Road blockers, Rising Kerbs

Our road blockers and rising kerbs provide effective traffic control where other conventional barriers are unable to do so. They are ideal for maximum security sites such as government institutions, royal palaces, military bases, police stations, embassies, or airports.


Manufactured to the highest standards, our road blockers feature hydraulic drives with a quick-acting mechanism to remove the risk of “tailgating” through an access point. While we offer all standard road block sizes, we can also provide you with a custom build to best fit your road size.

How do our Road Blockers Work?

Our standard road blockers range from 2m to 5m in width and 350mm, 500mm, and 800mm in height above ground. However, we offer custom builds for units designed to fit the exact width of your roadway. Our heavy-duty durbar top plate is coated with safety markings and comes with removable access covers for efficient installation and servicing.


Road blockers are operated by a hydraulic ram with the power unit (HPU) located within an externally rated cabinet. The mechanism is encased in a galvanised sheet steel enclosure with access points for hydraulic hoses and control cables. On installation, the entire enclosure is encased in concrete to meet site ground conditions. This helps keep the mechanism completely protected from impact and tampering, for the utmost protection.

The road blocker’s push-button control comes standard, but it can be customised to suit your specific requirements. With a wide range of access control equipment such as inductive loop systems, card readers, communication equipment, and manned guard emergency systems, we have exactly what you need.


For safety reasons, pedestrians, cyclists and motorcycles are advised not to use a blocker controlled roadway, though additional safety measures can be incorporated if required. To ensure safety, a recordable CCTV system, traffic lights and safety inductive loop systems are recommended at the control point. In addition, accumulators can be specified as an option to provide an emergency quick operation option, which is popular at high-security locations.
