Cofferdams are used in many industries when dewatering and water diversion are necessary. You might not realize it, but the history of cofferdams is long and fascinating and dates back thousands of years. During this time the cofferdam has evolved and improved several times.
The Evolution of the Cofferdam
Cofferdams have been around for centuries, but they haven’t all looked or worked the same. The history of cofferdams is interesting and takes us back to the Persian empire. Here is the timeline of cofferdams used throughout history and how they have advanced through the years.
- Earthen Cofferdam
- Roman Cofferdam
- Steel Sheet Pile Cofferdam
- Aqua-Barrier® Inflatable Cofferdam
1) Earthen Cofferdams
The first cofferdams were said to be used by King Cyrus of Persia in 539 B.C. to temporarily divert water from the Euphrates river, allowing the capture of Babylon. This capture of Babylon ended their rule, allowing the Medo-Persian empire to begin.
2) Roman Cofferdams
The Romans had their own cofferdam, as well, and it was made from wood pilings that they temporarily used in order to build bridges across the Danube river in 102 A. D. in what is now Romania.
In the 1880’s, during the Napoleonic wars, people used sandbags to control water. Initially, these bags of sand were used for the protection of the troops during battle, but eventually, they were used as temporary dams and water control.
4) Steel Sheet Pile Cofferdams
After a hundred years of using sandbags, a milestone in cofferdams was introduced through the steel sheet pile cofferdam. In the early 1900’s, a German engineer came up with an interlocking design of ‘U’ shaped steel to help control water. This interlocking steel cofferdam design is still being used today in some countries.
5) Aqua-Barrier® Inflatable Cofferdams
Fast forward to 1996 and the invention of the Aqua-Barrier® cofferdam. This inflatable cofferdam features a patented internal baffle system that not only provides stability but the ability to use on any terrain, too. The Aqua-Barrier® is vastly more effective and efficient than outdate sandbags, and is also more environmentally friendly, too.
Modern Uses and the Cofferdam
The modern Aqua-Barrier Inflatable Cofferdam is the essential tool for a variety of dewatering projects, such as building and repairing boat ramps, pipeline construction projects, water park maintenance, shoreline restoration, flood protection, and more.

While a dry worksite is essential for many construction and repair projects, there are some cases where it is not feasible to completely cut off the water flow. Sometimes, a project requires you to completely block off the water for the duration of your project, while others need a diversion to keep the water flowing smoothly while you work. Here are some helpful tips for successful water diversion on your next project.
Diverting Water for Construction Projects
Often, construction projects require work done across streams, rivers, or similar small bodies of water. Since these bodies of water cannot be fully blocked, water must be diverted to maintain a healthy flow. Some typical projects requiring water diversion are:
About Water Diversion
Sometimes a diversion is necessary for construction to ensure an isolated, dry project area. In some cases, water is temporarily rerouted in order to prevent or minimize contamination of clean surface waters. Water diversion also provides an effective method of sediment control. With water diversion, work zone sediment is prevented from entering the body of water, which is especially crucial when dewatering stormwater areas.
Best Method for Water Diversion
Working in water is one of the most complex construction scenarios imaginable, and an Aqua-Barrier® Cofferdam should be an essential component of your water diversion project. Easily deployed and completely portable, Aqua-Barrier® can be used in a variety of configurations to divert water, creating a dry work environment.
Construction Projects & Water Diversion
Inflatable bladder dams, like the Aqua-Barrier®, have quickly become the leading method for water diversion and dewatering in construction. They are easy to deploy, effective, and environmentally friendly. Consider investing in a water-inflated bladder dam for your future dewatering and diversion projects.

Doing any kind of construction underwater requires the construction site to be dewatered beforehand. Your workers need a dry, stable environment to complete the repairs or new construction. Sometimes, though, a project may require water to also be diverted.
Types of Projects that Require Dewatering and Diversion
Many projects require water to be removed from the worksite for a safe, dry construction environment. Temporary cofferdams have conventionally been filled with earth and rock, though sometimes concrete or sheet pilings are used. However, today water-filled inflatable bladder dams have become the industry standard for dewatering construction worksites.
At times, the worksite may need to be dewatered and additional water may need to be diverted. This may include projects that involve bridge repair and construction, dredging, chemical spills control, fish habitat protection, environmental remediation, shoreline restoration, pipeline crossings, construction site dewatering, levee repair and construction, wetland management, construction of pumping stations, irrigation canals, and other manmade structures, and water storage.
All About Diversion
Sometimes diversion is necessary in construction to ensure an isolated, dry project area. In some cases, water is temporarily rerouted in order to prevent or minimize contamination of clean surface waters. It’s also instrumental in providing an effective temporary water barrier to allow for easier dredging of smaller waterways such as ponds and canals. Diversion provides an effective method of sediment control. Work zone sediment is prevented from entering the waterbody which is especially crucial when dewatering storm water. Finally, water diversion allows for maintenance of upstream fish passage if an area will be affected for an extended period of time.
The Dewatering Standard
Inflatable bladder dams have quickly become the leading method for dewatering in construction. They are easy to deploy, effective, and environmentally friendly. Consider investing in a water-inflated bladder dam for your future dewatering and diversion projects.

Working on a construction gig that requires you to dewater a worksite? As you know, not all dewatering jobs are the same. Sometimes you can completely block off the water for the duration of your project and others you will need to create a diversion to keep the water flowing smoothly while you work. Often dewatering projects require cofferdams to be installed bank-to-bank across streams, rivers, or similar small bodies of water. Since these bodies of water cannot be fully blocked, water must be diverted to maintain a healthy flow.
Water Diversion for Streams, Rivers, and other Bodies of Water
Hydrological Solutions has had many years of success with using diversion pipes and by-pass pumps along with Aqua-Barrier® cofferdams to safely redirect water at construction sites in or near streams, rivers and other bodies of water.
Used by Contractors All Over the World
Contractors and project managers love the versatility of the Aqua-Barrier® cofferdam system and continue to successfully deploy the water-inflated dams with diversion for many projects all over the world. This combo comes in a variety of sizes to fit the needs of different construction sites. Cofferdams and diversion pipes can also be set up in numerous formations depending on the shape of your worksite.
Most Cost-Effective Solution for Dewatering with Water Diversion
Quick and easy to deploy, the Aqua-Barrier® cofferdam system has saved many contractors both valuable time and money. Because time is money in the construction industry, this has quickly become the most cost-effective dewatering solution with water diversion in the world.
