question on pool deck

[cybernation]

I must have made a mistake in my measurements.. It is indeed 75000 liters verified by pool store

The issue with the cracks in the concrete is the coping has snapped off and there's a 1" gap between coping and concrete. I thought about putting concrete in the gap but I'm not sure of that's a wise idea.

Ive also thought about taking out the whole piece of concrete and putting a new one in. I'm not sure on the difficulty level of this solution. (have a bad back)

Pool store 'verified' volume is almost always high.

Yeah I know the pool store information can be highly inaccurate but I've kinda verified the amount due to the rise of tc and decrease of ph when adding a specific amount of chlorine / muriatic acid.

Thanks though!

Hello here's all the pics of my problem

Any advice would be nice

Pool store told me I should fix it this year, and the cost is about 2600 for 4 corners or 4600 for all concrete pads including removal.
This pool store has a rep of telling you a low price then jacking it up while doing the work.

Could this be a DIY project,?

Should I get it fixed ASAP?

There's also a crack in the concrete in the pool as well in the corner in the water. It sticks out about 1".

Hydro-jacking or slab-jacking looks like the opposite of what you need -- it looks like you're wanting some slab-UN-jacking.

Unfortunately, that gear is available only from the stores where they sell Boy Scout snipe in ready-to-use cages, board stretchers, and unsaws. I've never been able to get an address or URL unfortunately, for their location.

Cybernation,

Your best bet is to remove and replace. If you hire this out, make sure they put an inch or three of 3/8" crushed "road base" rock and hand compact it before pouring the new deck.

To explain --

Road base rock has a specific amount of various grades of fine rock chips and sand in the mix as opposed to "clean" which is 85% same size material.

You want the "fines" in the mix for your application, to help with the stability. The fine components will lock it all together, and aid in the compaction process.

Have you had an unusual amount of rain this year? From your pics, it appears that the underlying dirt/clay has expanded/swelled from high amounts of water in a short period of time.
