Attaching rebar in holes

[Dr Jumping Jack]

A bit late for tips now, but if you have weak studs and heavy loads, one option is to lay a load of gravel on the ground, smooth it out, and place pressure-treated studs on the gravel.

The two concrete posts are one meter into the ground and 30cm above the surface. It likely requires some effort to get them out of there.

Test-drilled a post with a 12mm bit yesterday and got 20cm down with a hammer drill. Then it went slowly. Thoughts of Jula's rotary hammer from Meec, costing 600 kronor, came up. I read that it drills through concrete like butter. But who knows?

It's not enough to drill a few holes and stick some iron in. For the reinforcement to be effective, it must go through the entire post. I don't know how tall they are, but I guess it's more than a few decimeters? If you're going to drill half a meter to a meter, it's probably easier to make a new post.

get a lot of new concrete for 600
I wouldn't bother with drilling.
Fresher concrete is tougher to drill into as well.

I already have the drill. But what you said about lifting the foundation block straight up, I might actually manage it. The paper tube should make for low resistance through the ground. It sounds worth trying!

the time and price of a 1 M drill, I would rather make a new foundation block.
15 cm width should just be able to lift straight up and in with new concrete.

 

[Hallerudsbo]

Yes, it can be done.
Otherwise, if you have a swing set for the kids or something similar, there is rope and pulley or hang onto the rope to help lift it up.

Personally, I would have replaced the beam and redone it.
But otherwise, let it be without.

With 12 blocks on 9 squares, I wouldn't even consider picking up two because they're missing reinforcement. I don't even know if I would consider reinforcement.
