Bamboo breaking through pond liner

Hi, I'm new to this forum and wondered if anyone could give me some
advice.

I know some bamboo species can be invasive but having planted it before
and not having had much success in the past, I thought it would be okay
planting one on the edge of my patio and fairly near to the pond we
built a couple of years ago.

What a mistake it was to be as the bamboo has flourished and though
looks beautiful, it has been breaking through the pond liner and thus
reducing the level of water on a regular basis.
I have effectively 'buried my head in the sand' until now but the
problem must be remedied as topping up the pond is becoming an almost
daily task and I'm worried about the risk that reduced levels will have
on the fish in the pond.

The liner is a heavy duty rubber one. Someone said to me that I could
replace it with a special type of cement which would prevent subsequent
bamboo shoots from breaking through.
Is this the case and if so, what is this type of cement called? Are
there any other suggestions you may have? Any other material that will
be impervious to bamboo shoots? Or will I simply have to dig up the
bamboo. If so, you'll know, this will be very difficult to carry out
successfully.
Thank you in advance.
