    I'm in CT so temps never really get cold enough to freeze during winter.
    They're talking about copper piping (not sure if that makes a difference?)
    Basically if they opt to take off tiles to fix the problems (which will result in them having to retile the whole bathroom as that tile isn't made anymore), then they will only fix the current problem, and leaves the potential for more problems to occur in future (we've already had one leak fixed in the same system, but it was easier to reach).
    Whereas if they reroute it all to outside then they will essentially redo all the piping and stuff from scratch, so it will all be done properly. It will include moving our bathroom cupboard (built-in cupboard - 50 year old house) for the pipes for the basin. But it will all be done properly and the likelihood of future issues is significantly reduced.
    [Basically it sounds like whoever redid the bathroom before we moved in (probably 4-5 years ago) never did it properly]
    But it all boils down to whatever the insurance prefers, so for now we just continue to wait and see. Have never had to wait this long on insurance before, it's rather annoying.

    Ohh well then maybe outside will be better in the long term. Don't really want to have a repeat of this :(. Copper pipes just last longer then galvanised piping.

    Hope you get some good news from your insurance soon.

    The foundation/base of the pond got finished off today. Thursday the brick walls will be built.

    We put a solid sheet of Dpc Plastic on top of the foundation that had been built this far, folding it right up against the house so that of ever the pond does leak, it should provide protection to the house against damp.

    And then added a layer of screed, which had waterproof cement additive added into it.

    It's happening! Brick work has finally started.

    20220728_103306.jpg

    It looks like the final inner dimensions of the pond will be a bit smaller than I initially thought (I think we had the outer dimension in mind and didn't factor in just how much smaller double layer brick would make the inside), but it will still be a very good size.
    Guestimating how much space plastering will take, the inner dimensions will be around 85cm wide by 2.65cm long.
    I haven't worked out the exact height/depth yet, but I'm guessing around 80cm.
    I want the final pond to be similar height to the existing one, but this one starts slightly below ground level so the depth will differ from the current pond a bit.

    We've done a 15cm gap between the bottom exposed bricks of the house (so the not plastered wall) and the outside of the pond. Once the pond walls get up to plastered wall height I guess the space between the two will be probably closer to 13.5cm roughly. We'll fill that with expanding foam and then plaster over the whole lot and paint it. There's also the dpc plastic protecting the unplastered brick section (I guess that's part of the house foundation?) from any potential leakage from the pond. So hopefully those measures protect us from potential damp issues.

    I'm still not 100% sure about how I'll waterproof the final internal part. I want to add waterproof cement additive to the plaster mix, which will be applied both inside and outside the pond. And then we'll probably paint the inside with Durapond as well (and possibly bitumin as well - I think @Bart said he did that), but I'm not entirely sure I trust that as a final finish, so I'm still leaning towards lining the pond with an actual liner. Paint would be a neater finish though, and I'm struggling to find anyone that sells DPME liners, but I'm so nervous about leaks that I'd feel more comfortable with an actual liner. So ya, that part still needs to be figured out.

    Here you can see the gap between the house wall and the pond wall. (15cm)

    Taking shape.

    Here's a better pic of the gap between the pond and the house.

    nice to see work happening
    have you thought of swimming pool marblelite to seal it up?

    No I had not thought of it - never heard of it!
    We did briefly consider fibreglass, but when I read up on it it seems very complicated and expensive to apply.
    Not sure about the costs of adding marblelite. I just did a quick google and at first glance it appears you need an actual pool company / specialist to come and install it. And all the websites require you to fill in forms for a quote, so no easy/quick way to get an idea of costs. I might fill in one form though just to get an idea.

    Looking good so far. :thumbup:

    You can also use liquid rubber to seal the inside of it.

    I've gotten a quote from a pond liner company and a pvc liner (they don't recommend hdpe for a pond my size) would cost only slightly over R1000 so that'd not too bad at all.

    However hubby and I have discussed the options and we're going to give durapond a try.
    I will be adding waterproof cement additive to the plaster mix which will cover the entire pond, inside and out, and then 3-4 layers of durapond on the inside and we'll see how that holds up.
    If it's a total flop there's still the option to add a liner afterwards.

    Up to seven layers today, just three more to go and then we can plaster it.
    (the bottom three layers will be below ground level when it's all finished and the sand is put back in its place around the pond)

    After all that stress you must be so happy to finally get the building going!

    I really am!

    The brickwork will be finishing up today. I've settled on 9 layers rather than 10. It just feels right to me.
    We've just slotted in an overflow pipe (hubby really wants one, I don't really feel it's necessary as I never fill my pond that full).
    Tomorrow the pond will get plastered, and then we'll wait a few weeks (or until at least end August) before applying the waterproofing paint etc. So won't get filled until Sept, but at least it will be a completed structure!
