Hi,

Just about to start adeckingproject in my garden. I haven't built
deckingbefore, but I have spent some time planning my build out so
I'm pretty much set. One question though. I've built good strong
fences before and instead of concreting in the fence posts I have
used metal spikes. I am wondering if something like this

support the raiseddecking
instead of concreting in?

No. First of all they are unecessary, secondly they can twist if
they hit stoney ground, and thirdly they could well sink.

I don't know if your deck is freestanding or attached to a
building, but in either case the only reason to concrete in posts
is to keep the deck 'square'. If you don't achieve that, then
boarding it will be a big problem.

The support for the joists is achieved either by a cross beam or by
using padstones to support them.

How 'raised' is yourdecking?

I've built sh*t loads of decks. Happy to give any advise I can.

Hi Dave sorry for delay (been away with no access to computer). The
deckingI have planned is raised about 4 ft. It's about 9 x 8 ft.
Two lengths of thedeckingwill be secured to the house exterior down
one length and the conservatory exterior down another length (all
above the DPC at roughly interior floor level). The joists at those
ends will hang off of the 2 x 4 screwed to the walls.

4 x 2 will need support every 6' of span to avoid bounce (assuming
joists at 18" spacing) If you went up to 6 x 2 they can go 10'
without support. More timber granted, but less support.

Cool, if I use 6 x 2 then I can run each non wall lengths without
additional support other than a 3 x 3 post in the remaining corner?

Yup. *A 6 x 2 C16 will span 2.95m at 450mm centres.

Sorry you lost me on the 450mm centres bit, what's that, I'm assumig
spacing between joists?
