Installing a permeable plastic paving grid as a shed base

  • Check with local authority about permissions for shed/outdoor room height and size
  • Plan size and position of your shed then mark out
  • Remove and stones, plants, grass etc
  • Dig out depending on shed size this should be enough so that when plastic grid is laid it is level with ground level
  • Ensure you have a compacted and primed sub base that is level
  • Add geotextile membrane LINK
  • Lay the plastic paving on top of the membrane
  • If you want extra load bearing you can then fill the grids with gravel.
  • Trim geotextile and possibly gravel around the shed base for a finishing touch.

Grids can be laid directly on the ground if needed and do not have to be filled so you can make your own choices with your garden situation.
