As part of the UK’s long‑term Smart Motorway initiative—an effort launched by the Highways Agency to replace aging steel barriers with safer, longer‑lasting concrete solutions—Extrudakerb (Maltby Engineering) Limited developed the innovative Extrudakerb Concrete Barrier (ECB). Since its introduction in 2018, the ECB system has become a widely deployed barrier type across major improvement schemes, offering superior durability, reduced maintenance, and improved roadway safety.
Producing and installing concrete highway barriers is a complex, highly time‑sensitive operation. Concrete is mixed at a plant, transported to site, then immediately placed through a slipform paver. During transit, however, concrete naturally loses slump and can dry out—requiring on‑site tempering before placement.
These adjustments depend on an operator’s judgment and require carefully adding small amounts of water. But because these corrections weren't monitored or recorded, crews had no accurate way to verify the amount of added water. This manually driven process caused inconsistencies, slowed paving, and introduced avoidable delays
Before we put Verifi on our trucks, we were typically paving 10-12 loads per shift. With the addition of Verifi as part of the overall paving process, we typically pave 16-20 loads per shift. Overall the innovative partnership has allowed Extrudakerb to push traditional boundaries, excelling against project timescales.Materials and Concrete Technology Manager - Extrudakerb
