I am currently working on a decking on our alfresco. Much similar to how Stormy did it, joist sitting on the concrete. Fortunately, I haven't progressed that far. I get your point that joists should be elevated. What can I use to achieve this? Can you please give me an idea, say if I go to bunnings, of what to look for? An easy fix that I can think of is have joists sit on paver bricks then use an angle bracet to fasten the joist to the concrete slab. I'll be in trouble though if these paver bricks either break or move. What are concrete packers? Another point is that there will be spaces between planks, where food and other little rubbish can fall through (I am going for 3mm). Has anyone come up with a solution for this, eg putting compound of some sort on the gap (just like a sealant)? Any help would be greatly appreciated.

Also makes it really easy to get it all level regardless of the condition of your slab. http://camdenbuild.blogspot.com.au/ by invite only please pm me Re: Can u deck over existing concrete slab? 37Mar 10, 2015 9:03 pm Those diy decks look great, and that kleva klip looks like a great idea. Part of our building package has a deck on the alfresco, but we are thinking we would like something in the front entrance way very similar so will be watching this thread with interest. Re: Can u deck over existing concrete slab? 38Mar 11, 2015 8:32 am Thanks Robbie and Plucka. That Klevaklip looks like a solution - clever! Hope Bunnings or Masters have them. Re: Can u deck over existing concrete slab? 39Feb 08, 2019 12:30 pm We want to deck over our alfresco slab which is relatively flat but also extend out over a concrete path which has a small slope to allow water run off. Is it possible to deck this and keep it all level?
