Hi I am to lay base for greenhouse 14ft x 8ft, client now would like me to lay 3ft x 2ft slabs down the middle flush with surface. my thoughts are it will sink into the concrete, any suggestions for best way to stop this happening? and is it realist to do this.

Do you mean the face of the flag flush with the surface of the concrete base?
I cant think why your client would want that.

Yes, he says it will look a better finish than just concrete. A bit of a pain really, can only think of putting some brick set in the concrete under them to support their weight, though it might weaken the finished article.

Client? you're doing this job for money and you don't know how to stop concrete slabs sinking? Is this a wind up?

neil, i see you are in my neck of the woods. Are you sure you've attempted this kind of stuff before? Bricks are a no no. You really need to lay the flags first on a semi dry concrete mix. using your flags as ''screed rails' you can lay wet mix either side. You'll need a contraction joint either side of the flags, or cut one in next day. Good luck and post photos.

^^ as above lay your slabs first then concrete after
TBH he is overcomplicating a greenhouse base
why not do it all on 50mm council greys?

neil i can see stewarts point, these are the things you should know about when pricing a job. It is pure basic stuff really. The fact you were going to corner the flags up on bricks shows a distinct lack of experience. But hopefully with men like stewart ('carbery) you can learn a thing, or two .

Thanks for the vote of confidence Sean. There is still a lot for me to learn about this game but I get really annoyed when 'tradesmen' charge for work when they clearly have no idea what they're doing. One bad experience for the customer and they tar all tradesmen with the same brush.
Neil - follow the advice on here and it's hard to go wrong. If you are charging somebody for this work then I suggest you read everything on
