Hydro excavation

Today you get to see some of the work I do,as a drainlayer all my work requires excavating some trenches are deeper than others. This is Jeromy and Keegan using the Hydro excavator to dig a 2m deep hole so I can reapir a drain. Hydro excavation uses a vacum truck and a high pressure water blaster to dig the hole ,this is great here as there are so many under ground cables where we are working.
