cement sealer or shotcrete for pool ?

A client has asked me to construct a pool using a cinder block structure sealed with a cement based sealer like drylok or hydro ban, as much as I understand this method can work, I believe shotcrete would be a more reliable option with lower chances of leaks over time. I want to take on the project but also want to ensure it's built to last using the best approach, most of what I've found online involves block pools with liners, which seem prone to wear. Would love to hear from anyone with experience, is block with a cement sealer a good long term solution, or should I push for shotcrete?
 
We didn't have all these fancy options then but I've learned to trust what stands the test of time. Shotcrete is a solid choice for durability and leak prevention particularly compared to block pools with liners.

I know a few people whose pools are made with shotcrete and they haven't said anything about any problems, so I'm guessing it does a good job

In order to prevent leaks, cinder block pools sealed with Drylok or Hydro Ban require careful construction and maintenance. Shotcrete typically requires less maintenance and creates a stronger, more waterproof shell. Shotcrete is the more durable and safe option if money permits

For a pool, shotcrete is vastly more reliable for long-term, leak-free performance than cinder block sealed with cement-based products. Cinder block means more seams and reliance on a surface sealer, increasing leak risk over time. Shotcrete creates a strong, monolithic shell, which is why it's the industry standard for durability. Push for shotcrete for a pool built to truly last.
 
I honestly doubt there is a single person with a shortcrete pool that has had any kinds of problems. I do have to say it needs to be done properly for this. Is there a specific reason why the client is requesting this?
 
That's a great question. When it comes to long-term durability and preventing leaks, shotcrete definitely comes out on top. While using block with sealer can be effective, it requires meticulous preparation and ongoing maintenance to steer clear of potential problems later on. I'd recommend asking the client about their preference for the block method,are they focused on budget, the look of it, or perhaps they've just seen it done that way before? If they're open to suggestions, I'd really advocate for shotcrete to give everyone some peace of mind.
 
Honestly, if you want that pool to last and not become a future headache, shotcrete is the way to go. Block with sealer can work, sure, but it's just not as forgiving long-term.

Hey, I'm curious what you ended up doing on this project? Your initial thoughts were spot on. While a well-executed block pool can work, it's hard to beat shotcrete for long-term reliability. We always steer clients towards it for that truly monolithic, leak-resistant structure. The upfront cost is higher, but it pays off significantly in terms of durability and minimal maintenance compared to liners or the potential issues with block and sealer over time. Hope it worked out well!
