Runners will not damage concrete, clumpers will generate tremendous
pressure against concrete it comes in contact with. Runners may pop
up through your plastic pond liner, this has happened to other people.
If you were to have a concrete pond, you could plant runners around
it and be ok, if you put clumpers in you can have the plastic liner,
however, you will have to keep the clumping bamboo cut back from the
edge to prevent damage.
