Vacuum Excavation
Vacuum excavation is one of the safest and most precise ways to expose buried utilities or remove soil in sensitive areas. At Safe Site Utility Services, we use both air-vac and hydrovac methods to loosen soil and extract it using a high-powered vacuum system. This approach protects underground infrastructure, prevents costly damage, and gives crews the visibility they need to work confidently around utilities.
VACUUM EXCAVATION SERVICES
UTILITY TEST HOLE POTHOLING, HYDROVAC EXCAVATION AND TANK DEBRIS REMOVAL
Instead of relying on mechanical digging, our equipment uses pressurized air or water to break up the ground. Soil is then vacuumed into a debris tank, leaving a clean, controlled excavation. Because the digging process is non-destructive, it’s ideal for areas where traditional machinery may be unsafe or too invasive.
Vacuum excavation works especially well in congested utility corridors, residential neighborhoods, landscaped areas, and any location where even a small mistake could cause service outages, repairs, or safety hazards.
This method provides industry-standard precision for:
- Utility test holes (potholing)
- Exposing utilities during construction
- Controlled trenching or pole-hole excavation
By preventing damage and improving accuracy, our process boosts safety and reduces downtime.
What we do
At Safe Site Utility Services, we specialize in advanced vacuum excavation, hydrovac excavation, and air excavation solutions.
Our equipment and experienced crews handle the entire process from surface cutting to debris removal, delivering precise and clean results.
Our vacuum excavation services include:
Utility potholing
What is Utility Potholing?
Potholing (also called “daylighting” or utility test holes) lets us verify the exact location, depth, size, material, and condition of underground utilities. We document every test hole with data and photos, then survey the exposed utilities. We feed these details directly into your design plans so engineers can avoid or relocate utilities before construction even begins.
SLOT TRENCHING
What is Slot Trenching?
We use hydrovac excavation to dig very precise, narrow trenches in tight or congested areas. Whether you need to expose long runs of existing utilities or perform perimeter “clear” trenches (forming an X-shape), we do it to your exact specifications. That way, you can inspect, repair, or replace utilities with minimal risk.
POLE CLEARING HOLES
What are Pole Clearing Holes?
When you plan to install sign posts, utility poles, bollards, or similar structures, we dig a “clearing hole” first using hydrovac. We create two intersecting slot trenches in an X pattern to confirm that no utilities cross your planned excavation area. After we “clear” the spot, your crew can safely auger or dig without surprises.
Hydrovac Excavation
We rely on high-pressure water and powerful vacuum suction to excavate efficiently — even in hard or rocky soils, clay, caliche, or cobble-laden ground. Our vacuum units generate very high negative pressure, quickly removing the loosened material. These systems can reach depths over 20 feet and access remote or challenging areas using extended hose reach. While this wet excavation process doesn’t let you reuse the spoils immediately as backfill, the gain in productivity outweighs that cost.
Air Vacuum Excavation
In loose or sandy soils, or when working up to about 8 feet deep, we use compressed air to break up soil and a vacuum to extract it. This method causes minimal disruption to the site, and the dry excavated material can often be reused as backfill (if permitted). We also favor this technique in areas where historic or cultural artifacts might be present, so crews can examine the soil carefully before reuse.
