Specialist Highways, Bridges & Infrastructure Maintenance

Outstanding Services to Highway Civil Engineers

RAB have the expertise to design and install long-term, cost-effective solutions for your specialist requirements.

Located in central England, we operate all over the UK and work for main contractors, local authorities and direct with the Highways Agency. We innovate our own products and services, and we have a wealth of product and installation experience to draw upon.

Our Core Services

RAB Associates UK pioneered the development of the Permatrack range of products with Permanite (and subsequently IKO) over the past 15 years. With RAB’s decades of product design experience and Permanite’s (IKO) manufacturing activities we have created one of the most versatile jointing and highway repair systems available on the market today. Please visit our Permatrack  Hub for more information on what Permatrack can do for you.

Whatever the structure, whatever the requirement, RAB can design and install the correct solution to ensure you achieve the best whole life costings possible. We install and repair bridge expansion joints; asphaltic plugs, mechanical, elasomeric, top ups and carry out emergency repairs – we have a cost effective solution for you.

Most ironworks are bedded on brick or concrete biscuits and, over time, the compressive stresses placed on the frames break up the concrete or brick. This leads to the frame shifting or sinking and fast becomes a problem for both road safety and local noise pollution. Simply re-bedding the frames in tarmac or other asphalt products is only a short term fix. RAB install the only system that comes with a 10 year guarantee – the Permatrack Ironworks System. Find out more here.

Improve the whole life costing of your concrete & highway repairs. Don’t accept solutions that need replacing within months or the next year. Our specialist repair solutions give you the best whole life costing and a cast iron guarantee you won’t be going back to that repair anytime soon. We can overband cracks, re-bed ironworks, replace nosings in expansion joints across a variety of structures from port yards to highway bridges.
