I want to re do the top patio with some new lighter slabs and bed them down on a wet mix of sharp and soft sand, but I was wandering if I could leave the old council type slabs (  heavy  and thick  sods ) where they are as my base. I know these havent been layed on anything apart from the dirty they are sat on already 

do the job properly you lazy sod ;D ;D

This where my problem is.. over the yrs they have beome very uneven but saying that none of them move if you stand on them  :-/ :-/

if they dont move i would leave them down  as long as your not planning on parking the car on them should be ok

Good grief, spelling on the OOF is getting worse !!  :o

It's Laaandun !!   :y

If the existing slabs are not on a stable base and have moved, the new ones will do exactly the same on top of them, surely? :-/

Kevin

its ok turk you get used to his awful spelling once youve read his posts a few times ;D ;D

would be tempted to break the old ones in situ rather than lift them and whack then in to the ground to give firm base. How many slabs are we talking about?

I lifted mine - broke them up first with kango to avoid back problems

why dont you smash them up and use them as hardcore.

better drainage with a more solid base :)

ps i know the slabs you mean.... 75cm x 50cm....... and the weight of a small car!!!  ::) :y

Be careful, by putting slabs on top you may be bringing the level too close to the damp course if the slabs are by the house.

Quote:
If the existing ground is the same level as the damp course you are already in danger of invasion by damp. The general rule is as stated elsewhere that the ground should be 150mm (6") below the damp proof course.
Hope this helps...... :y

Thanks all , that has given me something to think about and by the time I make up my  mind  to what Im doing. It will be too late in the year to do it  ;) ;D ;D ;D
