How much mini-mix concrete do you need?
When planning a DIY project such as a patio, shed base, or garden path, one of the most common questions is: “How much mini-mix concrete do I need?” Ordering too little can halt your project halfway through, while ordering too much increases costs and waste.
In this guide, we’ll explain step-by-step how to calculate the right amount of mini-mix concrete for your project, plus some tips on ordering and delivery.
Why choose mini mix concrete?
Step 1: Measure your area accurately
Concrete is calculated in cubic metres (m³). To work this out, you need three key measurements:
Formula:
Length x Width x Depth = Volume
For example: A patio base is 4m long x 3m wide x 0.1 deep.
Calculation: 4 x 3 x 0.1 = 1.2m³ of concrete needed.
Step 2: Adjust for project type
Different projects require different thicknesses:
Patio
75-100mm
Shed base
100-150mm
Driveway
150-100mm
Footings
150-300mm
Always check building regulations if you’re laying structural foundations.
Step 3: Add a margin for waste
It’s a good idea to allow for 5–10% extra concrete to cover uneven ground, spillage, or slight miscalculations.
Example from Step 1:
1.2m³ × 1.1 (10% extra) = 1.32m³ total order
Step 4: Mini mix vs. bulk deliveries
Mini-mix concrete is ideal if you need less than 2–3m³. Larger projects may be more cost-effective with full ready-mix loads.
