The work area is nearly fully dewatered, an outstanding demonstration of AquaDam®'s effectiveness in water control!
Workers continue to de-water the site to create a dry workspace for beginning earthmoving operations.
This image clearly illustrates the extent of the erosion and damage to the culvert storm drain system.
This head wall and culvert set has begun to wash out into Perdido Bay, the larger body of water visible in the background.
This view captures the closed end of the 8ft tall single closed-end (SCE) AquaDam® at its ending bank. When fully filled, an 8ft tall AquaDam® spans 17ft in width, with its outer perimeter positioned directly against the seawall on the right.
This image illustrates the height to which the workers constructed the starting bank for the AquaDam® installation.
Workers are de-watering the area with a pump they've positioned within the workspace.
Air trapped during the AquaDam®'s filling process forms the large bubble visible in the far left corner. Workers can easily walk this air, from the pumps, toward the open end and fill-tubes to release it.
Because forming a reliable seal against the stone seawall would have been challenging, the AquaDam® was instead started and terminated on native ground to ensure a more effective seal.
From the bank, we're looking at the closed end of the 8-foot tall AquaDam®. There was still some extra material on the beam it was shipped on, highlighting the benefit of having more length than needed.
Here, the water of Perdido Bay is being effectively held back by the 8ft tall AquaDam®. Note the substantial water level on this side of the AquaDam®, highlighting its capacity to withstand significant hydrostatic pressure.
In order to properly install a SCE AquaDam®, it is essential to have a starting bank that maintains the open end at a higher elevation than the full height of the AquaDam®. The open end and fill-tubes of an SCE AquaDam® must remain elevated above the dam's full height along its designated path. The AquaDam® will only reach its maximum height at the lowest point along its designated path.
A starting bank, built from sand fill and large stone, was necessary to elevate the AquaDam's® open end and fill-tubes above its full height, measured from the lowest point of the dam's path. Remarkably, the AquaDam® was installed in only four hours.
An 8-foot tall single closed end (SCE) AquaDam® created a de-watered area in a horseshoe or "U" shape in Pensacola, Florida, enabling the repair of concrete culverts and a head wall stormwater drain.
