Yes, a slab house typically requires a footer, also known as a footing. The footer serves as a stable base that helps distribute the weight of the structure and provides support, preventing settling or shifting over time. It is usually poured below the frost line to protect against ground movement due to freezing and thawing. Properly designed footers are essential for ensuring the long-term stability and durability of the slab foundation.
is it a footer that is poured the same time as the slab?

The tfooter and theader elements are used to define the elements inside of a table that make up that tables header and footer respectively. They are particularly useful in complex tables, where the header and footer might otherwise not be obvious.

The recommended depth for the footer when constructing a concrete slab is typically around 12 inches.
The best way to remove odors from the house slab is to thoroughly wash the house. Airing the house is the other way of removing the odor from the house slab.

If you mean how wide a footer you need, only as thick as the old existing footer. Residential footers are usually way over designed, so there is no reason to make it wider. If you do mean thick, a normal house footer is 8" thick. If you are actually underpinning an existing footer, the dinensions are in front of you as you excavate under it for underpinning.??? Don't make it anymore complicated than that.

As a concrete contractor in Sydney, I’d say 100 mm is generally the practical minimum thickness for a standard residential concrete slab-on-ground. However, the correct slab thickness depends on several factors, including the soil classification, house design, loads, reinforcement requirements and footing system. In Sydney, some homes may require thickened sections, edge beams or engineered footing designs, particularly on reactive clay soils or for heavier construction. The National Construction Code requires residential footings and slabs to comply with relevant standards such as AS 2870, while NSW also has specific requirements for slab construction. For any new house foundation, I recommend getting a proper soil test and engineered slab design rather than choosing a thickness based on a general rule.
The recommended concrete slab thickness for a house foundation is typically 4 inches to 6 inches.
It is the concrete "footprint" of your house / building. The size of said footer determines how much load it will be able to handle and thus how many stories are allowed on the building.

If you go to the monolithic dome site you will be able to check the size of footers for the over all size of your dome. Rev.Dick Freeman domeman3@earthlink.net
