Laying and protecting cable into existing covering surfaces
Methods and apparatus for cutting a trench (e.g., for a fiber optic cable or wire conductors) in an existing covering surface (e.g., a road surface), wherein the trench has a depth of approximately 10 to 12 inches and a width of approximately 0.5 to 1.25 inches. Debris from the cut trench is evacuated (e.g., vacuumed) from the trench as the trench is cut. The trench may be backfilled by flowing a non-shrinking composition into at least a portion of the trench and, after hardening of the non-shrinking composition, applying a topping material to a remaining portion of the trench. In one example, the non-shrinking composition is configured to rigidify within one hour of being flowed into the trench, be substantially impermeable thereafter (e.g., having a hydraulic permeability of less than 0.0000001 cm/s upon drying), and be non-compressible and non-expanding.
