Hello
We had a blockwork outbuilding built last year (about 4m x 3.5m). I've previously asked for advice on water ingress but another thought has come to mind on the construction of the shed. I can't say for sure but I think it's built as follows (pics attached):
- Hardcore (not sure how deep or what type)
- Concrete slab (not sure how deep or what type
- 4 courses of blue engineering bricks
- Medium density blocks
I got concerned when the builder cut out the overhang of the concrete base as he said that might be why it was leaking. Another builder says there should be a 6 inch overhang for foundations, my builder says that is only for "actually for foundations when building an extension or house".
Has the shed got an adequate base?
Many thanks
Paul.
