To construct an underground cable line in-situ, cut and immediately evacuate a void in the existing covering surface. Next, lay or apply cable(s) into the void. Then, flow a non-shrinking composition into a portion of the void around the cable to fill a portion of the void. Upon rigidification the cable is encased in the void by the non-shrinking composition. Last, apply a topping material to the exposed surface of the composition in such volume as to fill any remaining portion of the void. |
