Thanks for the response Jimmy! I am renting a CAT 315? The connection I have at the rental store is going to give it to me for the weekend for a days rate. I wanted to get the 320 but the costs were too high. Did you DIY your pool base? If so, where did you source your material from?My advice is to take time off and spend 2 weekends amd the week between solely on the build. Depending on your ground a novice can get into a bad spot quick with rains. Dont know how deep your going nut a mini excavator isn't gonna be fast on a 20x40. I wouldnt do it unless I had no choice on access and would charge extra for the time wasted. An 80 class machine is the smallest you want, that's a 18k pound trackhoe. I dig with a 160 takes half a day tops, and relocating piles is easy. If ur buddy excavated he should know somebody for a machine. Be aware many pro excavators do horrible jobs on pool digs. They usually overdig you dont want that. A cleanup bucket is best for a rookie after you get close to the wall height grade. It seems exciting to start and do it all, you wont feel that way after a few days. Make sure ur help is gonna actually come amd reliable
Does anyone have any guidance on where they sourced their PoolKrete or Vermiculite from? Trying to save the 300-500 shipping charges from buying it online.
I am considering subbing this part out but so far, I have not found any concrete people that work with poolkrete or Vermiculite? Am I asking the wrong questions?
Looking to break ground on April 24th depending on the weather. Can't Wait!
Thank you! If you don't mind sharing, what did it cost you to sub out the pool krete?I got my pool krete from a local hardware store about 30 miles away. You should be able to find some locally if you do some calling around.
I subbed out the pool krete and I am glad I did, they made it look easy and did the whole pool in less than a day. You will probably not find a concrete guy that also does pool krete, they really are a different skill set. I had to call a few pool install places to get the names and numbers of pool krete guys. It's like pulling teeth to get a name and number, they want to put your whole pool in for you. Once they find out you are doing your own pool, they don't want to share the contractors that they use with you. Maybe you will have better luck than I did, I ended up getting one of the best guys around to do mine and could not be happier...but it was shear luck that I was able to get his #.
Jimmy is 100 % right in the recommendations he made. I used a full sized track hoe and it made quick work of the dig and moving dirt around. The larger track hoe can not only dig faster/deeper, but has a longer reach to pile the dirt more out of the way. I took a week of vacation time that started on ground breaking day and with the 2 weekends in there got a ton of work done.
Yea that does sound terrible lol. I guess my math was off on the bags per yard. We are paying 150/yard here though. My pool is 20 x 40 with full-width stairs. I assumed 7 yards for the bond and 1 yard for the stairs? I am struggling with the calculation on the stairs. Do people fill the whole stair part with concrete or backfill it with stone than concrete? I just want to make sure I do not have bouncy stairs.You don't state the dimensions of your pool...but assuming it's an 18x36 rectangle pool...and the bond beam 2' wide by 8" deep would take right at 5 yards of concrete. It takes 45 bags of concrete to make a yard, so you would be mixing 225 bags. YIKES!!!
That's also over $1k for 225 bags (Lowes), here you can get concrete delivered for about $115 per yard.
My pool has full width steps with a tanning ledge which was 8'x18' in the bottom. Is yours just 3 steps? If so the steps are normally 1' 2" in width...so your bottom of the steps would be roughly 20' x 3' 6".Yea that does sound terrible lol. I guess my math was off on the bags per yard.

Also, for backfill, does 45 tons sound right for 4' walls on a 20 x 40 pool? I plan to use a washed # 8 (3/8-1").
Wow thank you for the detailed response. Super helpful! And of course, I wouldn't hold you to itMy pool has full width steps with a tanning ledge which was 8'x18' in the bottom. Is yours just 3 steps? If so the steps are normally 1' 2" in width...so your bottom of the steps would be roughly 20' x 3' 6".
Steps (provided that you fill the bottom inside the steps 8" deep, I put closer to 6" inside my steps)
20 x (3+(6/12)) x (8/12) = 46.7 cu. ft.
46.7/27 = 1.73 cu. yd.
Bond Beam (8" deep all the way around)
(20 + 20 + 40 + 40) x 2 x (8/12) = 160 cu. ft.
160/27 = 5.93 cu. yd.
So it look like you will need roughly 7.5 - 8 yards of concrete. That is if your space from the back of the walls to the dirt is a full 2'...if it's less/more in some places you would need to take that into account. I would suggest pouring the beam 1st and make sure you get a full 8" depth all the way around. Then pour inside the steps and if you are a little short, it will not matter as long as you get 6" or so in there.
The gravel backfill is figured the same way. The steps are a little tricky, but I would break them down into 3 columns to calculate. I also poured concrete for the top surface of the tanning ledge and steps rather than pool krete. I was told since the water was shallow the force of jumping on it could cause the pool krete to dimple where concrete will not. I covered the entire steps/concrete in a layer of foam before installing the liner. So I had concrete in the bottom, then gravel up to about 2" from the top of each step, then put 2" of concrete over that the day I poured the 1st part of my deck.
Wall Back Fill (should have a height of 34 inches since the bottom 8" of the 42" tall wall is concrete)
(20 + 20 + 40 + 40) x 2 x (34/12) = 680 cu. ft.
680/27 = 25.2 cu. yd.
Steps Back Fill (assuming they are 1' 2" wide and roughly 10" tall, remember to take out the 8" of concrete)
Bottom Step 20 x 1 x (1/12) = 1.6 cu. ft.
Middle Step 20 x 1 x 1 = 20 cu. ft.
Top Step 20 x 1 x (22/12) = 36.6 cu. ft.
59/27 = 2.2 cu. yd.
So roughly 27.5 cu. yd. of back fill gravel
No warranty expressed or implied, but I bet those numbers are really close.
I asked for a 2500 mix. Should I be using something different than that? Can you elaborate on the stair process? Are you saying fill the first two steps with concrete? If so, do I board it up once its filled to keep it in place during the curing process?We use about 40 tons for a 20x40. Your gonna need about 9 yards for the footers. Domt even think about hand mixing would cost way more plus killing yourself. Call around 150yrd is alot you need basic mix for this. I fill stairs to 2md to last step with additional form
Hello there,A 315 is fine, I thought you said mini excavator? Get largest bucket if they have a 24" or even 30" a clean up bucket is great for fine tuning (no teeth on bucket just flat bar) look online for pool supply house near you, they might sell a DIYer pool base or have no issue with non pool pro sales. You can get premix and do it old school without a mixer. When you pour your collar make a form amd pour the deep end hopper same time in concrete. Mext day use that as a mix point amd you can open a few bags amd garden hose it flipping with shovel amd turning it. Once oatmeal like, slap it on amd trowel it. Set string lines and guides. A 20x40 is alot of work, anyone good with a trowel can apply it. Need a Fresno to make it nice. A pro will make it very flat, you only see imperfections under the pool lights anyway
