Hi Team,
I am in the process of building a deck in my alfresco.
i would like to clarify, is it ok for me to build it this way?
the spacing in the picture is not correct. i was thinking 400 MM between each wood and then the deck boards go on top of it?
will this work? or should the base frame be above the ground? I.e not touching the floor?
Thanks a lot
Hi @shawnvaz,
90 x 35mm is OK if you've already purchased it. You don't need to have two Dynabolts; one should be sufficient. You can use Ankascrews instead of Dynabolts, but both shouldn't be placed within 100mm of the edge of the slab. Dynabolts will only crack a slab towards the edge if they are placed too close. They will be acceptable to use everywhere else.

Thanks for the support.
I have laid out the frame. have not screwed it in as yet
just wanted to check. will this work?
im doing a picture frame, so i have left around 25mm from the wall so the deck board can overhang. is this ok?
the height difference is 20 mm.
could you please tell me what spacers i need to use and also which bracket will suite?
the side that falls away form the home is at a height difference of 70mm+20mm. so a total of 90mm
Also the side which i have placed the wood frame-spacer-spacer and frame, which piece should i support with the bracket? should i support both pieces or just the one?
what screws can i use for the 90*35 frame to build it together?
on the top end. i might not be able to use screws to attach the frame, what is my alternative?
Thanks
Shawn
Hi @shawnvaz,
The layout you have looks like it will work. Can I ask why you're changing the spacing as you move along the deck? You usually keep a consistent 450mm or equally divisible spacing across the whole deck. Having unequally spaced lines of screws would look a bit odd.
A 25mm overhang of that last board is acceptable. You don't need a spacer to accommodate for the 20mm height difference. You simply fit the brackets to the timber at the correct height as per my previous images. A larger bracket can be used on the section on the side that falls away.
If all the frame timbers are connected together, you can support either of them with a bracket or both of them if you wish.
Zenith 14G x 100mm Galvanised Type 17 Batten Bugle Head Timber Screws would be suitable for joining your frame together. If you can't screw them together, Pryda Joist Hanger Suits 35 x 90mm could assist.
Please let me know if you have any questions.

The Ekodeck 100m Pack Quickfix Concealed Kit is a fantastic seamless solution and allows you more flexibility as to where you position your joists. Just don't space the joists much further apart than 550-600mm as you start to end up with spongey deck boards.
I believe @EricL recommended a "Bolt and Nut Galvanized in conjunction with Washer Galvanized", and I'd concur. The Zenith M6 x 50mm Hot Dipped Galvanised Cup Head Bolts And Nuts would be suitable for your 35mm thick timber. Either cup head or hex head would be fine. The cup head bolt has a square section under it that will bite into the timber and stop it spinning when you do the nut up on the bracket side, so the head side goes onto the timber.

Hi @shawnvaz,
My mistake. It looks like I've provided the incorrect link above. The Zenith M12 x 50mm Hot Dipped Galvanised Hex Head Bolts And Nuts would suit a bracket with M12 holes. You could drop it down to a Zenith M10 x 50mm Hot Dipped Galvanised Hex Head Bolts And Nuts, but I wouldn't suggest less than that.
For bolting the bracket to the concrete, I'd recommend the Ramset 12 x 70mm Galvanised DynaBolt Plus Hex Nut Bolt. Once again, you could drop that down to a Ramset 10 x 75mm Galvanised DynaBolt Hex Nut Bolt, but I wouldn't go any less than that.

Hello @shawnvaz
If you're thinking about how the picture frame is attached to your frame, I suggest having a look at the Ekodeck How-to-videos. There you'll see how the leading edge of your deck and fascia are mounted onto your frame. To get that clean look, the panels are attached using angle brackets in combination with the Ekodeck Quickfix System.
If you need further assistance, please let us know.
