Suggestions regarding building a block pools

[Transy416]

Greetings. I've been researching pools for the past few weeks and am somewhat interested in a plastered (or other surface like Sani-tred or Armor Guard) concrete block pool. I realize vinyl would likely be much simpler. Any feedback is welcome.

Hi Transy416 and welcome to the Pool Forum!

You'll probably have a better chance of getting some replies if you post specific questions about the things you are researching.

Hope you enjoy participating on the forum and find it helpful!

Thanks Watermom. To begin with, I understand it appears recommended that the floor and footer be poured at once, with rebar passing from the floor going through the footer and vertically up the walls. i understand that when the blocks are placed over the vertical runs of rebar, the walls and floor will be unified. However, since the blocks are dry set, what bonds the block walls to the floor of the pool to prevent leaking at the connection? Is simply filling the cavities with cement sufficient? Is a waterstop needed, and if so, how is it placed with the concrete block? Or is the surface bond coat along the face of the block sufficient to create a unified connection at the floor and wall joint?

Once the walls and floor are in pace, I understand the plaster/diamonbrite/sani-tred/armorguard seal the floor and walls and ultimately waterproof everything? Any recommendations insofar as which surface coat is best?

Feedback greatly appreciated.

Concrete block pools were fairly common years ago, but judging from the pools I've seen, have not been built much since the mid-70's. I've serviced block pools, but have never seen one built. If you can find an old pool contractor who was active in the 1960's -- 50 years ago -- he might be a great source of info.
