ShedGrid Kits For All Sizes of Sheds

The original ShedGrid, a shed base system that allows water to quickly and efficiently drain away preventing rot and puddles. One of the most common failure points of a traditional timber shed is the base, which often rots due to being placed on a non-porous surface such as paving slabs.

The ShedGrid system provides a fast and easy to lay foundation for garden sheds, log stores, and garden storage bins. Unlike other foundations though ShedGrid provides incredible drainage, keeping water away from the shed base, helping reduce the risk of rotting or flooding.

ShedGrid Is superior when compared to other systems on the market. We not only use the genuine ShedGrid, but we also use the Premium version that is strong enough to support up to 44 tonne per square meter! Each kit comes complete with commercial grade geotextile membrane, to prevent weeds from coming through.

ShedGrid Installation

If installing on a flat level area installation could not be easier.

  1. Find a large flat area and clip the ShedGrid together to one large sheet the correct size for your shed. If your shed is particularly large you may need to split it into two or more sub-sections. It is important that the gird is the right way up, the webbed sections should be on the underside.
  2. Lay your membrane onto the ground where you want to install your shed and weight it down on the corners with stones.
  3. Get an assistant to help lift your plastic grid as an assembly and place it on top of your weed-proof membrane.
  4. Check the grid is level with a spirit level. If it is not level fine sand can be used on top of the membrane to lift the grid where there are any low points.
  5. Fill the grids using a shovel so that it is level to the top, and trim any excess fabric from around the edges with sharp scissors.

Your Shed Base foundation is now complete.

If you are not working with level ground there is an excellent guide here: that provides plenty of instruction on how to produce a foundation strong enough to park a car on.
