Concrete Base for a Garden Shed: Why It Matters

Planning to install a new garden shed? Whether you're using it for storage, a workshop, or even a home office, one thing's for sure — it needs a solid, level foundation. The best option? A properly installed concrete base.

At JPT, we help homeowners across Hertfordshire, Bedfordshire, Cambridgeshire and North London prepare durable, professional-grade concrete bases for garden sheds of all shapes and sizes.

Why You Need a Concrete Base for Your Shed

A flat patch of grass or paving slabs might seem fine at first — but over time, an uneven or unstable base can cause major issues like:

• Doors and windows misaligning
• Damp rising through the shed floor
• Warping or rotting in timber frames
• General instability, especially in poor weather

A concrete base provides a strong, weather-resistant, and long-lasting platform that protects your shed and keeps it in great condition for years to come.

What’s Involved in Installing a Concrete Shed Base?

Here’s how we do it at JPT:

Site Clearance & Levelling

We remove grass, soil, debris or old slabs and level the ground to ensure a stable starting point.

Excavation & Sub-Base

A compacted hardcore base (MOT Type 1) is laid to support the concrete and improve drainage.

Shuttering & Formwork

Timber edging is installed to create a frame that shapes the concrete and ensures clean, level edges.

Concrete Pouring & Finishing

The concrete is mixed, poured, and levelled to your desired finish — often with a smooth float finish ideal for sheds, summerhouses or workshops.

Curing & Aftercare

We allow time for proper curing to prevent cracks, ensuring maximum strength and durability.

What Size Should Your Base Be?

As a rule of thumb, your concrete base should be slightly larger than the shed itself — typically 50mm to 100mm extra on all sides — and at least 100mm thick, depending on the size of the structure.
