Portadam Cofferdam Capabilities Video

Providing safe, cost-effective and comprehensive water management solutions since 1974.


For over 35 years, Portadam has been utilized as an effective temporary cofferdam solution providing contractors a dry work condition while saving both time and money.

Traditional cofferdam and water diversion approaches are often specified to allow the work to take place in the dry, but these can be very cumbersome – from a cost, environmental and scheduling perspective. Subsurface conditions, site conditions, site access and logistics often pose significant challenges to identifying the optimal design of a comprehensive engineered solution.

Our engineered system has been used in over 5000 water-related projects both nationally and internationally. The Portadam system has no environmental impact due to its freestanding nature. Additionally, no ground penetration is typically required, thereby minimizing subsurface risk (environmental, cost and schedule) usually associated with sheet piling. An added benefit is that dewatering of excavated material is minimized.

Flood Protection

The Portadam system can be used to divert floodwaters away from key infrastructure such as healthcare facilities, emergency response centers, treatment plants, power plants, substations, and reservoirs. The flexibility of the equipment enables quick installation on unprepared surfaces and along almost any desired line. We have a history of successfully preventing damage from flood waters.

Our rental solution provides tremendous value and eliminates the need for expensive purchases. Additionally, our rapid response approach means protection when needed.

The US Army Corps of Engineers has fully tested and vetted the system. Results of tests were so convincing that they decided to purchase and include the Portadam system in their arsenal of flood fighting tools.

Normal facility/plant operations can continue during installation. The skeletal steel framework system can be pre-installed with the liner being placed only at the final moments. The equipment is offered in various heights from 3′ high to 12′ high to allow for the desired measure of protection.

Existing levees can be raised with Portadam, which is one-tenth the weight of standard sandbag extensions and installs in a fraction of the amount of time.

Water Storage

Large volume water storage is a critical component of water management strategies.

Portadam’s proven engineered water storage system allows you to maximize your water storage capacity by nature of its versatile design.

Unlike round basins, it can be custom fit to your existing space – even if it is irregular-shaped. You will gain significant water storage volume by eliminating the empty corners left by round tanks or the empty gaps between frac tanks. There is also no need for a costly & inefficient manifold system required for multiple frac tanks or round tanks.

This system has been a key component of optimized pad designs across North America. It enables you to achieve the smallest, most efficient footprint possible to meet your large volume water storage requirements. There is no size limitation associated with this modular system, allowing it to hold an unlimited capacity. These factors make the system an economical alternative to costly earthen impoundments, large circular tanks and frac tanks.
