There’s nothing quite as satisfying as looking at a perfectly-built garden shed and knowing that you are the DIY superstar behind the project. But, as any master creator knows, the devil is in the detail and it’s crucial to get the right flooring base for your shed. You can’t simply stand it on the ground because the wood will get damp and ruined in no time at all. In the past, you’ll probably have suffered the pain and expense of getting concrete laid or grappled with paving stones. You’ve learned your lesson on that one, right? So, let’s get serious and show you how to prepare a garden shed floor base so robust that your neighbours will be begging you to build theirs too.
Watch our video and then use our step-by-step guide below.
Materials you will need:
- Tape measure
- Trowel and spade
- Spirit level
- Long piece of timber (optional)
- Weed killer
- Weed suppressing fabric
- Floorbox Ground Reinforcement Flooring (Geogrid standard, Geogrid premium or Durapath)
- 10mm Stone (20kg bag per half-metre of flooring)
Step one – Locate the perfect shed space
Chances are that you’ve had your eye on the perfect garden shed spot for ages. If you are still not sure where it would work best, look at a piece of ground in your garden that is as level as possible. Once you’ve identified the right site, get the dimensions of your shed and mark out the area according to your requirements.
Step two – Clean-up time
Sorry to break it to you, but there’s a less fun job to do before the good stuff begins. You’ll need to clear any grass or debris from the site. Ideally, you’ll have removed anything that isn’t soil by the time you’ve finished this step. We recommend tuning your radio to Planet Rock to get you in the right mood – there’s nothing like a bit of headbanging to propel you through a dull job.
Step three – Set your level
Your ground is clear, now you need to make it as level as you can. The best way to achieve this is to use a standard garden rake. You should move the rake from the highest point of the ground down to the lowest to start redistributing the soil. As you go, use a bubble level or spirit level to measure and track how close you are to achieving the perfect level. This step is a crucial bit to get right because the flooring for your garden shed works best when the ground is even.
TOP TIP: Want to check your level over a longer distance? Get a long piece of timber and balance the spirit level on it. This clever technique will amplify the dimensions you are measuring and help you work quickly to achieve the evenness you need.
Step four – Kill the weeds
It’s important to treat the ground with weed killer. Nobody wants to find a rogue chickweed among their tools! Once you’ve got to work with the weed killer, cover the ground with weed suppressing fabric (like terram weedguard) and you are good to go.
Step five – Floorbox it
Take the ground reinforcement system (Geogrid standard, Geogrid Premium or Durapath) you have purchased from Floorbox and click together the 500mm x 500mm sections. Abide by the golden rule of measure, measure, measure, and check the dimensions you’ve selected. Put the grid on the shed local and add 10mm of stone to fill it. We recommend that you allow one standard 20kg bag of stone for each half metre of flooring. Check the levels and adjust it if you need to – the stone can act as a self-leveller so use it according.
Step six – Get yourself a beer
Congratulations rock star, you’ve just build yourself the ultimate floor base for your shed. You’ve chosen the right product to ensure that your garden shed will stand firm, and last longer thanks to the resilient grounding you’ve given it. All you need now is a beer and a pat on the back!
