Concrete Wall

[coopns]

I would like to attach a concrete wall with rocks to an existing concrete wall.

I made a form, poured Type S concrete on hardibacker and spaced out rocks.
I didn't use any wire mesh. The form is about 2 inches thick.

Should I use some wire mesh on back? Thoughts on how to attach it to concrete...Tap Con's and concrete or landscaping adhesive?

I have it resting against the wall I want to cover/attach it to.

Is that the full size of it? Meaning you only need to attach the one piece you made?

 

[coopns]

Yes, I thought I would start with that (see if it worked) then try another section.

I'd use some tapcon screws and then hide with paint. Have to see how well one does in the concrete though as far as falling apart. Maybe drill through a rock and then the screws?

Should I add a layer of wire mesh on the backside embedded with concrete?

What's wrong with the original wall. Looks pretty nice in the photos. Sometimes you're better off with what you have.

I would use some ridged insulation or poly foam roll like this. As long as it is not needed for added strength.

Why the foam...to allow movement?

Hefty concrete anchor bolts should hold it. Still a pain the ****, I imagine.

Why didn't you just mortar and grout the stone to the brick after a good powerwash? It would be permanent I suppose.

Kinda interesting project though!

I was chicken to try that...I got the rocks from the beach which are only 1 or 2 inches thick. I saw Ardex is the product to use but expensive...so I was just DIY'ing on a budget that agrees with the wife.

Tapcons embedded in the front veneer joints and construction adhesive. Make sure you like it because this method means it's permanent.

I agree with Danno. I hope you used some adhesive mixed in with your mortar.

I think I would have put this right on the wall. I would have drilled some holes for rebar and bent it 90 degrees for support coming out of the wall and then fabricated the wall. I don't think the mesh will do anything to help now that the wall is poured.

I guess the other option is drill some holes at the bottom and put rebar in them and set the wall on there. My concern with using lag screws or anything similar to fasten it now is the weight and the likelihood your stone wall will crack. I also wouldn't trust any adhesive, especially with concrete.
