Block and beam

[Diggy]

Just to mention for anyone who might have a look at the block and beam job that was offered , don't forget that they have a camber on them.
This can be 1:300 that I've seen mentioned - or up to 10mm on a 3M T beam & 15mm on a 4.5M T beam , I only mention it in case someone didn't know and the job was mentioned as being tightish to the DPC.

Not trying to put anyone off , just saying.

Cheers

Who in the right mind would tile direct to them.. :lol:

Well I think he mentioned it might need some work hence my post given the limited height he was talking about.

You cannot tile directly to a beam and block floor.... Too much bounce, too many joints, doomed

Well, that's why I posted, for professional suggestions. What would you suggest in preparation then in order to take the bounce out, or to minimise it's effect?

I remember from 40 years ago they screeded them....

You need to screed it first, as it is out doors you will need a cement sand screed or you could use a flowing concrete. You would need depth of about 50mm reinforced with fibres and jointed at 2m by 2m intervals (depth x40)
