Re: Low level Deck

@Jason Thanks very much mate

@BIM_Engineer thanks for the advice, much appreciated. As I haven’t done any concreting like this before can I go one further and ask the approx depth and width of the pad? Also, the positioning of this particular stump as you can see from the pic will be where the pool used to be until recently. The soul was compacted but I’m wondering if a deeper hole/concrete will be needed for the bearer support pad as soil may not be as firm due to only recently being put in?

Also, what is the best concrete to use as the pad?

sorry, hopefully that all makes sense

@Johnny

Notes to pad footings sketch
250-300 Diam Depth generally
Those brackets connections can be offset to the bearers
The soil needs to be compact beneath the footings or dug into natural soil
..dig the footings a little deeper
Get the ready mixed bags of concrete...just add water and mix

 So this is where I’m at on the deck. Im just wondering if having this as the last bearer is ok, and let the joists overhang by approx 500mm? TIA

Thanks for the photo
Place the bearer roughly in the same location as it was previously
from the end.( Cantilever Should be less than 10% of the back span)
Bolt( 2-M12 /joist) the extension joists over the bearer.hth

Re: Low level Deck

@BIM_Engineer Thanks for that mate.

Another problem I’ve just encountered after digging a deep hole for one of the stumps is water slowly pooling in bottom of the hole, about 100 deep. I scoop it out but it refills.

I think this is due to the very soft foundation/soil right the way down as this is where our inground pool used to be a few months ago.

ive had to dig down pretty deep, approx 800, to hit relatively solid earth.

@Johhny
When you filled in the pool hole did you compact the soil?
If not then excavate deeper to firmer soil
Thanks for the update

Re: Low level Deck

Hi @BIM_Engineer Ive done the same set up but with half stirrups and I’m getting some movement in the bearer. I’m guessing when I slot the joists in it will

tighten up but do you think this will be sound?

also my bearers are 90mm high so I have a gap under my stirrups (not sitting on the base) I think the vertical plate is about 110mm? Do you think this will work?

cheers!
