- Boat Ramp Replacement
Little Creek Naval Base, Norfolk, VA (2001)
Page 1 of 21
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.
