How to build base for Absco garden shed?

[Bondy2]

Absco Garden shed kit. Do I have to set it on a concrete base? Would a gravel base or AstroTurf do? In which case, how do I anchor it?

Hello @Bondy2 

Absco sheds are very particular about the anchoring of their shed kits. According to the Absco website:

Anchoring your garden shed to a concrete slab is a requirement for Absco’s lifetime warranty. Due to the length of the required anchors, these are unable to securely attach to other bases, without movement, such as pavers. Anchoring your shed to a concrete slab provides extra stability to meet engineering standards and delivers security that it may not have had otherwise. We strongly recommend you decide on your shed size before continuing with your slab, as once poured there is little flexibility in the size.

I'm sorry, but turf and gravel are not ideal surfaces as there is nothing to anchor onto. Should there be a thunderstorm or strong gust of wind it will carry and topple the shed and could possibly cause injury to yourself and those around you. 

Pouring a small or midsized slab is definitely achievable. But should you go for larger slabs, I suggest engaging the services of a professional.

Here is a handy step-by-step guide: How to pour a concrete slab by @tom_builds.

Once you have your slab built, I also recommend checking out the stores Shed Assembly Service. Please double check with the special orders desk as not all sheds can be assembled as part of this service.

If you need further assistance, please let us know.
