Setting out blockwork from foundation

[Lee Edwards]

Can’t see the need for the 100mm of concrete

Thanks for replying. I thought it was the standard way to cast a slab for a floor?

On the context of a garden room, I’d be unconcerned about skipping it and just putting the insulation on the dpm on the well compacted base and liquid screeding it

If you’ve already dug out for the level, crack on; it’s not a huge expense of concrete, it’s just work shovelling 3 tons of it around. Installing a liquid screed is much more a painless exercise but remember to put a membrane on top of your insulation to contain it

Just noticed in the initial post you talked about block and beam; has that plan changed?

Hi. Thanks for your reply. It is a garden room. That is being built as a house as planning permission was required due to it having a kitchen, bathroom and mezzanine level. I was going to put in a beam and block floor but I have decided I don't want the vents.

With a beam and block floor or concrete, I still.need to figure out which blocks or bricks I need to sit a 150mm wall plate on. That's the part that is confusing me.

Cheers

Ground bearing slab - correct.

I think there was some confusion over B&B floor v's GB slab.
