Slot trenching is the process of digging narrow trenches for installing pipes, cables or other in-ground utilities. Hydro excavation provides a non-destructive and efficient slot trenching method even on frozen surfaces. It eliminates the potential for serious and costly damage often caused by traditional slot trenchers. Hydro excavation makes it easy and safe to install sprinkler systems, locate underground utilities, and perform similar installations without the risk of damaging previously installed systems or lines.
Hydro excavation is a safer alternative to conventional slot trenching methods. It is ideal for digging trenches through easements and right-of-ways without damaging existing underground utilities.
For slot trenching, Super Products’ Mud Dog Hydro Excavator uses a unique combination of water pressure and vacuum, combined in one self-contained mobile unit. Water is pressurized and injected into the ground through a handheld wand to safely wash soil from the underground area. The resulting slurry is vacuumed from the excavation through a large debris hose connected to a debris tank.
By digging the trench to specifications, the costs for backfill, concrete encasement and asphalt patching are minimized.
