Block would require a 16 in.
Footing for concrete block wall.
How to pour footings for a block wall.
Wide footing and extend below the frost line.
Prepare the concrete footing where the cinder block wall will sit.
Drive additional stakes at each side of the line to.
To construct a block wall you need to establish a solid footing that is a minimum of twice the width of the concrete block.
If necessary adjust the stakes so the line is equidistant.
The footing width should be between two and three times the width of the wall to be built on top of it.
Always check local building codes for construction requirements in your area.
Determine the planned wall s height and width.
Calculate the footing s dimensions.
Footings lie under the basement crawlspace or stem wall and transfer structural loads from the building to the supporting soil.
Footings are typically cast in place concrete placed beneath the frost depth to prevent damage resulting from heaving caused by freezing of water in the soil.
Start the concrete footing by digging the area of the wall a few inches below the frost line the maximum depth in the ground below which the soil does not freeze during the winter.
Using the dimensions in.
Footer drive a 24 inch wood stake 2 inches into the ground at each end of the proposed wall using a steel mallet.
The footing should be at least as thick vertically as the wall s planned width.
The footing dimensions will largely be determined by the size of the wall.
Measure from the line to an adjacent walkway or building.
