If you want ot put a membrane coating on it that is able to be applied
by anyone who can use a brush or roller, check out Sani-Tred. They
make a rubber coating designed specifically for concrete etc and fish
ponds. I know a few who have constructed gunite or concrete block
ponds and merely applied a coat or two of this Sani-Tred to the
surface and its water tight..........They also make a special
thickened rubber paste for filling in cracks and joints etc over /4"
wide that is applied first, then you follow up with the finish coat
applied by roller........
