When it comes to traffic and site safety, robustness is key. The DEFENDER50 water-filled barrier delivers exactly that. Designed to handle demanding conditions, it offers proven crash protection and the kind of flexibility that sets it apart on today’s worksites.

The DEFENDER50 has been rigorously crash tested to BS EN 1317 standards, achieving containment level N1, and it’s the first in its class to be tested with full fence panels attached. During testing, it withstood impacts at around 50 mph, remaining stable and secure within the CEN evaluation zone. There was no vehicle breach, no rollover, and no cabin intrusion, earning it a top-tier Impact Severity Rating of A.

This makes it an ideal choice for high-risk locations such as motorways, urban construction zones, and rail infrastructure projects, anywhere reliable vehicle containment is critical to keeping people and property safe.
