What Is Foundation?
A foundation is an important & essential part of any house construction. It is simply the lowest part or structure of the house, which supports the entire structure. It takes all loads coming from the upper part of the house and transfers it to the ground safely.
Foundations are mostly constructed from strong material so they can hold the house in place even during earthquakes and cyclones. Therefore, they are generally made up of concrete which is the strongest construction material.
What is Need of Strongest and Best Foundation for a House?
The strength of a house depends on its foundation. The purpose of providing a foundation to the house is to hold the structure above it and keep it upright. On the other side, a poorly constructed foundation can be dangerous to the occupants and the neighborhood.
As an increasing trend of constructing high-rise skyscraper buildings, it has become all the more important to have powerful foundations.
There are three major function of foundation in house.
1) It major function is to support the load of the entire building
2) A strong and good quality foundation keeps the building standing while the forces of nature try to weaken it. Also, it provides safety and security during calamities such as earthquakes, floods, strong winds, etc.
3) The foundation must be built such that is restricting the entry of ground moisture to the upper part of the house in wall and flooring.
What is the Best Type of Foundation for a House
The following are best foundation types for a house,
- Isolated Column Footing
- Basement Foundation
- Slab Foundation
- Wall Footing Foundation
- Pile Foundation
1) Isolated Column Footing
The isolated column footing is one most simple and popular types of foundation used worldwide. It is generally used to support a single column. In the type of footing, each column is provided with a separate column footing.
- Isolates column footing most used for low rise house construction with fewer columns to support the structure. It is constructed by excavating a trench of the size of its footing and one column rises from that footing to the upper part of the house.
- This column runs up and joins the beam, it is called the column, beam, and foundation frame structure. The load is taken beam to column and column to the foundation, which is ultimately transferred to soil by footing.
This type of footing is used when
- Columns are not closely spaced.
- Loads on footings are less.
- Where the bearing capacity of the soil is high
There are different types of isolated column footing used as follows:
- Pad footing (with uniform thickness)
- Stepped footing (with nonuniform thickness)
- Sloped footing (trapezoidal section)
2. Basement Foundation
A basement is one of the best house foundations that typically has ceiling heights of 8′ and is often finished off as living or storage space.
Basements are one of the common types of foundations used in house construction, yet many people don’t know about them. The basement foundation is constructed using concrete to form a hollow space below the ground level.
So, Foundation is constructed by excavating a trench below the ground level. Basements generally have a depth of about 6 to 8 ft, depending on soil condition.
As the foundation is laid, it forms the bottom-most load-bearing element of your home and the floor of the basement.
A foundation basement consists of structural foundation walls that take a load of foundation footings running along the perimeter of the basement. These footings generally extend below the frost line, the depth to which the ground freezes in winter.
Basements may be partly or fully in-ground. Many people choose the second option as it often allows more natural light into the property, which has advantages when space is used for residential purposes.
The basemen are generally had electrical wiring systems, plumbing pipes, and your hot water heater.
There is a finished type of basement that comes up with drywall, flooring, a finished ceiling, and other comfortable features similar to what you’d find on the main level of the home.
Nowadays, the basement foundation mostly constructed from concrete or Mortared cement concrete blocks. Some old houses have a basement foundation built with stone walls.

3. Slab Foundation
A Slab foundation also called a slab on grade foundation is a solid concrete layer that rests on the ground.
Here, Grade is used for indicating ground level, and slab refers to the monolithic concrete pad.
This type of foundation commonly used in climates that do not experience ground freezing and thawing, as this can lead to cracks in the concrete and shifting of the foundation.
Slab foundations tend is less expensive than full basement or crawlspace foundations. Also, it offers better protection against termite infestation (also common in warmer climates).
One of the important drawbacks of slab foundations is that water supply and drainage pipes are embedded in the concrete. In case of any problem, the concrete slab must have to be cut into to access the pipes. Also, this type of foundation does not offer any storage or living space.
4. Wall Footing Foundation
This type of foundation is one type of pad or spread and strip footings over which the wall is erected and which are used to support structural or nonstructural walls to transmit and distribute the loads to the soil. All footing continuously runs along the wall.
On the basis of site condition and soil type, the thickness and size of the footing are decided. The width of the footing is kept around 2 to 3 times the width of the wall.
The wall foundation is constructed using plain concrete, or reinforced concrete stone, brick. The wall footing is best suited for small buildings.
5. Crawl space Foundation
A crawlspace foundation is a combination of a basement foundation and a slab foundation. A crawlspace foundation is less costly compares to other foundations and better choices for those who hope to remain conscious of the budget.
There are around 2 ft to 3 ft space is provides below the home will give its owner much-needed access to mechanical and plumbing fixtures. This will save time and cost of repair or maintenance for the year.
A crawlspace foundation is also a good choice for customers building on a sloped lot. Footings are mainly built to provide a level base on to build your home on.
Crawlspaces are mostly chosen in freezing in the environment because the space between the ground and the first floor acts as a barrier that protects from flooding. This is one of the best foundations for a house.
5. Pile Foundation
The pile foundation is one of the types of deep foundation is made of concrete, timber, or steel. Piles are like small-diameter column which is driven into or cast in the ground. We can also say that pile has depth more than a shallow foundation.
Pile foundation generally used where soil below the foundation not having sufficient bearing capacity to carry the load of building into deep soil up to hard strata.
Its most important feature is that the pile foundation is to transmit loads to the lower level of the ground by the combination of friction pile and end-bearing pile at the pile point or base.
Q.1 What is the Strongest or Best Foundation for a House?
Types of foundations suitable for the house is depending on the types of construction and type of soil available at the construction sites.
Type of construction means, it may be a high rise or multi-storeyed building construction or it may be low rise small house construction. For both types of construction, we have to choose different foundation types, which is proving to be economical for the owner.
Generally, high-rise buildings like apartment blocks may require a deep foundation around 5 to 20-meter depth and a low rise house construction depth of 6-8 feet is usually sufficient for residential properties.
