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