Browse Forums Outdoor Living Re: decking depth enquiry 7Aug 10, 2011 11:05 am yes well that is another thing to consider. as the slab is only minimal depth from the rear sliding doors, the last brick coarse and damp coarse is at top of slab. therefore if i install a deck - the top of decking will be above damp coarse and will also be about half way up weep holes.. will this be a problem? the area is fully covered under the main roof. only minimal water enters at the edges of the area Re: decking depth enquiry 8Aug 10, 2011 1:51 pm ok this is how it is: http://i989.photobucket.com/albums/af20/grechy12/IMG_1722.jpg and with a 90x35 next to it: http://i989.photobucket.com/albums/af20/grechy12/IMG_1723.jpg or continue the tiles out from inside: http://i989.photobucket.com/albums/af20/grechy12/IMG_1725.jpg Re: decking depth enquiry 9Aug 10, 2011 3:58 pm Huggy_B mikeg12 awesome thanks for the advice. the spacer idea to raise the battens is a great idea too - ill definitely be incorporating this. would you suggest dynabolt would be the best method of fixing to the slab? are there other options? Personally I would use recessed dynabolts, but you could use spaghetti tube and screws. But dynabolts will give you a very solid fix which would be my preference since you are walking on it. http://img.photobucket.com/albums/v709/wombat01/dynabolt.jpg would using countersunk dynabolts be just as affective ? Re: decking depth enquiry 11Aug 13, 2011 2:34 pm i am in the same situation and am in the process of designing the deck.. got a few questions.. the countersunk dynabolt is good idea but would an 'L' brace to the joist and slab be as effective? also, is the plastic horseshoe spacers called that? "plastic horseshoe spacers". i mean if i go to bunnings and ask for that, would they know what I am talking about? and how strong are they since they essentially be acting as bearers for the joist?

MyHomeoneThread Our Oxford22 Blog Re: decking depth enquiry 12Aug 13, 2011 7:13 pm Hey Draco, Bunning Hoppers has them and they're called, "window packers" or U shape window packers. That's where I got mine from. There is also a builders wedge, I don't think they would have been helpful but fairly similar. Cheap, about $14.00 for a whole box so I got one box of 5mm and one with all different sizes 1.5mm to 10mm. See through boxes with the different colours. I raised mine up a minimum of about 10mm so the first board would sit kind of flush with the top of the step, so the 2 x 5mm worked a treat. But as expected the slab for my alfresco isn't 100% flat so you'll need a mix of sizes. Mine is basically joist on to slab, packers to raise and keep water of the joist, L brackets (There's $6.00 ones and (Pryda) $2.00 ones) dyna bolted to the slab, then 40mm coach screws in to the joist (lucky Bunnies had someone helpful that day as they work really well). So far not looking too bad. Total height of the deck is around 200mm. I think if there's a hurricane, the house will be gone but deck will still be there. Not sure if it's a 100% correct as all advice seems to be about building over dirt then using concrete with stirrups/joists/bearers.

MyHomeoneThread Our Oxford22 Blog Hi, as per the subject. Does anyone have any recommendations for the best value decking oil (Bunning is close to where I live) for a treated pine deck?
