An Ecobase Fastfit plastic shed base kit suitable for 10ft by 10ft garden sheds.

Simple to install, the 10x10 plastic shed base can be placed straight onto grass, dirt, decking, patio or any other hard standing surface and provides a solid raised base for a garden shed, summerhouse, playhouse or garden building.

Provided as forty-nine 50cm square grids, each grid is easily secured together using the self-fastening connectors. They're a cost-effective solution as they're lightweight and compact enough to be delivered straight to your home and can easily be installed, extended or moved around as and when needed within your garden.

A water-permeable membrane is included as standard which is designed to be placed underneath the base to allow drainage and to inhibit the growth of weeds.

The inner cells can be filled with gravel, concrete or a mixture of both. Concreting the corners of the Ecobase will allow a solid place to anchor your building down if required. Wooden sheds with integral floors are usually heavy enough to place down directly on top of the grid without any anchorage, providing a long-lasting, durable and practical surface.

Ecobase Sizing Compared to Sheds/Structures

As Ecobases are made up of 50cm square grids and due to garden building sizes not being made to half-metre/one-metre measurements, some overhang of the base may occur around the edges of your structure.

Richard Starnes Asked:

How much gravel is required to fill the base?

We Replied:

Dear Richard Thank you for your question. Each of the forty-nine 50cm grids for the 10x10 size needs around 18kg of 10mm pea gravel to fill the cavities to the top. Although, please note that gravel is not needed to support the building – the grid is more than strong enough in its own right. I hope that this information helps. Kind regards, Lauren.
