Common Uses
Our shed bases are suitable for garden sheds, workshops, log cabins, garden offices, storage buildings, greenhouses, summerhouses, bike stores and general garden buildings. The interlocking grid system is also suitable for driveways, pathways, parking areas, paddocks and hard standing where ground protection and drainage are required.
Installation Guide
For shed and garden building bases: lay the grids on a firm, level surface — on lawn, bare ground or concrete. No membrane is required under a building that has a floor as weeds will not grow where there is no light. Click the grids together to fit the required area. Any visible grids at the edges can be filled with stones for a neat finish or trimmed with a jigsaw.
For driveways, paths and hard standing: prepare the area to 4cm depth, lay a membrane, then click the grids on top. Fill with gravel, sand, turf or other suitable medium packed tightly to the top of the grids. Allow 15kg of gravel per grid.

FREQUENTLY ASKED QUESTIONS
What is a shed base grid?
Interlocking plastic grid panels that sit on the ground to create a firm, level, free-draining base for sheds, summerhouses, greenhouses and log cabins. An alternative to concrete that is faster to install and permeable.
How is a shed base installed?
Level the ground, lay a weed membrane, then click the grid panels together. Fill with gravel if required. The base is ready immediately — no curing time like concrete.
Does a shed base grid need gravel?
Optional. The grid can be used empty on firm ground, or filled with pea gravel for additional weight and drainage. Gravel fill also prevents the grid panels from shifting.
What sizes of shed base are available?
Check the product page for the available grid sizes. Multiple panels can be combined for larger bases.
Is a grid base as strong as concrete?
For sheds and light garden buildings, yes. Grid bases distribute load across the ground surface and are approved by most shed manufacturers. For very heavy structures, concrete may be more appropriate.
