Hi all

At the back of our garden I am planning to build a concrete pad as a base
for a garden shed.

The ground rises a bit towards the back of the garden and we have had to
excavate in order to level the ground.

Consequesntly the concrete pad will need a wall on 3 sides to support the
earth behind it if you see what I mean.

The pad itselef will be about 8'by 6' which includes about a foot extra
width for the small wall on the 3 sides (shed is 7' x 5'). The wall willl
only be 4 bricks high.

To support the shed, I have read that no hardcore foundation is necessary
and the concrete should be about 3 inches thick. However I would think that
the wall will need a bit more support.

My qurestions are these; How should I approach this? Should I dig down a bit
further 1 foot from the edge on the 3 sides and put extra concrete in there
or will I be able to get away with 3 inches all over. Will I need any
expansion joints in the pad as well. If I should put some in where should I
put them.

This is my first attempt at doing this sort of thing and am quite looking
forward to the challenge.

TIA
