"Air Knife" Vacuum excavation

Some times hydro excavation is not the best way to go.  Many competitors do either air excavation or hydro excavation exclusively.  At T-Rex we are proud of our capability of doing both.  In addition to our 12 Gap Vax hydro excavation trucks we also have a Vacmaster 4000 for when you need that special touch.  The air truck has a much smaller blower so it's not quite as fast as hydro excavation and does not dig as deep.  That said, it does dump dry so excavated material can be re-used for backfill which is particlarly helpful in cases of environmental remediation. Used in the proper setting the "air knife" can knock you a home run.
