Hello pool/spa pros

I'm picking up with a DIY project where someone left off. I need all the advice I can get on waterproofing the inside of a poured concrete structure which will be used as a baptismal at our church.

The structure is 8' X 8' X 3' deep and is under a platform so only the inside can be seen. The structure is above ground so no pressure from water from the outside.

Help!!!
Thanks!!!

Has an engineer looked at it to make sure it is safe for water? If so there is a new product called aquaBright that might work for you. Do a search and see what you think.

If you need to continue DIY, do you have any masonry skills? If so, I would simply plaster it. You have a great work area and a small enough job so you could finish pretty quickly. Plenty of you tube videos.

LOL!! It turns a screen door into a boat. That could actually work, especially if it is left empty for periods of time. Pretty easy touch up too if needed.
