When starting a construction project such as a new house, extension, or structural feature in your garden, the most important part of the build happens before anything is visible above the ground.
Strong foundations ensure the long-term stability and safety of the entire structure. One of the most critical elements of any foundation system is the concrete footing.
Footings distribute the weight of the building and transfer the load safely into the ground. Using the correct concrete mix for footings is essential to ensure the structure remains stable and durable for decades.
In this guide, the team at Q Mix Concrete explains what concrete mix works best for footings, when reinforcement is required, and why choosing the right strength matters.
What Are Concrete Footings?
Concrete footings are structural supports that form the base of foundations. They are typically created by digging trenches in the ground and filling them with reinforced concrete.
Their main purpose is to:
- Spread the structural load of the building
- Prevent settlement or movement
- Provide a stable base for foundations or walls
Footings are usually installed before foundation walls or slabs are constructed.
When Are Concrete Footings Needed?
Footings are required for many types of construction projects, including:
- New houses or building extensions
- Garden walls or retaining walls
- Decking structures
- Fence posts
- Pergolas or outdoor structures
- Small garden buildings
They are particularly important when building on soft or unstable soil conditions, such as clay or loose ground, where additional structural support is necessary.
Best Concrete Mix Strength for Footings
The strength of concrete used for footings is usually measured in PSI (pounds per square inch) or concrete grade.
The ideal mix depends on whether reinforcement is used.
Reinforced Concrete Footings
If your footings include steel reinforcement bars (rebar), a stronger mix is recommended.
Typical strength:
3,500 – 4,000 PSI concrete
This provides the durability and structural strength needed to support heavy loads from buildings or structural walls.
Non-Reinforced Concrete Footings
For lighter projects where reinforcement is not required, a slightly lower strength mix can be used.
Typical strength:
Around 2,500 PSI concrete
This is commonly suitable for smaller residential structures such as fencing, decking posts, or garden features.
Why Reinforcement Is Often Used
Steel reinforcement bars (rebar) are frequently placed inside footing trenches before pouring concrete.
Rebar helps:
- Improve structural strength
- Reduce cracking
- Handle tension forces within the concrete
When combined with the correct concrete mix, reinforced footings provide a strong and dependable base for construction.
Preparing the Ground for Concrete Footings
Before pouring concrete, the ground must be properly prepared.
Typical preparation steps include:
- Excavating trenches to the correct depth and width
- Checking soil stability to ensure the ground can support the structure
- Installing reinforcement bars if required
- Ensuring proper drainage conditions
Once the trench is ready, concrete is poured to form a solid foundation base.
Why Ready Mix Concrete Is Recommended
For structural work such as footings, ready mix concrete is usually the best option.
It ensures:
- Accurate strength grading
- Consistent quality
- Correct water-cement ratio
- Faster installation on site
Using professionally mixed concrete significantly reduces the risk of errors that can occur when mixing concrete manually.
