    Ok, I appreciate that C16 would be strong enough but C24 would absorb less moisture .
    You say you wanted to know about durability and that was the reason for the post.
    With 50 years experience and many qualifications in construction, I estimate 2 to 3 years till partial failure, less than 5 years, total failure.
    But like I said earlier your bucks your choice

    If you're right, then that's most certainly not a good economic choice.

    if you're going to back fill with concrete anyway,
    how about shuttering and pouring concrete behind it?
    you can then bin the shuttering and have a solid concrete pond to fibreglass

    To close this tread.

    Thank you every one that has posted.

    I have listened to all that has been said .
    To end I have sent and have had replies from TRADA, the last word in uk timber, and also Harlow Bros, where I have bought the wood from.

    They say that my design is fine “belt and braces,”but I must keep the wood dry before the fibreglass. The wood I used, on its own will last 10 yrs guaranteed.

    Building materials are going thru the roof due to HS2 , brexit, COVID and the Russians and Americans (last one via Harlows)!

    Comparatively at least the fish will not be too expensive, if I ever get water into this thing!


    Thank you everyone for your input and when it leaks you can always say I told you so.

    "Comparatively at least the fish will not be too expensive, if I ever get water into this thing!"

    First I would like to apologize to forum members who read this!!

    You are a complete dickhead, if you have fish they are living creatures the same as a dog or cat and you are responsible for their well being and care to the best of your ability.
    Clearly from that statement alone all that matters to you is ££ so I hope you never build that pond because with your " it's to much money" attitude the poor fish will die due to lack of care before your pond fails.

    Personally. Having listened to an “expert” builder and have my first pond literally fall apart, I’d be loathe to build another pond any other way than the tried and tested methods.
    I’ve seen a few bent sleeper ponds so there’s no way I’d be using 2” planks irrespective of where they’re supported.

    Unfortunately there’s a lot of people who come on here looking for their preconceived ideas to be confirmed and no amount of advice will change their mind.
    When they don’t get to hear what they want to hear, they generally bugger off with their tails between their legs. Never to be seen again
    My advice is, listen to those who have done it or learn the expensive way, like I did.

    sorry if I upset some of you but?

    In order to build my first koi carp pond right and thus produce a good home for my fish I decided to find out first, before I started building .

    I have spoken to professional koi experts visiting serval dealers, read books, including Peter Waddington,s “ the path to understanding”., visited. several ponds, from basic to expert level and watched numerous vids on y tube.

    During this research it was suggested that I ask , on this forum site about fibre glassing timber ponds. This I have tried to do.

    As an engineer with over 42 years in designing and supervising builders in construction I did not expect to be called a dickhead. No builder has ever called me that, in fact most builders small to very large have thanked me for my help In sorting out their problems and their clients for putting right builders mistakes!

    The design I am going to use is not mine, it is by an American company,

    https://russellwatergardens.com/page...ild-a-koi-pond

    with regards to my own design I have, for example a 3.6 m high close boarded timber factory screen fence, with timber posts and this is 25 yrs old and is still in good condition.

    As regards to the care of fish I have had tropical fish most of my life and also have a smaller goldfish pond, all of which I have looked after properly


    Because of the high timber prices I have bought the wood for £850. Block work masonry is much more expensive than this, with bagged opc hard to get hold of. My overall project budget is £6000?

    Ok first, this company no longer trade in Washington state, ( I wonder why) they now trade in Arizona ( very low rainfall per annum ,9" compared to 54" in the UK)
    Second, they install liners in the ponds, not fibreglass!
    Third, site engineers normally over see building works
    And to end, fences are normally treated at regular intervals and are above ground so are able to air dry, not a very good comparison to timber (especially softwood) underground

    Hum
    Firstly. I have no idea why they moved but I do not think it was because of the rainfall. Are you saying this company are wrong to suggest timber. What about insect attack!

    Secondly. That is why I wrote the tread in the first place. I wanted to know about using fibreglass.

    Thirdly. You are just wrong. Site engineers work for the builder I worked for the client.

    Most site engineers are involved in civils, drainage work etc. in the case of the housing industry they work for the subcontractor,

    I was employed by the client house builder. Barrett’s, persimmon etc . Because the builder and his site engineer were surpose to be building to my B Reg approved designs, which the client paid for!

    To End the foundation in my design, were sw timber posts embedded in concrete. How do you paint them?

    You can't paint them once they are in concrete that's the whole point, once in the ground they will not get frequent coats to protect them so your comparison to a fence is flawed... a fence with timber posts will be lucky to stay up 5 years let alone 15... the advise being given by others on here is good advise, please listen to it.

    Put fencing up for many years now at work below ground is gone with in 5 years as dbs has said my home ones have lasted 10 and but we're that rotten I put the hose against when I dug them out and they crumbled with the water for the hose... You can buy sleeves now for the posts but I wouldn't waste my money.. Unless you can completely water tight all sides of the timber with the fiberglass it is going to rot end of
