EcoBase 15′ x 9′ Heavy Duty Garden Foundation Kit

The EcoBase 15′ x 9′ Heavy Duty Garden Foundation Kit is the original plastic grid foundation system designed specifically for garden buildings. This eco-friendly alternative to traditional paving flags or wet-mix concrete is crafted from recycled materials, providing a firm, strong, and long-lasting base for your outdoor structures.

Ideal for most 5 x 3m (15 x 9ft) buildings, the kit features 60 grids that easily snap together for quick installation. It includes a permeable membrane (approximately 16ft 4in x 9ft 10in) to suppress weed growth, ensuring a clean and tidy foundation. The lightweight grids allow for easy handling, while their robust design guarantees a reliable base for various applications, including garden sheds, summer houses, and bike storage.

This heavy duty building base system is cost-effective, as it requires less preparation time and costs less than traditional concrete pouring. Once positioned, it’s ready to use immediately, eliminating the need for concrete curing time. The raised gripping points ensure stability, while the drainage perimeter can be filled with pea gravel, creating a French drain to prevent water buildup.

Specifications include a grid footprint of 500 x 500mm, a grid height of 40mm, and a load capacity exceeding 300 tonnes per square meter. Made in the UK from 100% non-toxic, recycled plastics, this foundation system is rot-proof, chemically inert, and reusable.
