per row divide the total length of the wall by the length of the block.
Make sure to account for the first row being half buried.
