The C122 is a model within our Heavy Duty product range, embodying the same stable, robust, and durable construction as the other flood barriers in the series. As the very first Heavy Duty model produced by Geodesign Barriers, the C122 has been at the core of our DNA, with over 20 years of proven use in the field. Its flexible design makes it particularly well-suited to handle complex and challenging flood protection scenarios where adaptability is key.

Introducing the C122 Heavy Duty flood barrier, the original model in our Heavy Duty series and the foundation of Geodesign Barriers’ innovative flood protection system. Like its successors, the C122 features a triangular metal support that folds out and connects via two rods. Aluminum sheets are suspended from the rods, and a laminate-coated high-density polyethylene membrane is draped over the structure to form a ground-sealing surface.
The C122—like all Geodesign Barriers—can be deployed without tools, machinery, or groundwork. Once water arrives, it pushes the barrier into the ground, making it entirely self-anchoring.
As the first Heavy Duty barrier we produced, the C122 has over 20 years of proven field use and remains a flexible, reliable solution for complex and demanding flood protection challenges. With its robust design and 122 cm dam height, it offers unmatched versatility for a wide range of scenarios.

Our step-by-step instructions are designed to guide you through the process of setting up your system quickly and easily. Even if you're new to the C152, our instructions are straightforward and easy to follow.
While we're confident that anyone can set up the C152 using our manual, we do recommend training and consultation for the best possible outcome. These additional resources can help you optimize your setup and ensure that everything runs smoothly.
Place the C152 Barrier Supports 122 cm apart. Use Link Bars to gauge the distance.
If installed on concrete
Prepare installation of Concrete Anchor. Drill a hole using a Hammer Drill.
If installed on concrete
Screw on the Concrete Anchors into the ground. Leave a distance of 1.5 cm between top of the anchor and the bottom beam of the C152 Barrier Supports.
Errect the C152 Barrier Supports. ❶ Lift the front beam up and ❷❸ unfold the support beams. Slide the inner support beam until it rests against the security axis.
Secure the C152 Barrier supports upright position with the Snap Lock. ❶ Push the protruding rods outward, ❷ then upward, ❸ until they pass through the cut-out.
❶ Insert the Z-lock on the Link bar into the keyhole cutout on the front beam. ❷ Lower it until the Z-lock rests at the bottom of the cutout.
Mount the 1071 Aluminum Panels by ❶ sliding the triangular cutout over the Link Bar. ❷ Lower it until the panel hangs on the protruding part.
Roll out the 4.5 m wide Geodesign Poly Membrane and secure with one Sealer Clip per section, along the top edge. Ensure that there is between 15-20 cm overlap at the back of the barrier.
Connect the chain lengths with karabiners and place them along the membrane's outer edge. ❶ Wrap or lay the chain on the membrane, ❷ thread a cable tie through the pre-punched holes, ❸ and secure the chain.
If installed on concrete
Seal the poly membrane to the ground by applying 20 cm wide sealing tape over both the chain and the membrane edge.
Hang the garland chain on the inclined part of the barriers. Fasten the chain to the C152 Barrier Supports using the carabiner hook.
Adjust the Sealer Clips as water enters the barrier to relax the Poly Membrane. Gently step on the membrane to squeeze out air pockets.
Installed and self-anchored as rising water presses the barriers to the ground.
