    Hi all

    We are making a marine pond, or actually we are planning it. The pond will be 3 X 1.5m more or less and will be build out of bricks and cement.

    Now my question is that with what do i seal the pond to make it reefsafe and leak proof?

    Any advice on this will be appreciated.

    Forgot to add the depth, it would be 0.5m more or less

    I built a freshwater pond at my house Dikdaan and researched a few methods. The top 2 i think from a leak-proof and toxicity perspective are fibreglass and bitumen. I chose fibreglass and am happy with it - although bitumen is ALOT easier to work with.

    Also bear in mind that if you use bitumen you are prob limited by colour to black. So, if you want a turquoise blue marine pond I would suggest fibreglass

    You can get all the raw materials for the fibreglass at harveys composites! Very professional guys. I dealt with a guy named Vees Moonsamy and he was very helpful and knew what he was doing!

    p.s. I also have LOADS of leftover fibreglass matting that you can take at 50% of the price if you decide to go the fibreglass route

    Thx Jaybee, will let you know what we decide to use. The black wont be a problem. What is bitumen? I have never heard of it... Is the fibreglass safe with the saltwater?

    Bitumen is like a rubbery substance that you paint on over the plaster! Most pet shops that sell Koi use bitumen on their holding tanks - you will notice it as a spongy black lining on these tanks so have a look next time you are at a fish shop.

    As far as fibreglass I found this quote through Google:

    The resin is fish safe after it has fully cured, however it is just ugly. Dye/coloring can be purchased for it if you don't really want to coat it with something else. If the resin is not mixed well, it will remain sticky after it has cured. It will then need to be coated with something else.

    There are two predominant types of resin, isophetholic and orthophetholic. One is marine duty and the other is not; I don't remember which is which so you will have to do some research. If the resin at the auto parts store does not say it is suitable for marine use, then do not use it. Look in your phone book for a fiberglass supplier. They will have the knowlege you are looking for. The will also have the tools you will need to do the job properly...including a vapor mask so you don't wake up in the morning with a headache.

    So ask the guys at harveys - im sure they will know!

    avoid bitumen at all costs! it can not handle the water presure of a deepish (more than 2 foot) pond. Have a professional fiberglassing company come in and do it with a black dy in the resin.

    the top resin layer will be pool coat:) or you can paint over the normal resin with polyurethane epoxy supplied by prominent paints and mixed in colors

    i think dikdaan is talking about the bitumen paint you buy at builders - i really would avoid that. Fiberglass is expensive - cost +- R68 000 to redo my koipond after i moved in
