Understanding the history of cofferdams directly relates to how dewatering solutions are used today. From bridges to canals, the introduction of cofferdams in construction provided a solution for building structures near large depths of water. With the varied uses of cofferdams, we now have the ability to create dry worksites quickly and efficiently for any construction project.
If you’re building or handling equipment near a body of water, it’s crucial for you to control the flow and location of the water. Without a proper dewatering tool, your worksite could suffer from erosion, damage, and in severe cases, complete destruction. Cofferdams can be used in a number of applications, but the following five are some of the most common in construction.
Pool & Waterpark Maintenance
Despite the force of water currents, cofferdams have been used quite often in the construction of bridges. By establishing an enclosed area within the water, builders can build or repair the road connection without fear of flooding.
Digging underground to install large pipelines can create a myriad of issues, but water doesn’t have to be one of them. With a cofferdam, you can create a secure single wall against water from the ground up. Whether you’re installing a new pipeline or repairing an existing line, the cofferdam is a perfect solution for keeping water at bay.
3) Boat Ramps
When building a boat ramp, there’s a great need for removing water from the site location. Cofferdams can be used to create a dry worksite to fit the needs of your project. Inflatable cofferdams are an excellent solution for flood protection.
Pro Tip: Save time and money by using an Aqua-Barrier Inflatable Dam for your next boat ramp project, with the capability to work in water up to 6 feet deep.
4) Pool & Waterpark Maintenance
To save time and conserve water, a temporary cofferdam is a great solution for pool or waterpark repairs. AquaBarrier, in particular, is a water-filled cofferdam that is installed in your pool to create a dry work area without having to drain any water.
Unlike most construction projects, canals and culverts are designed with water control in mind. That being said, necessary repairs on culvert concrete or surrounding areas can be weakened if the water isn’t routed in another direction. Cofferdams provide a way for construction workers to get their job done without having to worry about water getting in the way.
Dewatering Solutions Designed for You
Compared to doubled walled cofferdams or rock-filled sheet piles driven into the ground, the AquaBarrier is an affordable solution for projects requiring dewatering. With various dimension sizes and easy handling, it is a water control solution recommended in many construction applications.

An inflatable cofferdam such as the Aqua-Barrier provides a simple, low-cost way to guard against excess water. The barrier can be installed in anticipation of a flood, as a dewatering method, or to help curb the flow of water. Today, we’ll be looking at the proper cofferdam installation methods for all three primary scenarios.
The Aqua-Barrier provides excellent protection against flood waters or water around a construction site. However, as with any type of cofferdam, it must be properly installed to work correctly. The three scenarios in which an inflatable cofferdam is usually deployed are as follows:
Dry surface installation
Static water installation
Dynamic water installation
1) Dry Surface Installation
To install the Aqua-Barrier on a dry surface, simply unroll it around the area you want to protect and inflate the cofferdam with water to its desired height. That’s it!
Installing the cofferdam on a dry surface is usually done as a preventive measure if flooding is anticipated. For particularly nasty floods, it’s recommended to inflate the Aqua-Barrier to its maximum height of about six feet. Don’t let even a drop of water get through.
Pro Tip: Smooth out the area your Aqua-Barrier will lie on as much as possible. While the vinyl is strong, obstructions could be problematic.
2) Static Water Installation
You would use this installation method to install the Aqua-Barrier in a body of stagnant water, such as a swimming pool. Unroll the Aqua-Barrier across the surface of the water and float it to its desired position. Once the cofferdam is in place, begin pumping in water. The cofferdam will inflate downwards into the body of water and provide a sturdy barrier.
For more details on installing the Aqua-Barrier in static water, check out these instructions.
3) Dynamic Water Installation
For construction projects such as pipeline repair, you’ll have to install the Aqua-Barrier in moving water. Start by positioning one end of the cofferdam in place with heavy equipment, like a backhoe, and anchor the other end to the shoreline. Inflate the bladder from the flowing water until it’s sufficiently blocked and you can begin work.
Using an Inflatable Cofferdam Properly
An Aqua-Barrier is the quickest, safest, and most cost-effective way to ensure that your property stays flood-free and your construction projects aren’t overrun with water. If you take the time to properly install your bladder dam, you’ll never have to worry about leaks or flooding.

Due to exceptionally heavy equipment, terrain issues, suspended loads, and many times inexperienced workers, pipeline construction workers have an increased risk of injury. To prevent accidents and keep everyone on the worksite safe, follow these six pipeline construction safety tips
Company Culture of Safety
Ongoing Safety Training
Personal Protective Equipment
Safe Excavation Procedures
Heavy Equipment Safety
1) Company Culture of Safety
Above all, safety trickles down from the top. Leaders need to create a culture of safety and set it at top priority. Everyone from the newest recruit through the CEO needs to have a safety first mindset. Leaders need to constantly communicate the importance and need for safety and make sure safety measures are always being implemented.
2) Ongoing Safety Training
Ongoing pipeline construction safety training needs to be a regular part of your company’s safety culture. By holding ongoing training classes, safe habits can be reinforced and new safety techniques and procedures can be learned.
3) Personal Protective Equipment
Pipeline workers should always be wearing their personal protective equipment, such as heavy steel-toed boots, eye protection, gloves, hard hats, or whatever else is needed to keep workers safe from harm.
4) Safe Excavation Procedures
Pipeline workers need to practice safe excavation procedures. Make sure they call to verify all underground utilities are marked prior to digging and also supply them with the best tools for excavating. For example, if working in an area that requires dewatering, don’t waste time on cumbersome sandbags that can cause back pain, opt for an inflatable cofferdam that can be set up quicker and safer.
5) Heavy Equipment Safety
Operators who work with heavy equipment need to be properly trained. Make sure they read the operation and maintenance manuals for each piece of equipment they work on. Before getting on a machine, they should already know how to properly use and operate the tool.
6) Constant Awareness
Many times, injuries happen because people just aren’t paying attention. Avoid slips, falls, and other accidents by always being aware of your surroundings. If you see debris laying in a walking path, clear it out of the way to help others from being injured, too.
Pipeline Construction Safety
When your workers feel safe, they are more productive and overall output is of higher quality. Go beyond normal safety standards and keep these higher standards enforced. By following the above tips, you can help make your pipeline construction sites safe and lower (if not remove) incidents of injury and accidents.

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:
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.
