Waterproofing cement

[willcarter]

Hi All

I want to seal a layer of cement around the top of a pond to make it waterproof.

Could someone recommend a product widely available in the UK that would do this for me, and that wouldn't be poisonous to plants and pond wildlife?

Thank you,

Will

No brand names spring to mind as it's long time since i used any such thing, but any pond suppliers will have something I imagine.
