Wide footing and extend below the frost line.
Footing for concrete block wall.
Mark the perimeter of the footing by planting two parallel lines of stakes.
Measure from the line to an adjacent walkway or building.
A poured concrete footing for concrete block or brick walls should be at least twice as wide as the planned wall.
The footing should be at least as thick vertically as the wall s planned width.
For example a typical 8x8x16 in.
How to pour footings for a block wall.
If necessary adjust the stakes so the line is equidistant.
Using the dimensions in.
Footings lie under the basement crawlspace or stem wall and transfer structural loads from the building to the supporting soil.
Always check local building codes for construction requirements in your area.
The footing dimensions will largely be determined by the size of the wall.
Drive additional stakes at each side of the line to.
Calculate the footing s dimensions.
Block would require a 16 in.
Prepare the concrete footing where the cinder block wall will sit.
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.
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.
Determine the planned wall s height and width.
