Good prices, shipping expensive, try to do only one order.
PVC glue, I liked the heavy duty, not regular or medium duty.
Goop it on!
Planning for the last joint in a subassembly or run is important.
Leak test at 15 psi, I did not pressure test, dangerous.
Air molecules are smaller than water molecules.
It will find a leak or dry fitting pretty quick, less than an hour.
8 hours and no pressure drop, your golden.
Temperature changes throughout the day can give false readings.
And, .... can blow out temporary plugs.
Forming benches, platforms, stairs.
I really have not come up with a good way to do this.
Base, sand bags, cinder blocks, ???
I did with wood, I would not do it that way again, too much labor and cost. Gunite guys did not like either, they are not used to seeing it. It just holds the Gunite in place till it cures, the Gunite is the strength structure holding the water. I’ve used in the past and even removed the forms later. In this case, they will rot away in time.
Each pool is unique, have it design for strength needed, I used my thumb. Have had lots of experience in foundations.
I used #4 grade 40 , 10” centers
For walls, 12” Gunite, double rebar mat was my design.
Grade 60 is too hard to bend.
Bending over splicing I recommended.
A bit more planning, but I believe better in the long run.
Good tying is very important, your going to have guys walking all over it. It should be solid! Tight!
I prefer dry mix, I believe better.
Messy! Lots of waste.
Waste, have them make small piles, easier to dispose of later.
Tarps, plastic, boards, be ready.
Tarps, used billboard road signs, heavy duty!
$20 for a 12’ x 50’
You want to keep the natural stone pretty.
Protect above the top of Gunite boards with plastic stuffed behind the top of Gunite boards.
Plug the outside of big gaps, you want them to shoot into the gaps to firm up the dry stacked blocks.
This is hard labor shooting Gunite.
Be nice, but double check there work as they go along.
They may not be able to read blue prints, they will just shoot about 3” on top of the rebar ...
Top of Gunite should slope out 1/4” to 1/2” for setting coping later.
When they scoop out around the stub outs, returns, have them wash the pvc pipes clean with a sponge. Real pain after it’s dry.
Coping and tile by one contractor!
I did not like the poured coping option.
Everyone does things differently.
Very visually important.
Layout all the coping for back slope, high spots, ...
Measure and come up with a plan so you don’t have one ugly short piece of random coping.
Set the 4 corners first, you now have 4 inside fits.
Plaster crew was awesome, need very little direction, lucky.
Wow. I completely missed this build/thread. My thought: Is there enough of a barrier so you don't step into the pool from the patio? Like little kids running around, slip and boom into the pool -- I could picture it so clearly.
I love that people driving by won't see the pool. It's hidden from view with that block border. It's genius! It turned out so well. I assume you were your own contractor and hired workers while you oversaw it all? Simply amazing.
I bet you're going to kick back and enjoy the rest of the holidays. Rest.
What 8 returns, on a very small pool, does to back pressure?
This is with all plaster dust removed. 200 sq ft cartridge filter.
SWAG we’re flowing 75-100 gpm in a 4,400 gallon pool.
Will put in smaller eyeballs to increase velocity and better wash the bottom.
