It depends on your local building codes and the depth of the frost line in your area.
Frost line depth is measured from grade (or lowest surface soil level pursuant to the foundation).
A shallow foundation is generally considered any foundation element that is 6 feet or less in depth. or the depth of foundation is equals to its width of the foundation. Examples are thickened edge slabs and grade beams that are supporting minimal weight.
if u assign a 0th level to root of binary tree then,the minimum no. of nodes for depth K is k+1.
1. Excavation of the soil up to required depth.2. Ramming the foundation bed.3. Cutting the concrete over the reinforcement.4. Laying the reinforcement over the the foundation bed.5. Pouring the cement concrete over the reinforcement.

Based on construction guidelines for a garage, the minimum depth of a below frost foundation is 3'11". That is the city of Oshawa guidelines.
2-3/4"
To find the depth of your foundation, you may want to check any paperwork that you received when you purchased the home. You may also find the info in the blue prints available at city hall in the records. The minimum depth of foundations can be 0.45m, but it is commonly 1 meter. It very well could be deeper, depending on the builder.
In most parts of the USA it is 2/32 of an inch.
Foundation is the underground or the substructure part of a building that transmits the load of the super structure to the ground safely. it is the lower part of building on which the whole structure rests. it may be made up of stone masonary, PCC or RCC. depending the width to depth ratio it may be a shallow foundation or a deep foundation. shallow foundations are used for smaller structures and shallow foundations are used for multistoried buildings where the load carried by soil is more.
@ least 3 feet

what is the depth
Minimum coverage for non vehicular areas; for conductors or cable not having a metal sheath or armour, under 750 volts, the required depth is 600 mm. For conductors or cable having a metal sheath or armour, under 750 volts, the required depth is 450 mm. Minimum coverage for vehicular areas; for conductors or cable not having a metal sheath or armour, under 750 volts, the required depth is 900 mm. For conductors or cable having a metal sheath or armour, under 750 volts, the required depth is 600 mm.
The minimum tyre tread depth in the UK is 1.6mm.
PCC-plain cement concrete of grades 1:5:10 or 1:4:8 proportion is used as leveling course in the foundation trenches to act as level platform for r.c.c footing for columns / masonry footing for load bearing walls.it also serves as separating layer between natural soil and footing so that any harmful chemical present in soil will not act on the footing.PCC has no structural importance.in case of of trences or pits excavated than the required depth,the extra depth should be filled with pcc of required grade at the expense of contractor to the required level to place the footing.
1.6 mm is the minimum
