Edge line marking, also known as profiled edge lines or ribbed road markings, is a critical safety feature installed on motorways and dual carriageways throughout the UK.
These specialised road markings serve a dual purpose: providing highly visible edge of carriageway markings while creating an audible and tactile warning system for drivers.
To meet the growing demands for durability, sustainability, and long-term compliance, we have developed EcoRib™ and EcoRib+™ – two bespoke engineered systems designed to extend service life and significantly reduce the carbon footprint of this critical asset.
EcoRib™ is specifically engineered for applications where existing ribbed edge lines have deteriorated beyond viable overmarking. This comprehensive two-machine process removes old markings and installs a complete new profiled system.
Applications:
System Composition:
EcoRib™ combines a durable Methyl Methacrylate (MMA) resin rib structure with HyperLine™ ULTRA acrylic overspray. This two-stage process creates both the tactile profile and a smooth, highly reflective surface layer that optimises water run-off and maximises visibility.
EcoRib+™ is a premium edge line marking system best suited for new surfacing projects or locations where no previous edge line marking has been installed. This single-application system delivers exceptional durability and performance.
Applications:
System Composition:
EcoRib+™ utilises a single-stage application of two-component MMA viscous resin with integrated high-index glass bead technology. The precision-controlled process creates the ribbed profile and retro-reflective surface in one efficient installation.
Both systems are BS1436 certified (P5, R3, RR2, RW2, S2, Q2) and fully compliant with TSRGD Diagrams 1012.2 and 1012.3. Installation uses computer-controlled equipment, ensuring precise rib spacing and height for consistent quality.
For the full spec, check our EcoRib™ and EcoRib+™ technical sheets.
Our EcoRib™ profiled markings system has a typical life expectancy of 5 years with a 36-month performance guarantee, while EcoRib™+ offers 7 years typical life expectancy with a 60-month performance guarantee. Both exceed thermoplastic alternatives in durability.
EcoRib™ is designed for replacing existing worn ribbed markings using a two-stage process. EcoRib™+ is a premium single-stage system for new installations, offering longer service life and extended performance guarantee periods.
Yes, both systems are fully compliant with Traffic Signs Regulations and General Directions (TSRGD) Diagrams 1012.2 and 1012.3, and certified to BS1436 performance standards.
When performance begins to decline, markings can be oversprayed with HyperLine™ ULTRA to restore retro-reflectivity without ever having to remove the rib structure, reducing waste and environmental impact.
Cold-applied MMA systems revolutionise operative safety. They eliminate burn risks to staff and the public by removing the need for heated materials, while the low-pressure application eliminates the risk of injection injury. This commitment to zero-hazard installation is combined with superior durability and environmental performance.
