SoCal *Splash* Pool

I see the vertical rebar now.

If they do a good job with the concrete work, take the forms off at the right time, and give you good sharp edges then that extra 3” will never be known. Anyway to get you your 12” width can create more problems you don’t need.

I agree. Def not worth chasing after the 12" width. I am talking myself into loving square-looking coping and lots of joint lines (15 1/2" x 24 looks more square than rectangle to me.)
Did the pics answer this concern: I am more concerned about how the cantilevered coping will kept isolated with an expansion joint from the bond beam and pool structure.
Also, you're not concerned with that 6" of loose dirt the concrete's being poured on?

Anything under the forms should be well compacted. My guess is he feels most is on the bond beam amd that's good support. The issue I see is first I dont see amy bonding wire. In a cantilever deck the rebar sticking up shouldnt be there. Ideally the bond beam would be somewhat flat amd rebar chairs would be holding up wire tied rebar into the lower half of the form. Rebar should be placed at the 2/3rds breakline, so 33% up off the bottom. If the deck amd coping were one piece then tyvek or some form of release should be under the form to break the bond. BUT in this case of just coping it's fine as is, no different than mortaring precast coping in place. It's an unusual way of forming coping, but its not their first time I bet, as long as they pull the supports and finish it right it should be ok

As Jimmy points out you are not getting cantilevered coping. You are getting 15" wide poured coping tied into your bond beam. Which is ok.

What are you putting for decking next to the coping? There should be an expansion joint between the poured coping and whatever decking is put down.

Thank you. Sorry, I am confused. You are talking a lot about a deck which this isn't, so it's confusing me. When you say, "in a cantilever deck the rebar sticking up shouldn't be there," does this apply to my cantilever coping as well? Also, is bonding wire the copper wire coming out of the bond beam at intervals around the pool, which we do have, or something else? And is this your only issue with what you see? Thank you for clarifying!

Gosh, I didn't get that from Jimmy's post. In fact, it is cantilevered coping, that is, it is overhanging into the pool 1 - 1 1/2" - isn't that considered cantilever coping? OR are you saying it's not cantilever because "true" cantilever does not tie into the bond beam? Sorry for my confusion!

It is not cantilevered construction. It is just coping with a bit of an overhang.

With true cantilevelred deck you do not need or have an expansion joint between the coping and deck. That gives cleaner lines. With your construction you need it.

With a true cantilevered constuction you do NOT tie any portion of the coping to the bond beam. The two structures need to be able to move independently to prevent cracking.

You have coping with an overhang.

Post pics of the copper wire you have coming out of the bond beam.

That makes sense. Thank you for clarifying. This is quite a ride my PB is taking me on! IMO, they shouldn't be calling it "cantilevered" !? I know it is not constructed like the one in the drawing you sent. Thanks again, I really appreciate it!

 

[Girija]

I'll go take some shots of the wire now . . . thanks!

 

[Girija]

Post pics of the copper wire you have coming out of the bond beam.

Okay, here's a pic. The wire comes out of the side of the shotcrete shell (under the dirt). I found a total of 5 around the pool (could not locate one on the deep end).

 

[ajw22]

The rebar in the forms should be connected to those wires at some points.

 

[jimmythegreek]

Anything containing rebar around the pool including the coping and possibly the deck if that's the direction should have the bond wire tied in 4 or more spots, sounds like that is the case.
Sorry to confuse you, was explaining it both ways because you said cantilever but as Allen pointed out that's technically not what u have. All coping is overhung, so its pour in place coping technically as he pointed out. Always better to ask than assume as they say......feel free to fire away with any questions

Thanks! I appreciate your help. So just to clarify, the bond wire should be tied around the coping rebar in at least 4 places around the pool (I'm assuming on each side?) and also on the deck rebar once it's placed?(yes, that's the direction we're going) . . .

Bond wire needs to be electrically connected to the pool rebar, coping rebar, and deck rebar and continue to connect to the pool equipment.

 

[Girija]

Thank you so much Allen!

 

[jimmythegreek]

Allen is correct like usual! Good practice is 4 spots spaced out somewhat evenly

Glad your getting all this solved! A pool build is so stressful. How's the next step going?

Hi Sollace! I wish I could say how the next step is going, but nothing is happening here. We got a timeline from the PB for the remainder of the work, but it showed tile work starting today or tomorrow, yet no word of that actually happening yet. We also decided to remove our entire existing patio d/t the pool being higher that it should have been (PB is paying the lion's share of the demo and pour). If we didn't remove the whole thing, the PB was going to take out only half to get an indiscernible slope from the pool, but it would have looked pretty hoaky to have half old patio and half new. That demo is supposed to begin Thursday, tho it was originally supposed to start last week.

 

[Sollace]

We had delays, too -- Thanksgiving and Christmas, especially Christmas to the New Year's. Even now we're waiting on a part for our pool equipment. That TX freeze really set a lot of pools back, too. More pool owners buying equipment, less supply in stock. So frustrating.

Things will get better!
