Eco - Dam technical information

The Eco-Dam is a water-filled barrier fabricated from High Tensile European produced PVC and manufactured using Computer Controlled High Frequency Welding Techniques. This ensures structural strength of the flood defense system, as well as both water proof and gas-tight seams. 

It consists of two sections separated by an internal partition. This locks into place when the barrier is exposed to uneven water pressure, as demonstrated by the diagrams below. The patented design ensures stability by preventing rolling, whilst allowing the water to move freely inside.

Each Eco-Dam has fill ports and drains ports with an overflow outlet on the top. It also has lifting handles on each end to assist with deployment.

Eco - Dam Benefits

There are many benefits to the Eco-Dam that make it an effective and efficient alternative to more traditional methods of flood defence systems such as sandbags.

  • Easy to use
  • Can be deployed in less than 10 minutes with the use of a pump
  • Minimal storage required
  • Reusable
  • Recyclable
  • Cost effective to purchase and use
  • Versatile
  • Overlapping modular design that can afford protection to large areas.
  • No extensive clean up required

Below is a direct comparison between the use of Eco-Dam and sandbags:-

Eco- Dam Uses

Flood Protection

One of the main uses of the Eco-Dam is for Flood Protection. During the recent floods, many homes were badly affected, including those in and around Winchester. As seen in the photo, 2 Eco-Dams were deployed at this property to prevent flood water entering the house. Once quickly deployed the barriers remained in situ until the floods subsided. They were then easily stored, with no clean-up required, ready for the next use.


Here the Eco-Dam served as a cofferdam to enable river maintenance and inspection. After the collapse of a sandbag wall, the Eco-Dam was deployed in less than 10 minutes and immediately prevented further erosion of the river bank. The client was very pleased with the product and mentioned how 'no other dam met their standards'.


The Eco-Dam can also be used to create large reservoirs. At Long Cross Studios 4 24m long barriers were used to create a 24 sq.m reservoir used for special effects. By taking advantage of the overlapping modular design the barriers were positioned in a square directly on concrete and were able to hold 40 tons of water.

As demonstrated by these examples, the Eco-Dam is a versatile product that can suite a variety of requirements. In regards to flooding, the Eco-Dam provides excellent community protection making it an asset to local authorities and resiliance groups. It is also suited to anywhere where it is vital to keep infrastructure and land free from flood damage. Such as construction sites, logistics warehouses, farms, retail outlets and hospitals. Furthermore, it would enable those in the facilities management industry with a new service to offer their clients.

The Eco-Dam is also effective during oil spills by preventing and containing further contamination.
