- Canal Crossing for Bridge Repair
Brentwood, CA (2004)
Page 1 of 5
An 8' x 100' AquaDam® was used to block off this runoff channel so
that a bridge crossing could be constructed immediately downstream.
The AquaDam® was started at the top of the bank, rolled down to the flat
area, and then crossed the lower portion of the channel. Water depth
was only 18 inches.
Since there was virtually no water flow, no head pressure needed
to be maintained inside the AquaDam® during installation. It was
allowed to unroll of its own accord while filling.
Make sure you start the AquaDam® high up the bank, and end high up the
bank on the opposite side.
The sides of this AquaDam® were folded in, and it spread apart
as water pressure built inside. Notice that everybody seems to be standing
around. On an installation like this, there is very little to do other than
man the pumps.
Notice how high the AquaDam® was started up the bank, and how wide it is
compared to the unrolled section. The AquaDam® was installed over the top
of the grass, even though some brush was removed by hand.
