An inflatable cofferdam offers an efficient and effective way of controlling invasive water during floods. So, if you’re running a project that requires dewatering solutions, consider the inflatable cofferdam. We’ll show you how to use it. Keep reading to learn more!
What are the steps to using an inflatable cofferdam?
Inflatable cofferdams have several applications. In most cases, it provides access to underwater areas during construction and maintenance. You can also use it for hazardous liquid containment and sediment retention in a sensitive work area.
Here are the factors to consider when using a cofferdam for dewatering solutions.
- Understanding Water Levels
- Obtaining Necessary Permits
- Hiring Experienced Contractors
- Removing Debris From The Site
- Determining the Type of Installation
1) Understanding the Water Levels
Water levels usually fluctuate from season to season. So, you need to review the timing of your project and plan accordingly. Consult the U.S. Geological Survey to figure out fluctuations in water level at the site and determine the best timing.
2) Obtaining Necessary Permits
Some of the essential permits you’ll need for a cofferdam project include contamination concerns, turbidity requirements, right-of-way restrictions, and time constraint permits. Thankfully, a project engineer can help you get the permits for dewatering solutions.
3) Hiring Experienced Contractors
Working with a contractor who has experience in dewatering construction can help you save time and money. Such contractors know what to do when invasive water floods the work area. Typically, they will deploy a water-inflated flood barrier for flood protection.
Pro Tip: It’s worth knowing the product specifications and making sure you meet dam size requirements before implementing the inflatable cofferdam.
4) Removing Debris From The Site
It’s imperative to remove all the surface debris that can puncture the water barrier’s plastic membrane. Ensure that the area you’ll install the flood barrier is free of sharp rocks, stumps, and rebar. If you don’t remove the debris, the following might happen:
- Inability to keep the water barrier inflated if there’s a large puncture
- Loss of inflation due to the small leaks in the barrier
- Reduced stability of the flood barrier
5) Determining the Type of Installation
There are three basic water barrier installation types, including dry surface installations, static-water installations, and dynamic water installations.
- Dry Surface Installation: The barriers get deployed in areas with no water in anticipation of flooding. You’ll simply roll the barriers and inflate them.
- Static-Water Installation: The barriers get installed in areas with non-moving water. The barriers float on the water’s surface during installation.
- Dynamic Water Installation: Water barriers get positioned on moving water by controlling the units’ ends using hydraulic equipment.

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.
Top Uses for an Inflatable Cofferdam
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.
- Boat Ramps
- 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.
Installing the Aqua-Barrier
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.

According to OSHA, between 2011 and 2017, there were 79 fatalities and over 3070 non-fatal injuries among gas and pipeline workers. And while pipeline construction workers are at a higher risk of accidents, the good news is most are preventable when proper construction safety tips are practiced.
Staying Safe: Pipeline Construction Industry
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
- Constant Awareness
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.
