Above Ground Radiant 27' Metric Build

[KPROMERO]

Hello all. Today I will be starting my replacement build on my new pool. Old pool was rusting on the top panels and slightly on the walls which was installed also by myself 8 years ago and was semi-inground. I will be installing new pool also semi-inground since this part is already leveled, checked with a transit, and everything pretty much completed and ready to go. I will post pictures in the process and post as i go through it day by day, which i am hoping to have complete by this Sunday, fingers crossed.

Here is what i decided to go with and do with this build:
27' Round Radiant Metric Pool with 52" walls. This pool has a lifetime warranty, not pro-rated, aluminum and foam walls that are 2" thick, and can be installed above, semi or completely inground, can have a SWG hooked up and none of this will void warranty.
Here is website about them:http://radiantpools.com/
After researching I decided to go with this as my choice to fit my needs and pretty much had not seen anything negative about the pool.

While the walls will be going up in place, i will be raising the pool walls up 2" from where the old pool was, then placing some metal landscape edging around the inside to be able to pour concrete on the outside to use as a collar that the pool will rest on to help keep level and add some strength i figured. Under the walls it will be 2" thick and on the outside of walls it will be 6" x 6" thick. Roughly 1 yard on concrete will be used for this.

I will be using 1/2" foam padding 4'x8' sheets for the flooring and also Gorilla padding will be placed on top of that with foam pool coves to go around the edge.

Installing a Burndy water bonder and also bonding rest of pool with 8 AWG bare copper wire. Not sure yet about adding a Zinc Anode to it since from what i have read aluminum is softer than zinc so will not help much to reduce possible future corrosion if it may happen. Currently have a Circupool RJ-45 SWG installed which is 2 years old and sand filter system.

After pool is filled with water, i will be using gravel about 3/4" to 1 1/2" for back filling since i have a heavy clay soil here.

Pretty much it for now of my plan. Let me know if i should not do something in the above that you would not recommend and why. Thanks and be on the lookout for pictures of build in progress.
