Industrial vacuum air trucks have a smaller blowers therefore not as fast as hydro excavation. They do dump dry so excavated material can be re-used for backfill which is particularly helpful in cases of environmental remediation. Industrial Air Vacuum is also not capable of digging as deep as hydro-excavation, however, used in the proper setting the "air knife" can knock you a home run.
Industrial Vacuum Excavation - "Air Knife" Case Study
In this video case study, T-Rex Services uses industrial air vacuum services to excavate around sensitive tree roots in Austin, TX. Preserving the structure of the trees at this location was important to the business of the client, for both monetary as well as environmental reasons.
The job started as a hydro-excavation job and even at low pressure settings the tree roots were mildy effected. Because T-Rex Services can provide both hydro excavation and industrial air vacuum services, the client asked that we switch to using "air knife" excavation to be as low impact as possible. Through our ability to provide both hydro and air knife excavation, this job was a win-win!
T-Rex was able to excavate the space for the new sewer line, making the home owners happy and the tree roots were un-injured making the client happy.
