Wall sq ft block size.
How much concrete to fill cinder block wall.
When reinforced with steel and filled with concrete a rock solid wall can be built to withstand the elements.
To estimate how much grout is needed to fill those voids you need to find the volume of each void and multiply that by the number of voids in the wall.
Multiply the cubic inches by the number of voids in the wall typically 2 per block.
Concrete block also known as a concrete masonry unit and sometimes called a cinder block typically has one or two holes or voids to reduce the weight of the block.
To use the block wall calculator simply enter the height and length of the wall click on whether you are filling an 8 inch or 12 inch wall then click on the calculate button.
The calculator will estimate the number of cubic yards that will be required.
Use our block fill calculator to estimate the fill volume.
8 inch 12 inch bags required.
6 8 12 cubic yard required.
Measure the length width and height of the void in inches then multiply to get the cubic inches of the void.
5 to the total for waste.
A single bag should go a long way in most projects but for a closer estimate measure the length width and depth of the holes in your block.
While it does not take very much to completely fill them the amount of concrete that you need will obviously have a lot to do with how many blocks that you have.
Blocks are stacked one upon the other to form everything from exterior walls to retaining walls.
Finally divide cubic inches by 46 656 to find cubic yards of concrete needed.
