EcoBase FASTFIT Shed Base Foundation *OFFER*

ECOBASE FASTFIT shed base foundation system is fast, easy-to-fit, lightweight, eco-friendly alternative to traditional concrete bases for sheds, cabins and greenhouses, and is one of the strongest shed base grid systems available. ​As the UK’s original plastic grid foundation system for garden buildings, EcoBase has evolved with the introduction of the FastFit system. Not only does it provide you with a firm, strong, long-lasting and well-drained foundation for garden buildings, capable of supporting 60 tonnes per grid when empty, it is now even quicker to install through the use of self-fastening push connectors to link grids together. EcoBase have a 10-year guarantee and these reusable grid tiles are lightweight and easy to handle, costing a fraction of the price of a traditional concrete base.

To create your shed base, simply join as many Ecobase FastFit grid tiles together as required. They are easily connected and come complete free weed suppressant ground membrane. The EcoBase FastFit tile is available in 1 size - approx. 500x500mm but can be joined together to make a foundation of any size, and can be easily cut to any shape using a normal hand saw. We recommend that Ecobases are fitted as a full base (we call this set-up Option-1), however you can remove some tiles for a cost saving if preferred (Option-2).

Simple Assembly

The EcoBase FastFit is very easy to assemble. Simply prepare a level area (the EcoBase can be laid directly onto grass, soil, builders sand or pea gravel), then lay out your EcoBase tile on top of the membrane, cut to size if necessary, then click each FastFit grid together... simple!


No Maintenance

Each EcoBase FastFit grid is made from 100% recycled plastic, and requires NO MAINTENANCE or preservative. These tiles are are designed to last, and are guaranteed to last 10-years!

Strong Quality Construction

​Each EcoBase FastFit grid is very, very strong, in fact it is TWICE AS STRONG as some of it's competitors and therefore needs no filling out with gravel or soil. They are made from UV stabilized, 100% recycled plastic and are manufactured right here in the UK. Each new profile grid measures approximately 500mm x 500mm x 40mm weighing just 1.4kg each, however thanks to it's patented design it has a huge crushability rating which can withstand 300 tonnes per sq. metre*. Check out our video below showing just how strong and environmentally friendly each EcoBase tile is.


Various Layout Options

We recommend that the Ecobase FastFit grids are joined together to make a complete base. This is the strongest and easiest way to create your foundation, and we call it Option-1. If you are trying to keep costs down as low as possible, then you can leave some spaces underneath your floor. It's not quite as strong, and it takes more planning as you have to ensure that your bearers are still being supported, however it can save you a fair amount of money, especially if it's a large base. We call this set-up Option-2. You can download our base design ideas here.

No Professional Assembly

The Swift EcoBase FastFit has been designed to allow even a novice DIY user to create a high quality, strong, long-lasting shed base without the need for a expensive professional service. 

Optional Extras
