What factors determine the type and size of foundations?
There are certain factors that should be considered during the selecting the foundation.
- Type of structure.
- Type of loading pattern.
- Location of the building (region of building)
- Soil condition.
- Water table level.
- Types of material that will used in construction.
- Lifespan of structure.
What determines the strength of a foundation? The quantity of loads depends on the type of structure, number of floors and material of construction. As the number of floors increases, the dead load and imposed loads also increase. Choice of material for construction such as reinforced concrete or steel construction also has impacts on foundation.
What factors should be considered in the design of foundation of any structure?

How do I choose a foundation for different soils?
Commonly, the selection of foundation type for a given structure is controlled by number of factors for example soil type, past site usage, adjacent construction, size of development process, limitations.
Selection of foundation based on different types of soil
- Uniform firm and stiff clay.
- Soft clay.
Which type of soil is suitable for any type of foundation?
Loam is the best soil type for construction due to its ideal combination of silt, sand, and clay. It combines the best of all their qualities into the ideal balance for supporting a foundation. Loam generally does not shift, expand, or shrink drastically and handles the presence of water very well.
What type of foundation is suitable for sandy soil?
Helical piers, also known as helical piles or helical anchors, are an ideal solution for building on all types of soil — especially sand.
What type of foundation is suitable for soft soil?
Soft clayey sand is prone to expansion and shrinkage. They have a low bearing capacity and are unsuitable for footing and strap foundation. In such case, Pile foundation is used. Piles are dug deeper until the stable strata is attained and is suitable for construction of substructure.
