Why Choose a Concrete Base?
A concrete base provides a solid, level surface that resists movement and protects against damp and ground instability. It is the most reliable option for sheds and complies with British Standards for domestic foundations, giving you peace of mind that your structure will stand firm.
Planning Your Base
Start by measuring the footprint of your shed and adding at least 50 millimetres extra on each side to allow for clearance. It’s important to check your soil conditions before ordering concrete. For standard ground, Procon recommends Foundation 1 mix, while for aggressive or sulfate-rich soils, Foundation 2 offers added protection and durability.
Preparing the Ground
Excavate the area to a depth of around 100 to 150 millimetres. Lay a compacted hardcore layer of about 50 millimetres to provide drainage and stability. If required, add a damp-proof membrane to prevent moisture from rising through the base.
Setting Up Formwork
Next, create a square, level frame using timber boards. This formwork will hold the concrete in place while it sets. Double-check your measurements and ensure the corners are perfectly square to achieve a neat finish.
Ordering Your Concrete
Use the Procon concrete calculator to estimate the volume you need. Ordering directly via the Procon website ensures fast, convenient delivery to your site, saving you time and effort.
Pouring and Finishing
Pour the concrete evenly into the prepared area and tamp it down to remove any air pockets. Smooth the surface with a float for a clean finish. Allow the concrete to cure for 24 to 48 hours before placing any weight on it, ensuring maximum strength.
Pro Tips for a Perfect Base
For added strength, consider using fibres or admixtures in your mix. Always follow NHBC and local authority standards for compliance, and for larger sheds, reinforcement mesh can provide extra stability.
