Seeing as there is such a wealth of knowledge and experience at IIS, I thought I would try my luck at this question.
I have just completed building a 6 square metre fishpond, constructed below ground of a bird mesh liner first, with rock jigsaw-puzzled together with concrete. It is very solid, but I understand it will crack over time as the ground swells and contracts with the seasons. (much more in 2012
)
My plan at this stage is bomb-proof, but expensive. I plan to paint it first with bondcrete, then line it using a medium fibreglass mat and resin.
It's in an undercover area so I am leaving the UV stuff out (extra cost) and want the fibreglass semi clear anyway so you can see the rockwork underneath.
The fibreglassing process will cost me about $350 for the materials.
Just on the off-chance, does anyone have any other suggestions that would be effective but cheaper, to make it permanently leak-proof?
Baz.
