The Vacmaster 1000 uses (soft digging) compressed air funneled through a specialized nozzle at the tip of the air lance which makes the soil explode (so to speak) and allows the powerful vacuum system to quickly and efficiently remove the loose soils. Compressed air is non - disruptive; causing no damage to the existing road base, compressed air will not even damage a utility line if and when we come in contact with one. By using air, we are also able to backfill the hole with the same cuttings that were removed during the clearing process, thus saving money on backfill material and drums. The dry air Soft Dig® method eliminates the use of water as a cutting tool, since water cannot be compressed and is a conductor; you have effectively made it safer to do the work and saved money at the same time. The Soft Dig® method takes the guess work out of unknown, sometimes difficult to find underground utilities that are not covered by the One Call System or untraceable by private locating companies. Having the ability of a 100% view of the subsurface within the top 5 ~ 8 feet gives everyone involved a safe feeling that we will all go home at the end of the day just as they arrived safe and sound.
