Cofferdams for Construction
Cofferdams for Flood and Construction Dewatering
A cofferdam is a temporary structure extensively utilized in construction, primarily for two key purposes: dewatering and flood protection. In construction, cofferdams are deployed to create dry, controlled workspaces within submerged or waterlogged areas. They play a crucial role in projects like bridge construction, pipeline installation, and foundation building by excluding water and enabling safe and efficient work.
Additionally, cofferdams serve as an essential tool for flood protection, effectively stemming the ingress of rising floodwaters to safeguard properties, infrastructure, and communities from potential damage and deluge during flood events.

Cofferdam Features
Cofferdams feature several essential attributes like their ability to create a temporary, watertight enclosure in submerged areas, ensuring a dry and controlled workspace for underwater tasks. Also, they can be quickly installed and effectively dewatered, especially when utilizing a cellular cofferdam. Additionally, they are often reusable and designed for durability, making them a cost-effective solution for excavation and other applications, especially when filled with soil. Other Cofferdam features include:
- Crafted using multiple tiers of industrial-grade vinyl-coated polyester
- Includes floatable fill caps and drain caps for your convenience, particularly in sheet pile cofferdams
- It incorporates a specialized internal baffle system to enhance stability
Cofferdam Benefits
Cofferdams offer several advantages in flood barriers and construction projects. They create dry workspaces in underwater or submerged areas, enhancing safety and efficiency while managing lateral forces They are also cost-effective and save time, reducing project expenses, especially when cellular cofferdams are used for construction. With their versatility and ability to control water flow, cofferdams are crucial for various applications, from bridge construction to pipeline repairs, ensuring quality work in challenging aquatic environments. Other Cofferdam benefits include:
- Can be rapidly installed by just one or two individuals when using types of cofferdams
- Leaving no mess behind
- Offers complete flood protection through overlapping sections and is easily repairable, ideal for use with steel sheet piles
- Effectively extending the barrier's lifespan

Cofferdam Uses and Installation
These Flood Barriers offer quick and easy installation. All you need to do is unroll them and fill them with a hose, ensuring proper lateral support with a cofferdam. Compared to alternative flood barrier styles, they can be deployed 3 to 5 times faster and are engineered for robustness, allowing for approximately 10-15 uses in various conditions, including around embankments. Protecting your property from the perils of flooding has never been more crucial. With these specially crafted water-inflated dams, you can encircle your premises more rapidly and with fewer personnel than traditional methods like sandbags or other flood protection barriers, enhancing the effectiveness of cellular cofferdams. Cleanup is also significantly more efficient, and they conveniently fold up for compact storage and transport. For additional information on cellular cofferdams, please refer to the Instruction Manual (pdf).

Other Dewatering Products
Is the cofferdam not the dewatering product you were looking for? Maybe you were searching for a completely different type of product. For other dewatering options, including cellular cofferdams, see: Dewatering Products.
We also carry other sock-like erosion control devices and products for your jobsite. The silt sock, also known as the
compost filter sock for use with cellular cofferdams is used for perimeter filtration and erosion control. The Ultra filter sock
is also an erosion control product used for filtration around storm drains. Both erosion control devices are used for filtration and perimeter control.
