DIFFERENCE BETWEEN FOOTING AND FOUNDATION
Footing:-
A footing is the part of the foundation which supports it and transfers the load to the larger area on soil, so it safe the foundation from the settlement. It is generally provided with reinforcement and cast with concrete. Footings are majorly used in conjunction with shallow foundations commonly. The width and depth of any footing mainly depend on the type of soil and the size and type of foundation.
The footing is a structural member that safely transfers the load of the superstructure to the ground, and is the foremost construction member of the building.
The primary method of footing design is to transmit the load so that the size per area of the load transferred from the superstructure of the building is less than the strength that the ground can reinforce, that is, the bearing capacity.
With this function, the footing is a structure fixed between the ground and the column or wall directly above it, and the essential point in the essential design is to decrease the total quantity of settlement and control the occurrence of immobile settlement.
Types of Footings Following are the different types of footings, Continuous Wall Footing. Isolated Footing. Combined Footing. Strip Footing. Strap Footing. Raft Footing. Pile Footing.
Foundation:-
First and foremost, a structure or building consists of two main portions, the superstructure, and the substructure. The substructure is generally known as the foundation, as it transmits the load of the superstructure. Either columns or a wall is used to transmit the load of the superstructure to the foundation or substructure. The purpose of the foundation is to distribute the load to the soil with the right amount of pressure.
The foundation is the lowest part of any structure. Its key function is to transfer the load of the higher components to the soil. It plays an essential role in any structure.
There are usually two types of foundations (shallow foundations and deep foundations). A shallow foundation transfers the load of up to 1.5 meters and deep foundations transfer loads below the ground surface with more than 1.5 meters in depth. Shallow foundations are typically created for low-height structures or structures with a greater horizontal spread compared to their vertical height. It will also be required for a skyscraper that’s sitting on weak soil. It will need a deeper foundation only if there are concrete plans to extend this building vertically down the line.
The selection of foundation depends upon these factors that are listed below:
- Loads from building
- Type of soil
- Type of structures in the neighborhood
- Type of foundations
The types of foundations such as isolated foundations, combined footings, pile foundations, raft or mat foundations, etc. depending on the types of soils and loads from the buildings can be chosen based on the situation and needs.
Types of Foundation
- Shallow foundation
- Individual footing or isolated footing
- Combined footing
- Strip foundation
- Raft or mat foundation
- Deep Foundation
- Pile foundation
- Drilled Shafts or caissons
Differences between Footing and Foundation:
Sr. No. | Footing | Foundation |
1 | The footing is a formation which is in contact with the ground. | Foundation is a structure which transfers its gravity loads to earth from superstructure. |
2 | Footing can be analogized with the feet of the leg. | Foundation can be compared with legs. |
3 | The footing is a type of shallow foundation. | Foundation can be shallow and deep. |
4 | Footing includes slab, rebar which are fabricated of brickwork, masonry or concrete. | Foundation types include piles, caissons, footings, piers, the lateral supports, and anchors. |
5 | Footing reinforces support to an individual column. | Foundation is an extensive support because it gives support to a group of footings as an entire building |
6 | A number of footings repose on a foundation. | Foundation is the support that bears all kinds of loadings. |
7 | A footing is under the foundation wall. | Foundations are the basement walls. |
8 | Footing transmits loads directly to the soil. | Foundation is in direct contact with the soil and transmits it to the ground. |
9 | All footings are foundations. | Not all foundations are footings |
