Hey,
We all know that among the most crucial components of the construction, is the foundation. It gives the structure stability and transfers the whole weight of the building to the soil. But did you know that there are actually two types of foundation: shallow foundation and deep foundation. They are essentially divided into categories based on the extent to which the groundwork is offered. Now if you’re wondering how I know all this, then let me tell you, my father is an architect and he keeps me up-to-date with all the architectural knowledge that he can share with me. So, I am going to help you with your query and tell you the difference between shallow and deep foundation.

The contrasts between shallow and deep foundations are numerous. The concept, thickness of foundation, price, practicality, method of transfer of load, benefits, disadvantages, types, etc. are the main sources of variations among deep and shallow footings.
The key distinctions between shallow and deep foundations are shown in the following table:
| Sl. No. | Criteria | Shallow Foundation | Deep Foundation |
1 |
Definition |
Shallow foundations are those that are built close to the earth's surface or transfer loads at a shallow depth. |
The term "deep foundation" refers to a foundation that is set at a higher depth or transfers loads to deep strata. |
2 |
The depth of the foundation |
Typically, a shallow is no deeper than the footing or about three metres deep. |
More substantial than the thin foundation. |
3 |
Cost |
It is cheaper |
They are more expensive |
4 |
Feasibility |
Easily constructible |
More complex to construct |
5 |
Mechanism of load transfer |
Shallow foundations primarily use end bearing to transfer loads. |
With a few exceptions, such as end-bearing piles, deep foundations rely on both ends carrying and skin friction. |
6 |
Advantages |
Construction materials are readily available, less labour is required, the process is straightforward and reasonably priced, etc. |
A deeper foundation can be used, it offers lateral stability and resists uplift, it works when a shallow foundation is impossible, it can sustain a large amount of weight, etc. |
7 |
Disadvantages |
Settlement potential, is typically present in light structures that are vulnerable to lateral loads, etc. |
Deep foundations might be more expensive, require expert workers, involve intricate construction techniques, take longer to complete, etc. |
8 |
Types |
Various types of foundations exist, including isolated, strip, mat, and integrated foundations. |
Caissons, pier and pile foundations, etc. |
These can be precisely said to be the key difference between Shallow and Deep Foundation.

Deep Foundation Vs Shallow Foundation
If you ask me to define shallow and deep foundation, I would say deep foundations carry the weight of the structure down to deeper layers of rock or soil, while shallow foundations carry the load to the soil close to the surface.| Criteria | Shallow Foundation | Deep Foundation |
| Depth of Load Transfer | Near-surface soil within a few meters of the ground | Extends to deeper, more stable soil or rock layers |
| Types of Foundations | Spread footings, mat foundations | Pile foundations, drilled shafts, caissons |
| Load-Bearing Capacity | Suitable for lighter structures and moderate loads | Ideal for heavy structures and high vertical loads |
| Construction Complexity | Simple construction processes and equipment | More complex construction processes and specialized equipment |
| Cost | Generally more economical | Typically more expensive due to specialized construction |
| Time Efficiency | Shorter construction timelines | Longer construction timelines |
| Applicability | Commonly used in residential buildings, small structures | Preferred for high-rise buildings, bridges, and complex structures |
| Vulnerability to Settlement | Prone to uneven settlement, especially in variable soils | Minimizes the risk of settlement and subsidence |
| Environmental Impact | Lesser environmental impact | May have a greater environmental impact, especially in sensitive areas |

Most of you must know that one of the most crucial components of construction is the foundation. It gives the building support and distributes the entire load from the structure to the soil. Generally, there are two types of foundation in the construction sector: Shallow Foundation and Deep Foundation. The depth of the foundation and the type of soil they are built on are the key differences between the two. Let’s check out what is different between shallow and deep foundation below.
Difference between Deep Foundation and Shallow Foundation
Harsha Vikas and Bhat Suresh have already provided the comparison table for deep and shallow foundations. Let’s check out the more difference here:
Shallow Foundation:This foundation is frequently utilised when the soil around is stable enough to sustain the building.
This is used for small to medium-sized constructions and may be built rather affordably.
Typically, a footing for this foundation is made by digging a trench in the earth and putting concrete into it.
This is divided into 2 categories: Raft and Footings.
Deep foundations are used when the soil close to the surface is weak or unstable.
It can shift the weight of the structure deeper.
For huge buildings, bridges, and other structures that need extra support, deep foundations are used.
They are more costly and challenging to build than shallow foundations.
This is categorised into 3 categories: Piles, Piers, and Caissons or Well Foundations.
The extent of the foundation and the type of soil they are built on make up the majority of the differences between shallow and deep foundations. I hope you understand how to differentiate between shallow and deep foundation.

The lowest load-bearing element of a structure is the foundation. It serves as the structure's point of connection with the earth, or in simple terms, it transfers the burden of the structure to the ground, and it is normally hidden below ground level. Foundations can be broadly categorised into two categories: deep and shallow. You will get to know here the difference between deep and shallow foundations.

The following points will help you know the shallow and deep foundation difference:
Shallow Foundation |
Deep Foundation |
The weight is transferred to the soil at a shallow depth in shallow foundations. |
When dirt near the surface is able to support the structure's loads effectively, shallow foundations are used. |
Open excavation is used to build these foundations. This is one of the main points in shallow foundation vs deep foundation. |
These foundations are built by drilling or boring with the aid of mechanical devices. |
It is possible to see inspect construction at any depth because the foundation is shallower. |
It is impossible to visually assess a construction at a deeper level. |
There is very little soil disturbance. |
Soil disturbance covers a wide area along the length of the deep foundation. |
When dirt near the surface is able to support the structure's loads effectively, shallow foundations are used. |
When the soil close to the surface is unstable and weights must be shifted to more suitable soil or rock at greater depths, deep foundations are used. |
This is all you need to know about the difference between deep and shallow foundations.
