PVC conduit has long been considered the lightest in weight compared to steel conduit materials, and usually lower in cost than other forms of conduit. In North American electrical practice, it is available in three different wall thicknesses, with the thin-wall variety only suitable for embedded use in concrete, and heavier grades suitable for direct burial and exposed work. When using reinforced concrete pipe, in addition to the conduit, you get the majority of the structure necessary to support whatever type of load will be generated on top of the conduit. Unlike flexible pipe, where up to 95% of the structure must be painstakingly designed and installed in the field, up to 85% of the design strength of the installation is provided by the concrete pipe.
