A poured concrete footing for concrete block or brick walls should be at least twice as wide as the planned wall.
Footing for concrete block wall.
The footing should be at least as thick vertically as the wall s planned width.
Measure from the line to an adjacent walkway or building.
Footer drive a 24 inch wood stake 2 inches into the ground at each end of the proposed wall using a steel mallet.
Block would require a 16 in.
Prepare the concrete footing where the cinder block wall will sit.
Using the dimensions in.
Calculate the footing s dimensions.
The footing dimensions will largely be determined by the size of the wall.
If necessary adjust the stakes so the line is equidistant.
To construct a block wall you need to establish a solid footing that is a minimum of twice the width of the concrete block.
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.
Mark the perimeter of the footing by planting two parallel lines of stakes.
Always check local building codes for construction requirements in your area.
For example a typical 8x8x16 in.
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.
Footings lie under the basement crawlspace or stem wall and transfer structural loads from the building to the supporting soil.
