Key Features and Benefits of our Robust Demountable Flood Barriers

Customisable Dimensions

Each log section of our flood barriers is customisable based on your specific design criteria and storage capacities. This ensures that the barriers meet your unique project needs.

Optimised Design

Our flood barriers are designed with precise engineering criteria, considering length, pressure, and other stress factors. Refer to our detailed stress diagram for our different profiles to select the best option for your project.


The cost of our demountable flood barriers is influenced by the number of supporting I-beams required. By opting for longer log sections, you can reduce the number of I-beams needed, resulting in a more economical solution without compromising on protection. Additionally, our barriers are maintenance-free, ensuring long-term savings and hassle-free ownership.

Technical Specifications and Robust Support

Our engineers will evaluate the stress applied to the supporting beams and soil type. Collaborating with your civil engineering team, we determine the appropriate dimensions for the foundation, ensuring a solid and reliable installation. Our robust system is designed to offer a very low leak rate of less than 3 liters per hour per square meter, providing exceptional performance and reliability.

Easy and Quick Installation

Our demountable flood barriers are designed for quick and efficient installation. Each I-beam fastens onto anchor housings embedded in concrete foundations using our innovative quick-rail-set system, facilitating a streamlined setup process and ensuring the barriers are securely in place. Installation is straightforward and quick: 5 minutes per square meter. The lightweight materials allow for easy handling and setup by personnel without the need for heavy machinery, ensuring a hassle-free installation process that provides you with reliable flood protection swiftly and efficiently.

Sustainability & Corrosion-Free

Designed to withstand contact with river water, seawater, and other types of water, our barriers are guaranteed to be corrosion-free for a minimum of 20 years.

  • Log Section Placement for Demountable Flood Barriers: Install log sections according to the designed length and pressure specifications.

Mechanical Resistance: Robust Engineering Standards

All our equipment is designed and manufactured according to:

  • The calculation and manufacturing rules for “metal frame” elements in aluminum as dictated by D.T.U. (Documents Techniques Unifiés) and AL 76, with a standardised safety coefficient.
  • Assembly procedures by TIG/MIG welding according to EN NF 287-2 standards, using stainless steel AISI 316 fasteners.

Sealing Joints: Superior Sealing Technology

  • The geometry of the joints is integrated into our assembly range to minimize the risk of leakage.
  • The quality of the EPDM material and the manufacturing process by extrusion ensure exceptional resistance of the joints against:
    • Unintentional and repetitive friction.
    • Accidental tears (e.g., during handling).
    • Corrosion from contact with river water, seawater, or other types of water (e.g., wastewater).
    • UV-induced aging that deteriorates their mechanical properties.
