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.
The Correct Way to Use an Inflatable Cofferdam
An inflatable cofferdam is an excellent alternative to a sheet pile. The inflatable dams are environment-friendly, cost-effective, and highly-efficient in controlling floodwaters. All you should do is consider the five factors discussed when considering a cofferdam.

What are Cofferdams?
Dating back to the days of Persia in 539 B.C., cofferdams have been used in construction for centuries. Cofferdams are watertight enclosures that are temporarily placed in bodies of water to create dry worksites. Today’s cofferdam may be designed with different materials, but the goal is the same: control water flow. Whether you’re building near water or preparing for a flood, cofferdams are a great alternative to sandbags.
Pro Tip: Stop spending a fortune on one-time use cofferdams. Invest in an Aqua-Barrier, the redesigned water control solution that can be reused.
Types of Cofferdams
Depending on the building project, there are different types of cofferdams to consider. Braced cofferdams are designed with single-walled steel sheet piles driven into the water, and cellular cofferdams have double-walled piles that may be filled with clay or sand. Inflatable water dams, in contrast, are made of vinyl material and use the water to create a barrier. Depending on the variable of the specific construction project, the appropriate type of cofferdam may vary from project to project.
Unlike caissons that are installed permanently in water, cofferdams are temporary structures that allow for new construction or maintenance repair. Cofferdams give construction crews the ability to perform their job without water getting in the way. The most common construction applications include:

When building a bridge or any other structure in water, a dewatering solution is crucial to completing the project successfully. All dewatering methods are essentially the same, specifically to create a dry work environment. There are, however, differences to note when examining a caisson vs. cofferdam. Becoming familiar with these terms will help you and your team choose the best solution for your next project.
Yes, there really is a difference between caissons and cofferdams. While construction novices may use the terms interchangeably, each has unique characteristics. Knowing the differences and how they apply to your construction project will ultimately improve the success of your project.
A caisson is a box-like structure that is permanently fixed within the water table of engineering projects. They are primarily used in the construction of bridges, piers, or similar structures. Depending on the size and scope of the project, there are three different caissons used most commonly.
- Open Caissons – Timber, steel, or concrete box that is open at the top and bottom of the structure. The walls are generally heavy and pumped with reinforced concrete to ensure a dry area.
- Box Caissons – Watertight boxes usually composed of timber or concrete that are open at the top. They are generally floated to the specific area and then sunk into place with a masonry pier.
- Pneumatic Caissons – Primarily used in underwater construction, these boxes are closed at the top and open at the bottom. Water is pushed out during the sinking process by using compressed air.
In comparison, cofferdams are temporary structures that are installed to divert water away from worksites. Cofferdams are most commonly used in new construction works or short-term maintenance projects of shallow bridges, piers, or boat ramps. Traditional cofferdams are filled with concrete or rock to restrict nearby water or river flow. Comparatively, inflatable cofferdams use water pumps to inflate themselves and create a temporary dam.
Pro Tip: AquaBarrier cofferdams are not only environmentally-friendly but easy to install. Save time and money by choosing a dewatering solution that your whole crew can use.
Caisson vs. Cofferdam
Not all building projects are created equal. With that being said, where a cofferdam could be installed, a caisson may not be applicable. Both caissons and cofferdams are watertight structures that can be used in the construction of submerged water areas.
The difference, however, lies within the scope of the project. Caissons are permanent structures found in the initial design construction, whereas cofferdams are temporary structures installed for necessary repairs or maintenance.

Construction building near water poses a number of challenges. Whether you’re building a bridge or constructing an office building, there is a need for reliable water control. Today, the best solution is a cofferdam. Keep your work areas dry and secure with a type of cofferdam that will meet your construction requirements.
Types of Coffer Dams
A coffer-dam can be defined as a structure that holds or guards water away from a work area. By dewatering a worksite, construction crews are able to do use their equipment and materials with better precision. To better understand the capabilities of cofferdams, consider the differences between the three most common types.
- Braced Cofferdams
- Cellular Cofferdams
- Aqua-Barrier Inflatable Cofferdam
1) Braced Cofferdams
Generally used in shallow water levels or bridge pier construction, braced cofferdams are formed from a single wall of sheet piling. Each sheet pile is driven into the water and then braced together. By creating a box around the excavation site, water can be pumped out of the enclosed interior to create a dry site.
2) Cellular Cofferdams
Reserved for circumstances where excavation size precludes the use of cross-excavation bracing, cellular cofferdams are designed with steel sheeting. By forming a watertight wall, each steel sheet pile is filled with clay or sand to provide stability against lateral forces. There are two different types of cellular cofferdams, including the diaphragm and circular type:
- Diaphragm Type – Consists of circular arcs in the inner and outer sides of the cofferdam. The cell is usually filled with sand or coarse-grained soils to weigh the sheet piles down and secure overall stability.
- Circular Type – Consists of a set of large diameter circular cells interlocked by smaller arcs placed in-between. Each circular cell is filled independently, providing greater strength against lateral pressures.
3) Aqua-Barrier Water-Inflated Dams
Unlike traditional cofferdams, the Aqua-Barrier is a water-inflated dam. Moreover, it can be used alone or together with other dams to absorb various depths of water. Instead of having to pump the water into another location, Aqua-Barrier innovatively pumps excess water into itself to provide stability. Designed with industry-grade vinyl-coated polyester, each inflatable dam will protect the area to be enclosed with durability.
Pro Tip: Use the AquaBarrier in a variety of construction projects including culverts, boat ramps, pipelines, bridges, and many others.
Reliability for Your Work Area
At the end of the day, finding reliable water control systems is crucial for construction projects to be completed safely and on time. Without a dry site, pouring concrete, driving equipment, or welding materials could become hazardous. If you have a construction project located near a body of water, choose a dewatering solution you can trust.

Is your construction site near a body of water? Whether you’re building a bridge or repairing a pipe drain, it’s crucial to have a way to remove water that is effective and accessible for your whole team. That’s the importance of the dewatering process.
What is dewatering exactly? The dewatering process is the removal of water from solid material or soil. In many cases, it’s the removal or draining of groundwater from a riverbed, construction site, caisson, or mine shaft by pumping or evaporation. For construction sites, dewatering is the first step in making sure the project will have a dry and stable foundation.
The Problem with Water
Water is one of the most powerful forces of nature. On a construction site, it can create a number of hazardous work conditions for your workers. With little notice, it can also be the cause of extensive erosion problems. Runoff water can erode the soil on a construction site causing insecure grounding, sediment buildup, and loose contaminants. Without a proper dewatering system, your construction project could find difficulty to be completed.
