ABSTRACT:
This invention contemplates method and apparatus for laying rodent-protected cable from a moving vehicle, using unprotected cable to which sheathed cementitious material is applied prior to subterrain burial. The sheathing serves only to retain shape of fresh, unset cementitious material around the cable in the course of handling and transport within and from the vehicle structure, to the buried position of the cable. The sheathing being degradable (in the course of time) and no longer needed once the sheathed cementitious material has set, after burial.
