I am currently planning out the deck for our new home which is getting built. The build was a little more expensive with all the extras we put in and wanted to try and save some money by doing the work on the deck myself. Plus I can say I built something on my home. My issue with the deck is that it is an L type shape as it has been extended slightly.
The deck is going over concrete and has a slight fall in line with guidelines. I have chosen to use 90 x 45 joists and am open to recommendations as it is my first deck.
I have done some research and like the klevaklip product so any input from someone who has used these before would be appreciated. Also if there are any alternate options am open to suggestions.
I am thinking to do some mitre cuts to for the edges for a 'frame' to the boards
and want to understand if this is my first boards on the house etc will I need to put a double joist in place or are these not going to flex if I just use the normal joist spacing?
Thanks in advance
You'll most likely need to have a double joist. On one side of the deck, you can extend the joists so you have something to nail the mitred framing boards onto, but on the other, an additional 90 x 45mm piece of timber will be needed. This is because there won't be enough width to the 45mm timber to secure the end of the deck boards and the framing board.
Just to let you know I've made contact with Klevaklip and their products are available through our special order desks instore. If you were after the joist support system we can certainly order them for you. I believe @bruce93 has some experience with Klevaklip so he might be able to assist with any questions you have.
Please let me know if you need further assistance or had questions.
Thanks so much for the information. I was thinking along the lines that you have mentioned I just wanted to ensure that I was doing the right thing. Really appreciate the help and suggestions.
Thanks @bruce93 really appreciate you reaching out. I do have a question around the ease of use for klevaklip products. My biggest concern is trying to make sure it is level but I understand that the klevaklip system adjusts easily. Any advice with layout of joists?
Thanks in advance.
The levelling is the most time consuming part of the whole process. But then again if you take your time and get it right then the laying the boards is the easy part.
In regards to layout of the joists. I was told by Demak who I sourced the joist supports from that the easiest way to do it is lay your joists 90x45mm treated pine on the floor. Make sure they are spaced 450mm centres as recommended. And then with a builders pencil trace the side of each joist onto the concrete. Then remove the joists. The advantage of doing this is when you lay the klevaklip down to secure it to the slab it is actually marked where the joist will be with 2 grooves.
I've circled the image where the grooves are.
I hope this makes sense. I also would recommend using all galvanised fixings being outside for the hardware associated to the Joist Support.
