decking over paving slabs

Postby chrispsykes » Mon Mar 08, 2010 2:25 pm

Hi everyone, I’m new to this forum and I’m obviously after some advice! I’ve got a small patio garden which looks terrible, really old paving slabs which are all over the place. I’d really like to do decking over the top. I’ve done quite a lot of research on this and I think I can do it. There’s one thing that worries me though- (not sure how to word this!....)what’s least amount of height needed? It’s just that I’m worried about being able to open my back door! The gap between the bottom of the door and the top of the paving slab is about 15cm- do you think I’ve got enough space? Or if not, would I be able to take all the slabs up, and deck over whatever’s underneath? Thanks a lot for any help you can offer :) . Chris

Simply Build It

Set treated bearers (75x50) on mortar dabs on the paving slabs to give a level base and fit the decking on this. Don't use a continuous bed of mortar or you will trap rainwater.

Stoneyboy accurate and to the point as usual. Great stuff!
