The new inner tube should be filled just like the original. 

Any excess plastic material should be either cut off or unrolled. In this case, there was so little material left that it was unrolled and folded over.

The excess plastic will now be rolled up in the end of the AquaDam® as it is re-rolled. The original 4" x 6" beam that the dam came rolled on is used for this purpose.

The end of the AquaDam® is rolled up until it is out of the way.
