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