Deck without screwing into facade?

[King_al]

Hi,

I plan to start my deck project this weekend and have organized most of it. Initially, I thought about screwing the inner ledger beam to the facade, but now I'm hesitating. Would it work just as well to lay it against the facade with a small gap? Propping it up with joists? It will be about 25cm high.

Groundwork hasn't started yet. I will level it first.

I dug X number of adjustable piers that the entire deck stands on, the nearest row of piers is about 0.6 m from the house foundation.

Okay, that's about what I had in mind too. But I'm planning to keep around 50cm overhang. But how do you manage near the facade? Does the end of the deck sit against the facade or do you have a gap? Possibly a picture to share?

With three houses and as many patios, I have never screwed a support beam or joist into the foundation or facade. Pillar or paving stone/Lecablock closest to the facade, depending on ground conditions. Then just build on.

I'm using a gap of 5-7cm so that leaves and other debris don't get stuck and add moisture to the facade. I'm attaching two pictures from a project last year that resemble your conditions. I recommend adjustable post bases on slabs like the ones you have (available at places like Biltema for a little over 50). Fast and stable assuming correct center-to-center measurements.

Keep a distance of 5-7cm so that leaves and other debris don't accumulate and add moisture against the facade. I'm attaching two pictures from one of last year's projects that resemble your conditions. I highly recommend adjustable post shoes on slabs like the ones you have (available at, for example, Biltema for just over 50). Quick and stable, provided the correct center-to-center measurements.

Thanks for the tip! So no need to dig down foundation piers either? I thought it was a requirement if you don't attach to the facade? Maybe there's no risk of the deck shifting over time? Initially, I planned to dig down every other pier and use paving stones in between, but maybe that's overkill?

Thanks for the tip! So digging down foundation posts isn't necessary either? I thought it was a requirement if you don't attach it to the facade? Maybe there's no risk of the deck sliding over time? Initially, I thought of digging down every other foundation post and alternating with paving stones, but maybe that's excessive?

It might also depend on which part of the country the deck will be located in.

I placed mine on 35*35 tiles that were leveled. Then the beams were placed on top, with sill paper in between. You seem to have both tiles and a pretty good base already.

Yes, I should have used paving stones... tried to dig down ground posts today... damn, what a job! Hardly straight or good, but I got down 6 ground posts. Will use paving stones for the remaining part!! It will be a shorts hybrid.

Has there been an old deck there? It looks like the paneling ends too high up. But maybe not a problem if a new deck provides cover.

Yes, there was a small deck that was sagging and seemed to have a life of its own. Hence I thought of making it "a bit" better.. I removed a plank that was running along the facade at the same time.
