Thanks for your reply. I like the concrete look so I am not worried about the colour. So I am guessing they wouldn't be strong enough to put sn outdoor spa on?
Hi @Cassie. I think that @Brad suggestion to put a (reinforced) concrete pad down and pave around it is a good idea. It would be a fairly easy job to do and you can work to the thickness you need. You will never have to wonder or worry about a significant load on pavers or besser brick caps that aren’t designed for that load. Good luck. @Allan72
Thanks Brad, they sell a platform at the Spa place that I could prepare the ground in the same way as for the pavers then the spa platform in the spot I want it and pave around it. Thank you. Vey helpful advice.
