Vacuum Excavation
Vacuum Excavation is a quick, non-destructive and economical way to safely locate and expose buried utilities. High pressure air is used to break up the soil, which in turn is vacuumed up into a tank. This method allows for very precise excavations without the risk of damaging buried utility lines, pipes or tree roots.
Typical applications for vacuum excavation include:
• |
Verification of the type, condition, diameter and depth of buried utilities – especially useful for identifying and resolving potential conflicts prior to construction in the design phase. |
• |
Eliminates the need for hand-digging, saving time and labor, and particularly useful for those utilities buried deep or in congested areas. |
• |
Safe methods for excavations, including: |
|
• |
Potholing |
• |
Sign and post installations |
• |
Slot trenches |
• |
Exposing root systems |
• |
Digging under existing structures |
• |
Caisson and foundation excavations |

Vacuum Excavation Procedures
All PULS, Inc. vacuum excavation services are performed by highly trained field technicians.
Vacuum excavation services consist of the following steps:
• |
Tarps are laid around the excavation and surface structures are carefully removed. |
|
• |
Sod is cut and set aside for restoration |
• |
Asphalt and concrete are precisely cut to aid restoration |
|
• |
Rock and soil are broken apart by air jets and the loosened material is vacuumed into a holding tank. PULS, Inc. only uses pressured air to break apart the soil, we do not use water jets. This eliminates the risk of damage that high pressure can cause and allows PULS, Inc. to place all soils back into the excavation. |
• |
Utility lines are exposed, identified and recorded according to client specifications. |
• |
Soil is returned and compacted in the excavated area. |
• |
Surface structures are restored. |
