Evolution of Cofferdams
Cofferdams have a rich and interesting history. They have been used for water control dating back to 539 BC and have evolved and improved over time.
In 539 BC, King Cyrus of Persia used earthen cofferdams to temporarily divert the Euphrates river, allowing the capture of the city of Babylon. Babylon’s dominance ended and the rule of the Medo-Persian empire began.
The Romans used temporary wood pilings as cofferdams to build Trajan’s Bridge across the Danube river in 102 AD in modern-day Romania.
Sandbags for Water Control
Sandbags were first used during the Napoleonic Wars in the 1800’s. They were first used for protection during battle and later used as temporary dams for water control.
Steel Sheet Pile Cofferdam
In the early 1900’s a milestone in cofferdams was introduced in the form of steel sheet pile by an engineer in Germany. Larssen’s “U” shaped piling with its interlock design is still used today.
Aqua Barrier Water Inflated Cofferdam
Aqua-Barriers were introduced into the marketplace in 1996 featuring a patented internal baffle system which provides stability.
