Very cool return. Looking good!

Hello all, here's the latest upload : https://www.youtube.com/watch?v=1HaG0yCKJZk&t=7s
It's all coming together, the pond liner is in, pond filled and testing for leaks along the pipework.
The electrics are done
Pipework between the filters complete.
Hello all, an absolute disaster this morning, hard to put into words .
Can go under "lessons learned", maybe it'll help someone avoid the same with their builds : https://www.youtube.com/watch?v=scfndLvPGo4
Oh my God... Heartbreaking. No rebar reinforcement in the corners?
Wow, I'm so sorry. But thanks for sharing because like you said, you can't underscore the importance for rebar support enough
and hopefully it'll be an example for others that are sure the block and mortar will be enough to hold all that water.
I'll be watching for the rebuild... it'll be good to watch how he corrects it.
Man that sucks, waiting for the come back.
So sorry for your loss, but thanks for sharing. I hope you will be able to add some tension reinforcement between the double block walls, and/or add a mid-point bolster/brace in the long wall.
A good reminder for all of us of the pressure of water. This is an above-ground wall, but similar results can be experienced with below-ground unreinforced block walls in certain soil conditions, just without the explosion.
Concrete has little tension strength to begin with, and as it cures it shrinks and cracks open removing all tension resistence. It is only the embedded rebar (and/or fibers) that provides the tension resistance to to keep the cracks tight and provide the strength to resist the water pressure.
Hi guys, thanks for the comments . Still can't quite believe it .
Hello all, sorry for not giving any updates sooner, been a tough week but things are now starting to move forward .
Thanks for all the suggestions and comments .
Have discussed the various options with the builder, he's also taken further advice from other builders and is going for the following approach ( I did offer to pay for a structural engineer but he's 100% confident with this new approach ).
The foundations will be increased in width, this will allow for a double width block wall ( laid alternately on each course ) plus further foundations out from the wall with further bracing on these back to the wall . I will also back up with soil to add a further level of support ( this will be hidden under the decking ) . The walls will also to tied into the existing patio wall as before .
The blockwork does go up fairly quickly so will hopefully be in a position to fit the new pond liner in the next week or so .
Here's a link to this weeks progress : https://www.youtube.com/watch?v=6Vxv8L-Bs-k&t=133s
And some photo's that will hopefully make sense of my description :
It worries me a little that you keep referring to your builder using extra "bracing." From what I have read on this forum, everyone who builds a wall pond successfully uses a lot of steel reinforcing rod (rebar) embedded in concrete within the wall. If he is not doing it like the successful ponds on this forum, I'd be worried. Don't argue with success.
I wouldn't trust unreinforced masonry at all for this purpose.
Hello all, finally had signoff from the structural engineer today, has delayed things a little waiting for this .
Here's the latest video : https://www.youtube.com/watch?v=_KjGVMS2BR0
Will now be able to completely fill the pond , switch the pump on and start testing the filters . Hopefully get some koi in the pond soon before the weather turns too cold .
Sorry guys, haven't been posting for a while , but good news ….
This is the one where the fish go in : https://www.youtube.com/watch?v=-LvErSErcbc
It is a bit fish heavy, I think I got a little carried away . Worth watching till the end for the underwater view of the pond.
Still a few jobs to go and some fine tuning over the next few weeks .
Nice...I like the window. I know you must be thrilled that it is holding water!
Hello all, another update : https://www.youtube.com/watch?v=J0uklmGgx6Y&t=7s
The lights have gone in, need a bit of adjustment but pretty happy with them .
Did my first water test, thankfully looking OK .
And, a walkthrough of my filter setup . Will probably add it to next year but should be OK for now . Thinking of adding a bakki shower over the moving bed filter .
Nice comeback.
That moving bed k1 one filter though. I bought 3 cubic feet and it’s still in the shipping containers
