Stone patio around dek blocks


I will be building a stone patio soon, but I will have 2 dek blocks (that support a small 4'x10' balcony).

My question is how to place the slabs around the dek blocks?

No way would I be counting on just deck blocks to support a roof.
There going to sink and there's no up lift protection.
Should be sitting on real footings with post bases on the bottom.

I am not counting on anything. The Balcony was installed by the builder. The stone patio will be on the ground level and will be 14'x18'. Since the balcony is above the patio, the dek blocks that support the balcony are sitting on an area which is part of the future patio.

My question is how to install the slabs around the dek blocks? Also, since I need to excavate 8" for the patio bed, how close can I excavate to the bek blocks?

May want to post a picture so we can see what your seeing.
This is what a deck block I'm picturing looks like.

You are right - that's what I have





And this is what I have from the builder:



It's in French, but it states 'Techno type metal support' or equvalent.

A Techno Pieux is a helical pile. Doesn't look like your builder follows prints.

Never going to work the way it is, never should have passed inspection that way.
If this is new constrution I'd get his lazy butt back there and do it right.
And no a post can not just sit in a slab, it needs a real footing, then you build the patio around it.
That has to be the smallest slider I've ever seen.

Using temporary supports for the deck....
Dig under the post a 12" inch diameter hole the depth of your frost line.
Pour a concrete footer level with the existing ground.
Once the concrete has cured for 24 hrs. install some post anchors.
Re install the post, and remove the temporary braces.

The stone installation will be easy and self explanatory.

If they messed up this building 101 item it would have me wondering about how that ledger was attached, how close it is to the threshold of the door, and how it all was flashed.

To the op, if you look at your blueprint, it APPEARS that the builder forgot to add the portion of that support delineated with the dashed lines....indication an area below the ground level. Hopefully he put in the parts of the foundation shown as below grade! Just kidding about the latter...but you cannot dig anywhere close to those dek blocks...and I wouldn't want to be standing under that deck when a good strong wind comes up. Best suggestion so far is from joe45 which is a standard approach to dealing with rotten deck supports. Ron

thanks guys,

I talked to the builder, and they said that this is the only way to get it done since the area is quite rocky, so they cannot drill.

Is this BS? What should I do to counter them?

thanks

Never used a helical pile myself, but I understand that it is true that they are a pain when you hit rocks. But you don't get to ignore engineering specifications just because its going to be more work. He only had two to put in, so is he saying he tried to put them in and hit big rocks, or didn't even bother to try ? (doesn't really matter anyways I suppose, like I said, you don't get to ignore engineering specs just because its going to be more work, but I smell BS - bet he didn't even try to install the helical piles) If he can't put in in the helical pile, then I suppose he has to dig hole to below the frost line like Ron suggested. You didn't post where you are, but just about anyplace would have had an inspection, and just about anyplace that would have failed. If township did inspect, call the chief (not the inspector who will now just try to cover his ass) and tell him what was on the print, and what you have, and ask if that is OK.

I am im Quebec, where usually rules are much stricter than elsewhere
They did not even try becuase they know it's a rocky area. The frost line I think is 5 feet. I have contacted the city and wating for a call back. I could do the sonotube approach myself, but if I did that, I might as well enlarge it it make it more solid. Just don't have the time to deal with nor the extra $$$ to pay someone else.

I think the deck was built after the house passed inspection. The answer from the builder was that they've done the whole project like this due to the rocky areaa.

Without regard for how the builder did the entire project, I would not want to be on or under that deck when the strong winds of winter hit because while Dek blocks DO provide a footing for downward pressure, they do nothing for uplift nor do they do anything for lateral support since the posts sit on them rather than being attached to something solid in the ground. Let us know what the locals say. Ron

If this new constrution those joist should have have been in the plans so no post would have been needed.
