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.

01

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

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
03

Timber Bearers

The Timber Shed Classic

For wooden sheds, timber bearers (pressure-treated 4x2 or 4x4 beams) are often used to lift the shed off the damp ground, allowing air to circulate underneath.

Best For

Wooden sheds and summerhouses.

Pros
  • Cost-effective
  • Prevents floor rot
  • Easy to install on slightly uneven ground
Cons
  • Not suitable for steel sheds
  • Not as secure in high winds
04

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.
