Rising kerbs are less common than rising bollards and barriers, but in the right application they remain a highly practical solution for controlling vehicle access. They are particularly useful where you want a strong physical deterrent, a clear "stop" point for vehicles, and a system that sits flush with the road surface when lowered.
AGD Systems supplies and installs automatic rising kerbs for commercial and public sector sites across the UK. We help you choose the correct kerb width, height and control method, then deliver a complete installation with commissioning and ongoing support.
A rising kerb is a hydraulically operated road blocker that raises from a recessed housing in the ground to restrict vehicle access. When lowered, the unit sits flush with the road surface to allow normal traffic flow.
Compared with a boom barrier, a rising kerb provides a stronger physical restriction. It is often used where the entrance needs a more robust "vehicle stop" solution or where a barrier arm is not suitable.
Automatic rising kerbs can be specified for a wide range of sites, including:
If your site experiences repeated unauthorised vehicle access, or you need a tougher solution than a parking barrier, a rising kerb can be an effective alternative.
Rising Kerbs and Road Blocks
AGD rising kerb systems are built for durability, using a welded steel frame with a heavy-duty top plate and a hydraulic power pack designed to raise and lower the unit smoothly.
A programmable controller manages operation and can coordinate access control inputs and signalling such as traffic lights. Vehicle detection loops can be used to support safe operation and help prevent the kerb rising when a vehicle is present in the danger area.
Rising kerbs can be specified with an emergency lowering function so the entrance can be made safe in the event of a power cut. During a site survey we will confirm the best fail-safe approach for your location and operational needs, especially for sites that require emergency access at all times.
Rising kerbs are available in a range of widths to suit different entrances, typically from 2.0 metres up to 5.0 metres. Different kerb heights can also be specified depending on the level of restriction required, from lower heights suited to cars and vans through to higher security options intended to deter heavier vehicles.
We will recommend the correct size and height based on the vehicle types using the entrance, the traffic flow, and your security requirements.
Rising kerbs can be integrated with common access control methods to match how your site operates, including:
Where suitable, these can operate alongside safety devices and vehicle detection loops to support controlled entry, auto-exit protocols and reliable daily operation.
Rising kerbs are a specialist product that require correct groundworks, drainage consideration, 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 and safety devices.
If you need a robust vehicle access control solution and want to explore whether a rising kerb is right for your site, speak to AGD Systems. We will survey the entrance, recommend the correct specification, and provide a clear quotation for supply, installation and commissioning.
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.
