Fantastic job AquaDam®!

On the right side of the image, the starting bank for one of the SCE AquaDams® is visible. Proper installation of an SCE AquaDam® requires a starting bank that positions the open end and fill-tubes at an elevation higher than the dam’s full inflated height. This elevation ensures that the open end remains above the maximum water level along the entire deployment path. Notably, an AquaDam® will only achieve its full height at the lowest elevation point along its path, due to the principle of communicating vessels and internal water pressure distribution.

This image illustrates the water level differential on either side of the AquaDam®, highlighting its effectiveness in creating a stable, dry work zone. To enhance structural integrity and prevent shifting under hydrostatic pressure, workers placed fill material along the inner perimeter of the AquaDam® for additional support.

The installation of all three AquaDam® cofferdam systems was completed in six days, enabling timely commencement of pier work within the dewatered zones.

Several high-capacity pumps were utilized both to initially fill the AquaDams® during installation and to maintain de-watered conditions within the isolated work areas throughout the project duration.

This image shows one of the three 6ft tall single closed end (SCE) AquaDam® cofferdam systems fully deployed and functioning as intended. The cofferdam has successfully isolated the work area from the Fox River, allowing excavation and construction equipment to operate in dry conditions without introducing sediment or turbidity into the river.

Three separate cofferdam systems were constructed using multiple 6ft high, 13ft wide, and 100ft long single closed end (SCE) AquaDams® to facilitate dry working conditions for pier upgrades on the Highway 30 Bridge over the Fox River in Montgomery, Illinois. Each cofferdam was configured in a horseshoe or “U”-shaped layout, effectively isolating individual work zones around the piers. The cofferdams diverted river flow away from the designated work areas, enabling construction crews to perform the needed construction on the bridge piers in a de-watered environment.
