Our sheds do come with a floor, you might want to think about the optional extra of insulation when choosing your flooring option. All our sheds come with floor joists on the underside of the floor to lift the shed off the ground – but you may still need a base.
The type of floor you require should be determined by what you wish to store. The heavier the equipment, the thicker the floor required.
OSB (Oriented strand board) floors are most common in cheaper sheds. They are usually reliable but may sag or soften if exposed to too much moisture.
Timber boards or tongue and groove flooring will be stronger and offer greater protection against ground moisture.
As a general rule of thumb for wooden floors, 12mm tongue and groove and thicker is considered very high-quality shed flooring.
Also look for pressure treated floor bearers. Even an OSB floor may be supported by these rot-resistant supports, helping to extend the life of the shed and the floor.
Your garden shed needs to be built on a secure, level and adequate sized foundation. We like most retailers do not offer a base, and this will need to be in place before we can install the shed. Bases are typically built from concrete, paving slabs or timber bearers, and a correctly assembled base will prolong the life of your garden building.
Types of shed bases All sheds will need to be sat on a sturdy, level surface otherwise the building will shift and misalign. If you want to position your shed on grass it will need a shed base. Shed bases typically come in metal or plastic. Or you’ll find sheds that have metal frames which can be filled with concrete or covered to create a floor and a base in one.
There are four main types of shed base: poured concrete, concrete slabs, wooden bases or plastic grid bases. If you have an existing shed base, you will need to check that it is still solid, level and suitable for your new shed.
If you require a new shed base, there are two methods to consider. Both require a levelling and firming out of the grassed or earth area.
The first option is a hardstanding base, such as poured concrete or slabs. You can engage a tradesperson to do this.
The other option is a base which lies on top of the ground and a sheet of membrane. This can be a wooden base or a plastic grid base. This is an easier DIY option but still requires proper ground preparation.
