I have had to dig out my old kitchen floor (about 4m x 3m) which consisted of quarry tiles on top then 1" concrete then about 18" of compressed clinker/ash - a lovely job.
To install a suspended timber floor, I already have a honeycomb wall & plate one end and the other end is the outside wall so I can use joist hangers on that side. Because of the span I will need additional support in the middle, so it's either another honeycomb wall or three brick piers (my preference).
The question then is how deep & wide would I need to go for the pad foundation for the piers?
I am also proposing using 2 courses of engineering bricks on each pier so no DPC will be necessary. Is this OK?
Any advice most welcome. Thanks.
