Pneumatic & Hydro-Vacuum Excavation
We provide state-of-the-art technology to solve a multitude of complex excavation problems.
Excavation work requires “safe digging” practices. Our technology redefines safety expectations when performing critical and sensitive excavation work. Unlike conventional methods, this process allows us to safely deal with known and unknown subsurface infrastructures.
Pneumatic- & Hydro-Vacuum Excavation technology uses pressurized compressed air (pneumatic) and/or water (hydro) agitation to loosen and remove soils. Debris and materials are collected using vacuum equipment, maintaining a nearly dust-free operation.
Pneumatic (Dry) Vacuum Excavation
Thompson offers a safe and effective ‘dry’ vacuum excavation process using a custom-designed air system to dislodge and facilitate the matrix to free-flow via the vacuuming process.
Hydro Vacuum Excavation
The hydro-excavation method utilizes relatively low flow, high pressure water to accomplish the dislodging and size the matrix to facilitate simultaneous vacuuming operations. Although this process is faster than dry excavation in terms of cubic-yards-removed production rate, other site factors may warrant the dry, pneumatic method.

- Optimizes precision perimeters of the excavated area
- Minimizes shoring and disposal handing problems due to excess free water or muddy conditions
- Ideal when hydro-excavation concerns are present (slippery or slick surfaces; soil erosion/soil instability/under-mining concerns, housekeeping issues, freezing or icing conditions, conductivity hazards, etc.)
- Vacuum-collected excavation materials (i.e., soils/debris) are drier and may be readily used for immediate backfilling or stockpiling for other uses.
- Identify subsurface utilities and infrastructures frequently missed by pre-surveying detection equipment
- Eliminate the risk of disastrous subsurface utility damage
- Exceptionally high CFM and 28 inch vacuum with custom equipment
- Excavation of “no-dig” areas
- Damage-free utility locating
- Manhole exposing vacuuming
- Uncovering water-line breaks
- Safely creating trenches and duct banks
- Vacuuming of remote material and debris
