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). Debris from the cut trench is evacuated (e.g., vacuumed) from the trench as the trench is cut. The trench may be backfilled using a flowable composition. In one example, the flowable composition rigidifies after being flowed into the trench, and thereafter is substantially impermeable (e.g., having a hydraulic permeability of less than 0.0000001 cm/s upon drying), non-compressible and/or non-expanding.

Trenching methods and apparatus

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.

Laying and protecting cable into existing covering surfaces

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.
