4 Popular Types Of Building Foundations In Nigeria by Pwanmaxmedia: 2:03pm On Oct 20, 2021
Looking to start a building project? You might need some information as to what to be aware of like building plans, architecture, budget, and types of building foundations.

Not to worry, this article will shed some light on basic types of foundation you need to be aware of and which is most suitable for your structure and type of building you are planning to erect.

Foundations provide support for structures, transferring their loads to layers of soil or rock that have sufficient bearing capacity and suitable settlement characteristics. Basically, a foundation is like a framework where your building are constructed on. Constructing the right foundation is an integral part to your success as a builder or commercial real estate investors. A foundation is the integral structural element of a building, bridge and other similar engineering structures that primarily transfers the loads of the structure to the soil or strata underneath it. The foundation provides stability as they serve as the point of connection between the structure and the soil or strata bearing the load. There are different types of foundation depending on the type/ complexity of structure and the strata directly beneath it.

As a beginner in the real estate investment sector, its important to understand the different types of building foundations and which types fits a specific type of building or soil. Foundations can be categorised as shallow foundations or deep foundations. Shallow foundations are mostly used for bungalows or simple structures with low bearing capacity. Deep foundations are necessary where the bearing capacity of the surface soils is not strong enough to support the loads imposed by a structure and so they need to be transferred to deeper layers with higher bearing capacity. In some something areas of Nigeria with weak or swampy soil, deep foundations are necessary to maintain the strength of the building

The most common types of building foundations you might come across are:
Strip foundation
Raft or Mat foundation:
Pile foundation
pad foundation
Strip foundation
Strip foundations are most suitable for soil which are of fairly good bearing capacity. They are mostly used for light structural loadings such as those found in many low-rise or medium-rise domestic buildings – where mass concrete strip foundations can be used. In other situations, reinforced concrete may be required. In simple terms, strip foundations are used in light weight constructions like bungalows and is not advised to be used for story buildings and high rises. Older buildings may have brick strip foundations.

Strip foundation is commonly used:

For bungalow construction.
When the soil is fairly of good bearing capacity.
When light weight construction is to be done.
Very broadly, the size and position of strip foundations are typically related to the wall’s overall width. The depth of a traditional strip foundation is generally equal to or greater than the overall wall width, and the foundation width is generally three times the width of the supported wall. This results in the load being transmitted at 45º from the wall base to the soil. In Eastern part of Nigeria where the soils are hard and compact also accepts the use of strip foundation. strip foundation are generally cheap compared to raft and more popular in the eastern part of Nigeria as an acceptable type of building foundation for low rise buildings.

Soil recommended for strip foundations are:

Rocky soil
Uniform firm and stiff clay Soil recommended for Raft foundations are:
Soft clay
Peat

Raft foundation
A raft foundation, also called a mat foundation, is a continuous slab resting on the soil that extends over the entire footprint of the building, thereby supporting the building and transferring its weight to the ground......... click here to continue reading: https:///3jkljf3
