No worries on the questions! This place is where I did all my learning during the build process and it saved me a couple thousand dollars on unneeded equipment and kept me from looking like a goober when I was asking the builder questions through the construction.
In one of the pictures above you can see the brackets without all the lid covers on. I will try to get a better picture this weekend. I know this type of lid is not for everyone, I spent some extra, excessive bucks to get it. My wishes were to have a clean, simple looking pool. I do not care for the plastic or aluminium lids I had seen on other pools. Also with those lids, a portion of the cover fabric is always visible when the cover is fully retracted, drives me crazy!
The way this lid ending up being, only the silver edge pole of the cover is visible as it snugs up to the edge of the concrete lid. There is another option of raising up the deck higher and the lids wider and getting the cover edge pole to disappear completely, I wasn't comfortable with the design and the look to make that happen so I settled for the middle of the road option.
The brackets are some pretty serious stainless steel pieces. I imagine they are pricey to get. The brackets are 18"-20" long and are adjustable to level them up and down even after they are anchored into the vault box wall.
Stable? It's not concrete decking, that's for sure. You can tell they are squares of concrete suspended on brackets. My builder did a great job of getting tight seams and leveling the whole lid. Builder asked/recommended for us to not make it habit to have the kids launching off of the lid, I can see over time the downward pressure causing issues. The way my pool is oriented all of the running and jumping comes off of the long side, the lid side is close to the wall and is mostly just a walk around. I left room to put a diving board that wouldn't interfere with the lid if I want to in the future.
We don't walk on the lid much, I stand on it if I am brushing walls, no concerns. If new kids come over and are jumping off it a quick reminder keeps them off.
I can see why builders are not keen on the concrete lids. Things can go wrong or end users might be hard on them. It is something I wanted and my builder did a good job of giving me the pro's and cons. Builder poured us two extra lid cover sections in case anything happens to one of them in the future they will match color and fit.
Ease of access is given up for the look, I like the way it looks and I am comfortable with the extra work.
