Concrete Ring Cistern - Experiences

Because it seals tightly and doesn't need constant repair...
He did write that after all.
There is also a warranty.

Because it is tight and does not need constant repairs... He already wrote that. There is also a warranty.

Yes, it may also be that it is only like that for him. I heard from a colleague who also has such concrete rings and has never had any problems with them for 20 years.

Maybe he hasn’t noticed yet how much water is leaking... The effort for sealing, record-keeping for pipes, etc. is quite high. Plus the time involved. Still, it can work. I would rather rely on something ready-made.

I see it the same way ... otherwise we'll soon have the thread "Help, my cistern is leaking water" ... oh no, that one already exists ...

Hello Exto

For the concrete channel rings, you have to pour a base, seal the joints, etc. Also, they are rather small in diameter. Or you take the 200 rings. But they also cost around 500 euros per meter. A 10m² concrete cistern costs about 2,500 euros. And you always have peace of mind. If there is someone who can dig the hole cheaply for you, that is already half the battle.
