Kathy,

It depends. If the concrete pad is 6" thick then the bamboo should not
bother it.

If the distance from the bamboo to the pond liner is less than the rated
height then your liner is safe. If it is less than the height and the
variety is a phyllostachys then the bamboo will probably puncture your pond
liner. Rhyzomes are indeterminate in length and will continue to grow for 3
years or more and can extend a length from the grove the height of the
tallest culm.
