Poured Concrete Wall Thickness

Increasing the strength of the concrete mix or the thickness of the wall increases the wall s capacity.

Poured concrete wall thickness.

Holding up under pressure. The calculator will automatically estimate the number of cubic yards of concrete that will be required. To achieve a strong wall keep the layers of concrete 20 in 51 cm thick or less. The length of the base slab is usually about 50 to 70 of the total height of the wall bottom of base to top of stem.

The taller the wall the thicker it must be. So taller walls in heavier soils should be made thicker or with stronger concrete. Concrete is ordered by volume in cubic yards. When planning the thickness of foundation walls.

Pour the concrete directly into the wood form using a chute or hose attached to the mixer. For cantilever and counterfort walls the stem thickness at the base is often about 10 of the total wall height as is the base slab thickness. Table 4a is based directly on the aci method but for table 4b the author has applied a reduced strength reduction factor a factor of safety. In general poured concrete basement walls that are 8 feet tall or less and have no more than 7.

Poured concrete foundation walls that are less than 8 feet tall and have soil outside that is 6 or 7 feet deep against the wall can often be 8 inches thick and function quite well. To use the concrete wall calculator simply enter the width length and thickness of your pour.
