Project overview: A 16' high AquaDam® was needed to control 10 ½' of water at high tide. Removal of the old boat ramp was completed after the site was cofferdammed with steel sheet-pile, which failed before the new boat ramp could be poured. Further sheet-piling was prohibitively expensive, so the U.S. Navy called AquaDam®.

This picture shows the end of the open-ended AquaDam®. It is being inflated with air using two 8" blowers. You can clearly see the two white inside tubes surrounded by the white outside tube.

The AquaDam®'s height (when inflated with air) was approximately 20'. The outside tube has a circumference of 80' when inflated.

This unit was 350' long. In the middle is a red 96' long "band" for reinforcement.
