Hello new pond guy here,my question is ive just finished doing a pond,(of course i find these sites after ive done the job)and it looks great put unfortunatly the friend i got to do the edge paving but the base concrete on top of the liner now the water is levelling it self out below his concrete & leaving an unsitely mess ,i now no the liner should have gone in AFTER the concrete went down but its to late now of course,i wonder is there any thing i could do to hide it as it varys in depth around the pond,i was hoping to fill it up right under the paving but as its soaking away plus when it frezes,any advice would be great,cheers.

Hello Dude69, welcome to the forums.

Could you please clarify for me what the problem and question is.

well i just want to disguise the concrete around the edge some how.

oh. I see.


Concrete / cement around the edge of a pond should be well above the water level because it contains lime. Lime is toxic to fish. You can how ever "seal it" with something like G4 "pond paint" (Other brands of "pond paint" are available) G4 is also available in black. (Honest, its available in black or clear)

I presume your liner is black?

Thanks for that,i will have to try some of that,with hind sight the concrete should have been done first & then the liner go down,but hey ho we live & learn.

So, if im reading this right your hole was dug, liner put in then concrete? was the concrete just for the edging stones or has your mate covered the whole of the liner?

nope just the edge of the liner,a ballest collar went down first,on top of the liner,then the motar for the paving,ive now got a nasty lump of concrete showing all round the edge.
