CHOOSING THE RIGHT BASE FOR YOUR SHED

Buying a high-quality steel or wooden shed is a great investment for your home, but even the best shed won't last if it's sitting on a bad foundation. Choosing the right base is critical for drainage, stability, and ease of assembly.

Concrete Slab

The Heavy-Duty Choice

A poured concrete slab is the most durable and permanent option available. It creates a solid, level floor that allows you to bolt your shed down — essential for steel units in windy conditions.

Best For

Large steel sheds, workshops, and heavy storage.

Pros

Extremely stable
Built-in floor
Rodent-proof

Cons

Highest cost
Permanent — cannot be moved
Requires professional skill to get perfectly level

Step-by-Step Installation

Paving Slabs

The DIY Balance

Using 2x2 or 3x2 paving flags over a bed of compacted sand and hardcore is a very popular middle-ground. It provides a solid surface that looks great in a garden setting.

Best For

Small to medium garden sheds.

Pros

Easier to install than concrete
Aesthetically pleasing
Can be moved if needed

Cons

Slabs can tilt or sink over time if the hardcore isn't compacted properly

Plastic Grid Systems

The Eco-Base

These interlocking grids are made from recycled plastic. You lay them on top of a thin layer of pea shingle. They are lightweight, incredibly strong, and allow for 100% drainage.

Best For

Small sheds, greenhouses, and temporary structures.

Pros

Fastest installation
Excellent drainage
Eco-friendly — made from recycled plastic

Cons

Requires the ground underneath to be already quite flat
Not ideal for very heavy industrial units

Our Expert Recommendation

If you are purchasing one of our Premium Metal Sheds, we highly recommend a Concrete Base using the "Picture Frame" method. Because steel sheds are lightweight, they must be bolted down to prevent movement during storms. A concrete base ensures the frame stays square, which keeps your doors sliding smoothly for years to come.
