This AquaDam® is from a different batch than the others, and has a black
inner liner instead of clear liner. It is partially unrolled in preparation
for attachment just like the previous units, with one worker using his body
weight to help the others pull.
The holes in this collar are not precut, so they are carefully cut out
using a utility knife. 8' high AquaDams®, like the ones used here, require
a hole approximately 6"-8" in diameter. They should be about 4' apart,
placed just in back of where the installed AquaDam® ends.
