# What Size Footing Should Be Used With A Basement Wall?

When building a basement wall, what size footing should be used?Thickness of the wall footings.Foundation walls of at least 6 inches in thickness are required for masonry or concrete construction.

• Unless otherwise specified, the minimum thickness of reinforced concrete footings will be 6 inches or 1-1/2 times the length of protrusion of the footing from the foundation wall, whichever is larger.

If the wall will be higher than 750mm, the footing should be three times the thickness of the wall. To be effective on most soils, footings should be at least 150mm (6′) deep, with the bottom 350 – 400mm (14-16′) below ground level at the very least. Footings that are thicker and deeper should be utilized on clay soil, on the other hand.

## What size footing should be used with a basement wall?

Footing should be three times the thickness of the wall if it is taller than 750mm high. On most soils, the bottom of all footings should be 350 – 400mm (14-16′) below ground level, with a minimum depth of 150mm (6′). It is necessary to build footings that are both thicker and deeper in clay soil.

## How to determine footing size?

The region underneath the column’s footing.As a result, the total load equals 2000 kN plus 200 kN, for a total of 2200 kN.Increased Load/Soil Bearing Capacity is the formula for calculating footing area.

• 2200/150 = 14.66 m2 is the area of the rectangle.
• Let’s figure out the size of each side of this square column footing: 14.66 m = 3.82 m = 4 m must be the length of each side of this column footing.

## What is the typical concrete basement wall thickness?

Soil may impose significant pressure on basement walls, and thicker concrete is more effective at resisting lateral loads than thinner concrete. Concrete basement walls that are 8 feet tall or less, and that have no more than 7 feet of dirt pressing against them from the outside, often perform well when they have an 8 inch thickness.

## How deep should a footer be for a concrete wall?

Concrete is the material of choice for the footer of any wall, regardless of the type of masonry material used to construct the wall. A standard footer is twice the width of a wall and has a depth that is equivalent to the width of the wall. The footer should be supported by a 6-foot-wide gravel base that is laid below the frost line.
