we are looking to deck our alfresco area, its a concrete slab with a 70mm step down - not much I know, what’s the best way to go about it with such a small step down to work with ?
does anyone also have a great program to work out deck plan / spacing etc ?
Hi @Tracey113 ,
Welcome to Workshop. We look forward to seeing how this project progresses and trust that you'll get plenty of helpful information and advice from our members. Feel free to post whenever you need a hand.
I also welcome any feedback about how we might improve Workshop for you. Just let me know.
Mc Donald Jones Homes? I just built a deck over our concrete slab with "70mm" setdown. The main sliding door was even less than 70mm setdown, other bedroom door was more than 70mm, had plenty of issues getting it done, wall to the right was not square either.
70x35mm Pine subframe secured to concrete with screws / plugs. Levelled using window packers
5mm spacing, wanted 5mm minimum which worked out good as the board widths over the width of the deck worked out full boards the whole way across. Painted the subframe black to avoid the "see through" effect.
Hi, Just a thought. Did you put down a moisture protection layer between the frame and the decking boards?
If you do, then this normally comes in back, which means you would not have seen through the decking boards.
@asarson yes ours is MJH house - in hindsight wish we realised that the set down was only 70mm. Do you mind sharing a pic of what you did around the pillars and the edges / sides ??
Well as I am building a built in bbq the outside edge of the deck is still unfinished however I plan to picture frame finish the edges. It’s a little difficult since we are using 140mm boards and I can’t get to a full board around the pillars without cutting one down.. I plan to just check in full boards around the corners of the pillars rather than cut down full lengths. Hope that makes sense.. the inner wall was out of square also so we had to taper one end down.
