A typical foundation wall minimum thickness of eight inches applies to walls eight feet or less with no more than seven feet of soil pressing against it. Foundation walls taller than eight feet with more than seven feet of soil pressing against it requires a larger foundation wall 10 to 12 inches in width.
House foundation thickness is an important factor in creating a sturdy, long-lasting house that can withstand the elements. The minimum house foundation thickness should be 8 inches for non-seismic or hurricane-prone areas but may need to be increased to 10 inches or more for homes in these areas.
Unbalanced backfill height shall not exceed 4 feet (1219 mm). 3. Minimum thickness for plain concrete foundation walls shall be 7.5 inches (191 mm) except that 6 inches (152 mm) is permitted where the maximum wall height is 4 feet 6 inches (1372 mm).
Depth Depth of foundation excavation to be at least 600mm below ground level at completion. Width Foundation must be at least 3 times the width of the wall it supports. Thickness Concrete to be at least 300mm thick.
The thickness (T) of the foundation should be:
150mm to 500mm for strip foundation.

This is, without a doubt, one of the most popular full-coverage foundations around. Despite having a pretty thick texture (which often makes for a cakey finish), it blends out beautifully on the face and can create a natural-looking base.
Footing thickness - 8 to 12 inches. Footing depth - varies based on frost line and soil strength (some footings can be shallow, while other must be deep)
Residential Buildings: Typically, houses and smaller residential buildings require shallower foundations. In most cases, a foundation depth of 900mm to 1200mm (approximately 3 to 4 feet) is sufficient.
For every 2 feet of adjustment to the width of the house, add or subtract 2 inches of footing width and 1 inch of footing thickness (but not less than 6 inches thick).
A typical foundation wall minimum thickness of eight inches applies to walls eight feet or less with no more than seven feet of soil pressing against it. Foundation walls taller than eight feet with more than seven feet of soil pressing against it requires a larger foundation wall 10 to 12 inches in width.
Under code, generally, one-story buildings with footings on undisturbed soil with LBVs between 1,500 and 4,000 should have a minimum width of 12 inches. Two-story buildings require a minimum of 15-inch wide footings for soil with a 1,500 LBV.
As a practical consideration, residential designers need to keep in mind that concrete foundation walls are typically 6, 8 or 10 inches thick (nominal).
Wet a Q-Tip so it doesn't absorb too much of your product and scoop the rest into a different container (they sell plastic sample containers at any beauty supply store). Then thin out foundation by adding a little moisturizer before you apply it.
The minimum depth of footings below the undisturbed ground surface shall be 12 inches (305 mm). Where applicable, the requirements of Section 1809.5 shall be satisfied. The minimum width of footings shall be 12 inches (305 mm).
Standard concrete floor slab thickness in residential construction is 4 inches. Five to six inches is recommended if the concrete will receive occasional heavy loads, such as motor homes or garbage trucks. To prepare the base, cut the ground level to the proper depth to allow for the slab thickness.
A slab foundation doesn't allow for enough stabilization for a second-story addition. A slab foundation—instead of footings supporting foundation walls—is constructed with what is called a trench foundation. A trench foundation means there are no footings underneath the exterior walls within the concrete foundation.
When you are building with concrete slabs, a general rule of thumb is the thickness is around 10 to 15 centimetres or 4 to 6 inches – but these measurements don't tell the whole story. To help you understand the needs of your next project, we'll cover: Concrete slab basics and necessary conditions.
All foundations shall extend to a depth of at least 50 cm below the natural ground level. The minimum depth of footing on sandy soil is 0.8 - 1 m, for rocky soil, it is 0.05 - 0.5 m and for clayey soil, it is 0.9 - 1.6 m.
Poured concrete is the strongest type of foundation for a house. Concrete is incredibly strong and durable, and it can be poured into any shape. This makes it ideal for supporting the weight of a house. Block foundations are also very strong, but they are not as flexible as poured concrete.
Footings shall be a minimum of 8 inches by 24 inches (203 mm by 610 mm) for houses two and one-half stories and less. The footings for a three-story building shall be 10 inches by 24 inches (254 mm by 610 mm).
A minimum of 12”inches deep for all footings and the width will be determined by the amount of stories, 12” inches for a single story, 15” inches for a two story and 23” inches for a three story. This is based on a soil bearing capacity of 1500(psf).
The footing is what's actually in contact with the ground, while the foundation is the structure that transfers the load to the earth. A simple way to visualize the difference when comparing it to the human body would be to view the footing as the actual feet of the legs and the foundation being the legs themselves.
Simple Gravel and Concrete Footing Design
The minimum footing thickness should not be less than the distance the footing extends outward from the edge of the foundation wall, or 6 inches, whichever is greater.
