Sitewall Barrier
Heavy-duty water-filled perimeter protection
The Sitewall Barrier is a robust water-filled barrier designed to create secure, continuous perimeters around construction sites, utilities, events, and pedestrian routes. Its primary role is to provide safe separation between work zones, traffic, and the public — ensuring professional boundary control wherever it’s deployed.
Manufactured from UV-stabilised HDPE, Sitewall combines durability with ease of handling. At just 15 kg empty, it can be positioned quickly by one person, then filled with water or sand up to 300 kg for heavy-duty stability. This makes Sitewall both highly adaptable and reliable in exposed environments.
The interlocking design allows units to form tight 90° corners with no gaps, enabling clean, tamper-resistant barrier runs. Sitewall is also stackable for efficient transport and storage, and can be fitted with mesh fencing panels for additional height, security, and crowd control.
