Just need some help and advice.
I'm planning on putting in a 3m x 3m shed to house a GSO 14" RC with either a mesu 200 mount or a JTW mount.
Anyway, Im going with a slab.
- Slab first or pier first
- How deep to I go with the pier
- How high do I make the pier
- What is a good size diameter for the pier
- How much of a gap do I leave from pier and slab
