Road blockers and rising kerbs are a powerful solution for commercial sites that need more than a standard barrier or gate. They provide a strong physical defence against unauthorised vehicle access while allowing controlled entry for approved users.
AGD Systems supplies and installs automatic road blockers and rising kerbs for commercial, industrial and public sector sites across the UK. Suitable for manned and unmanned entrances, they are available in a range of widths and security heights, with hydraulic operation, access control integration and safety features to suit the demands of busy working environments.
For some sites, rising security bollards may also be a suitable alternative or complementary solution, particularly where pedestrian access needs to remain open or where more flexible perimeter protection is required. AGD Systems can advise on the most effective arrangement based on your entrance layout, traffic levels and security risk.
Road blockers and rising kerbs for commercial vehicle security
Road blockers and automatic rising kerbs provide a high level of vehicle access security for commercial and industrial sites where a boom barrier alone is not enough. They offer a strong physical stop for unauthorised vehicles while allowing controlled access for approved users.
AGD Systems designs, supplies and installs automatic road blockers and rising kerbs across the UK. We help you choose the right blocker width, height and control method, then deliver a complete installation with commissioning, safety checks and ongoing support.
A rising kerb is a hydraulically operated road blocker that lifts from a recessed housing in the ground to restrict vehicle access, then returns to sit close to the road surface when lowered so normal traffic can pass. Compared with a simple rising arm barrier, a road blocker provides a much stronger physical barrier and a clear visual signal that the entrance is protected.
Road blockers and rising kerbs are typically used:
Automatic road blockers and rising kerbs can be specified for a wide range of sites, including:
If your site experiences repeated unauthorised vehicle access, or you simply need a tougher solution than a parking barrier, a road blocker or rising kerb can be a highly effective option.
AGD road blockers and rising kerbs are built for demanding environments, using a welded steel frame with a heavy‑duty top plate and a hydraulic power pack for smooth, controlled movement. A programmable logic controller manages operation and coordinates access control inputs and signalling such as traffic lights and warning devices.
Vehicle detection loops and other safety devices can be integrated to help prevent the kerb or blocker rising when a vehicle is present in the danger area. During specification we will confirm the best safety strategy for your site, including sensors, lights and audible warnings where appropriate.
Road blockers and rising kerbs can be specified with an emergency lowering function so the entrance can be made safe in the event of a power cut. For sites that require emergency access at all times, we will design the system so that the fail‑safe position and manual overrides match your operational and safety requirements.
Road blockers and rising kerbs are available in a range of widths to suit different entrances, typically from around 2.0 metres up to 5.0 metres for single‑lane and wider access routes.
Different blocker heights can be specified to match the level of restriction required, for example:
We will recommend the correct size and height based on the vehicle types using the entrance, expected traffic flow and your security risk profile.
Road blockers and rising kerbs can be integrated with the same access control systems used across your site so that operation is familiar and efficient for staff, visitors and contractors. Typical options include:
These can operate alongside safety devices and vehicle detection loops to support controlled entry, automatic exit where appropriate and reliable daily operation. Road blockers and rising kerbs can also be linked with other elements of your traffic control and security system, including rising bollards, barriers, automatic gates, CCTV and building management systems.
For many commercial and industrial sites, there is a choice between road blockers, rising bollards and other vehicle control products. As a supplier of all three, AGD Systems can recommend the most suitable arrangement based on your layout and risk level.
In many cases, road blockers, rising kerbs, rising bollards and barriers are combined to create layered perimeter protection – for example, bollards across a frontage with a rising kerb or road blocker protecting a high‑risk loading bay or back‑of‑house service route.
Road blockers and rising kerbs are specialist products that require correct civil works, drainage provision and careful commissioning. AGD Systems provides a complete survey and installation service so the system is specified correctly and works reliably in real‑world UK conditions.
Planned servicing is recommended to maintain performance and safety over the long term. AGD can provide ongoing maintenance support, including checks of hydraulics, fixings, control settings, traffic light sequences and safety devices. This helps ensure dependable daily operation and supports your compliance obligations for automated vehicle control equipment.
If you need a robust vehicle access control solution and want to explore whether a road blocker, rising kerb or rising security bollards are right for your site, speak to AGD Systems. We will survey the entrance, recommend the correct specification and combination of products, and provide a clear quotation for supply, installation and commissioning.
Rising Kerbs and Road Blocks
Do rising kerbs lower during a power cut?
Yes. AGD rising kerb systems include an emergency lowering facility so the kerb can be lowered in the event of a power failure, helping maintain safe access when needed.
What groundworks are required for a rising kerb installation?
A rising kerb is installed into the driveway surface and needs proper excavation, a stable foundation, and correctly planned ducting/cable routes. A site survey is the best way to confirm the correct civil works and positioning for safe, reliable daily operation.
What access control options can operate a rising kerb?
Rising kerbs can be operated using common access control methods including proximity cards, remote fobs, token acceptors, keypads and intercom systems, typically working with inductive loop sensors to support safe operation and correct close function.
