There are 3 options for bases:

1) Concretes slabs on a mortar bed – which are adequate in most cases but if you put concrete slabs on ground under which run tree roots or other vegetation then the slabs, over time, will start to uplift and can also, over time, start sinking into the ground.

2) A solid concrete base (which will include steel reinforcement within the mix) no less than 100mm deep is ideal.

3) A timber beam base – this is necessary in rare cases where the building is on a steep slope or to be built near trees with tree preservation orders on them.

The base should always be a minimum of 50mm out of the ground to prevent surface water or puddles affecting your building i.e. rotting it.

The size of the base needs to be the metric size of your building. For example, if you order a 8 x 10 shed, the metric size is 2.4 x 3.0 metres and this should be the size of the base. If the base is not built to the metric size then you will see the base around the building which is unsightly.

Bases for larger buildings and in particular garages need to be built to exact dimensions and drawings should be obtained from us before the base is laid.

Always get your garden building base laid by a professional. We supply a base service if you should require it.
