The company's vehicles don't feature the typical 8x4 spec. Its 'standard' chassis, for example, is a full sleeper G cab Scania, with the powerful 12.7-litre engine, delivering 490bhp.
The bodies are full-spec, double-skinned steel Loadmaster models, with front and rear cornerposts, a 5mm Hardox floor, and raked rear end with a hydraulic AutoLift tailgate.
Other tippers in the fleet include two Euro 6 DAF CF vehicles, delivering 510bhp, fitted with insulated alloy bodies with extra-durable 8mm hardened aluminium floors.
Transport manager Brian Clark defends the specification, saying the vehicles are more productive and give better performance on the road.
"Even on short haul trips, they can shave 10 minutes off a journey time," he says, and deliveries are quicker on site. "The driver has no need to get out of his cab at all," adds Clark.
"Put simply, we can be tipped and gone by the time the driver of a conventional tipper is walking back to his cab having just manually released the tailgate locking bar. Because of the extra performance of the vehicles, our productivity is raised."
Over a typical week, he says, the performance improvement could result in three extra trips.
