Abstract: The invention relates to a method of manufacturing a reinforced oblong concrete product for longitudinal load-bearing purposes, in particular a driving pile. According to the present invention reinforcing fibers are used to prevent break-up of the concrete due to radial forces which occur during driving, and the concrete composition is provided with said reinforcing fibers before the concrete composition is applied to the reinforcing wire. This method reduces the amount of heavy labour and cost. The invention also relates to a driving pile comprising reinforcing fibers.
