Businesses in the concrete truck mixer category transport freshly batched concrete to building and construction sites in vehicles fitted with a rotating drum. The drum keeps the mix moving during the journey to help prevent it from setting or separating before it is placed. Some operators supply concrete as well as delivering it, preparing mixes to suit the required strength, consistency and intended use. Customers can typically arrange deliveries for foundations, floors, driveways, walls and other concrete work, with the mix discharged from the truck through a chute. Delivery access, vehicle size, load quantity and the distance from the truck to the pour can affect what equipment or arrangements are suitable. Some suppliers also offer smaller loads or specialist mixes, while other businesses focus on transport for concrete produced elsewhere. These services are generally used by builders, contractors and householders carrying out construction or renovation work.
