Service Overview
Professional Hydroexcavation Services in Indiana
Non-destructive excavation using pressurized water and vacuum technology to safely expose and verify underground utilities without the risk of damage.
What is Hydroexcavating?
Hydroexcavating, also known as hydrovac or vacuum excavation, is a non-destructive excavation method that uses pressurized water to break up soil and a powerful vacuum system to remove the resulting slurry. This technique has become the industry standard for safely exposing underground utilities without the risk of damage associated with mechanical digging.
Unlike traditional excavation methods that use backhoes or shovels, hydroexcavating eliminates the risk of striking and damaging utility lines. The precise control of water pressure allows operators to carefully excavate around utilities while the vacuum system immediately removes the soil, creating clean, accurate excavations.
This method is particularly valuable for utility verification, potholing, and exposing utilities in congested areas where multiple lines may be present. It’s faster than hand digging, safer than mechanical excavation, and provides the precision needed for accurate utility location documentation.
Key Benefits
Non-Destructive
Eliminates risk of damaging utilities compared to mechanical excavation methods.
Precise & Accurate
Allows for exact utility location verification with minimal ground disturbance.
Fast & Efficient
Faster than traditional hand digging while maintaining safety and precision.
Safe Operation
Reduces worker injury risk and eliminates utility strike incidents.
The Hydroexcavating Process
Our systematic approach ensures safe, accurate utility exposure every time
Site Assessment
Our team evaluates the site conditions, soil type, and identifies the target utility location. We review existing utility records and mark the work area.
Equipment Setup
We position our hydroexcavation truck with pressurized water system and vacuum tank. Safety barriers and traffic control are established as needed.
Pressurized Water Excavation
High-pressure water (typically 2,000–4,000 PSI) breaks up soil around the utility. The water stream is precisely controlled to avoid damaging the utility line.
Vacuum Extraction
The loosened soil and water slurry is immediately vacuumed into the onboard tank. This creates a clean, precise excavation without mechanical digging.
Utility Exposure & Verification
Once the utility is exposed, we verify its exact location, depth, and condition. Photos and measurements are documented for records.
Backfill & Site Restoration
After verification, the excavation is backfilled with the extracted material or approved backfill. The site is restored to its original condition.
Common Applications
Utility line verification and depth confirmation
Potholing for design verification
Exposing utilities before construction
Locating utility crossings and conflicts
Verifying as-built utility positions

Frequently Asked Questions
Common questions about hydroexcavation services
What is hydroexcavation?
Hydroexcavation (also called hydrovac or vacuum excavation) is a non-destructive excavation method that uses pressurized water to break up soil and a powerful vacuum system to remove the resulting slurry. This technique safely exposes underground utilities without the risk of damage associated with mechanical digging.
How is hydroexcavation different from traditional excavation?
Unlike traditional excavation with backhoes or shovels, hydroexcavation eliminates the risk of striking and damaging utility lines. The precise water pressure control allows careful excavation around utilities while the vacuum immediately removes soil, creating clean, accurate excavations with minimal ground disturbance.
What is potholing and when is it needed?
Potholing is the process of creating small test holes to visually verify the exact location and depth of underground utilities. It is needed before construction to confirm utility positions, resolve conflicts between utilities, verify as-built locations, and meet ASCE 38 Quality Level A requirements for subsurface utility engineering.
How long does hydroexcavation take?
A typical pothole (2–3 feet diameter, 4–6 feet deep) takes 15–30 minutes to excavate. Project timelines depend on the number of potholes needed, soil conditions, and site accessibility. Most utility verification projects are completed within 1–2 days of fieldwork.
Is hydroexcavation safe for all utility types?
Yes, hydroexcavation is safe for all utility types including gas, electric, water, sewer, and telecommunications. The pressurized water (typically 2,000–4,000 PSI) is powerful enough to break up soil but cannot damage properly installed utilities. This makes it the safest method for exposing utilities in congested areas.
How does hydroexcavation work with utility locating services?
Hydroexcavation is often used as a verification step after utility locating. While GPR and electromagnetic locating identify approximate utility positions, hydroexcavation provides visual confirmation by physically exposing the utility. This combination delivers Quality Level A accuracy per ASCE 38 standards — the highest level of utility location certainty.
What soil conditions affect hydroexcavation?
Hydroexcavation works effectively in most soil types. Sandy and loose soils excavate quickly, while clay and compacted soils require more time and water pressure. Frozen ground may require heated water. Rocky soils with large stones may need alternative excavation methods. Our team assesses soil conditions during site evaluation.
What industries commonly use hydroexcavation services?
Hydroexcavation is widely used in construction, utility installation, road work, telecommunications, oil and gas, industrial facilities, and municipal infrastructure projects. Any project requiring safe utility exposure or excavation near existing infrastructure benefits from hydroexcavation’s non-destructive approach.
