A method of prestressing simultaneously a quantity of concrete units comprising the steps of end-to-end disposition a plurality of concrete units one of which carries a cable receiving opening; interposed between adjacent units separadorescada one of which has a corresponding cable reception opening; aligning the cable receiving openings of the units and the separators to form an elongated concrete structure provided with a cavity that extends continuously therethrough; running a tension cable through said cavity so that its ends protrude from it; tightening said cable by applying a tensile force that reacts against the elongated structure of concrete; introducing pressurized slurry into said cavity so that the cable is stuck in place in the cavity; and then after hardening or setting the grout the wires at the points where they pass through said spacers.
