An EcoBase is an alternative base system designed to provide a stable foundation for certain garden buildings without the need for a traditional concrete or paving slab base. It can be a suitable option for a range of buildings, including selected sheds, garden rooms and log cabins, provided the ground conditions and building size are appropriate.
This article explains what an EcoBase is, when it is suitable, and what you should consider before choosing one.
What is an EcoBase?

An EcoBase is a modular base system made from durable, recycled plastic grids. These grids interlock to create a firm platform that supports the weight of the building when installed on properly prepared, level ground.
EcoBases are designed to:
Provide a stable, load-spreading foundation
Allow water to drain naturally through the base
Reduce the need for poured concrete in suitable situations
EcoBases are supplied as an optional accessory and are available for compatible buildings only.
When is an EcoBase suitable?
An EcoBase may be suitable if:
The building size and weight fall within the EcoBase’s load capacity
The ground is flat, firm and well prepared
You want a quicker or less permanent alternative to concrete
The EcoBase is listed as a compatible option for your chosen building
EcoBases can be used with some log cabins and garden rooms, as well as sheds, where the site conditions and product specifications allow.
When might another base type be more appropriate?
A traditional base such as concrete or paving slabs may be more suitable if:
The ground is uneven, sloped, soft or unstable
The building is at the upper end of size or weight limits
Maximum long-term rigidity is required regardless of ground conditions
In these cases, a more permanent base solution may provide greater tolerance for challenging ground conditions.
How does an EcoBase compare to traditional bases?
At a high level:
EcoBases offer convenience and reduced groundwork, but rely on good ground preparation
Concrete bases provide the highest level of rigidity and permanence
Paving slab bases can offer a robust alternative when correctly prepared
The best option depends on the building being installed and the conditions of your garden.
What do I still need to prepare?
Choosing an EcoBase does not remove the need for preparation. Before delivery:
The ground must be level and well prepared
The base must be ready before your building arrives
The EcoBase must match the external footprint of the building
