The initial part of any building is the foundation. The foundation must be built correctly for the durability of a building and to ensure that it is stable, safe and built for longevity. Without a stable foundation, your building will not last.
Here at Wilsons Groundworks, we’ve got vast experience in groundworks in Bristol and the surrounding areas. Read on below as we discuss the importance of a building foundation and why you need to get it right.
What Is A Building Foundation?
A building foundation sits between the building structure and the ground. It’s the lowest part of a building.
The function of a building foundation is to distribute the load of a building across the soil and support the entire structure above it, anchoring it into place.
Why Are Building Foundations Important?
Building foundations are vital to a building’s durability. Failure to properly install them can lead to various issues.
Support and Stability
Having correctly built foundations will evenly distribute the weight of a building across the ground, preventing uneven settling or collapse.
Load Bearing
The foundations of a building transfer the load from the walls, floors, and roof to the ground, including both the live loads of people and furniture and the dead loads of the structure itself.
Prevent Settling
A strong foundation will prevent settling. Differential settlement causes cracks and structural damage over time.
Protection Against Nature
Foundations will anchor a building against wind, floods and earthquakes.
A Moisture Barrier
A correctly built foundation will also offer damp-proofing and waterproofing, stopping groundwater from entering a building.
Insulation and Energy Efficiency
A foundation can also help offer thermal efficiency, reducing the need for heating and cooling.
Types of Building Foundations
Typically, building foundations are split into two categories: shallow and deep. These two foundation types are used in different scenarios.
Shallow Foundations
Shallow foundations are placed nearer the surface to transfer the weight load of a structure at shallow depths. Generally, around 1.5-3 metres deep, these foundations are typically cheaper and easier to build. It’s important to keep in mind that shallow foundations are weaker when it comes to supporting lateral loads.
Deep Foundation
Deep foundations are placed much deeper than shallow foundations. This is so they can transfer the structural load onto the deep layers of rocks deep in the ground. These foundations are much more complex and can support heavier loads, making them more expensive initially.
The Importance Of Properly Installing Foundations
A strong building foundation is vital as it is the backbone of a structure.
Cutting corners during the foundation installation process can lead to long-term problems with the building structure. Without a correctly built foundation, the building above could shift, crack or collapse, leading to costly repairs or injury to those inside or loss of life.
Think of it like a domino effect. Inadequate foundations lead to an unstable base, support beams and walls to follow suit. This decline of a building’s structure is referred to as subsidence, settlement or differential movement.
Why You Should Work With A Professional
Working with a professional is crucial when constructing a strong building foundation. When so much lies on getting it right, a professional can ensure that your foundations are built to legislation and are of high quality. This includes selecting the right foundation type for the project, the soil conditions and structural requirements.
