Raise the deep ?

[Krobins22]

Its it super expensive to raise the deep end of my 21k gl pool by 3'. Vinyl liner with 6ft of 5ft depth then steep decline to 10ft.

Welcome to TFP.

No, just expensive.

What are the dimensions of your pool and how easy would it be to back up a concrete truck.

Without dimensions, would have to guess.
My math here is 21,000 gal/7.48 cf/gal = 2,807 cf.
If ave depth was 7.5ft, then 374 sf. Going standard size about 24 x 16
Assume you have 4' slope from the walls to the deep end, you would have a hopper about 8'x10' at the bottom sloping up to 16'x18' at the 5' level. So, at the 7' level you would have about 12.8x14.8. Filling an 8x10 to a 12.8x14.8 is about 386 cf or 14.2 yards.

Not sure what flowable fill runs, but assume about $120/yd, so somewhere around $1,800 plus another $100 to raise your main drain. This assumes you can do it yourself and if you can back a truck within range for the shoot to reach, you are just dumping it in. If it has to be wheel barreled in, that's a lot of material to move by hand.
