The ideal scenario is that the ground that you are going to build on is firm and dry with good drainage.
They provide a solid flat base upon which to build or set a shed and evenly support the floor.
The big draw card for piers is that the shed is above the ground so it is kept dry at all times.
Add 10 contingency and round up small decimals so in this example round up to 0 70 cubic metres.
It can however take a little time to set up the piers properly.
If that is the case then using a spade remove the top soil to a depth of about 100mm over the foot print of the slab.
This helps spread the load and adds longevity to the foundation.
Building a shed foundation can take a long time and it can be difficult to make sure that the foundation is level all throughout the project but a few simple tricks can help.
A foundation of pavers sits on leveled exposed ground or a sand base.
So for a 100mm deep concrete base that s 3m x 2m you ll need 0 10m x 3m x 2m 0 60 cubic metres.
