Specialty underground work in Charlotte requires more than an excavator. Congested utilities, active facilities, finished pavement, limited access, and unknown subsurface conditions can turn a straightforward repair or installation into a high-risk project.
Charlotte Stormwater coordinates hydrovac excavation, pipe sediment cleaning, directional boring, and utility locating for commercial, industrial, municipal, HOA, and development sites. The objective is a practical underground scope with fewer conflicts, less avoidable surface disruption, and clear responsibility from investigation through restoration.
Specialty Underground Capabilities
Hydrovac Excavation
Hydrovac uses controlled water and vacuum to expose buried infrastructure or remove material where conventional digging presents added risk. Typical uses include utility daylighting, pipe and structure access, post-construction cleanup, trench-drain cleaning, and support for point repairs or tie-ins.

Pipe Sediment Cleaning
Accumulated sediment, stone, and debris reduce stormwater capacity and can cause upstream ponding or recurring backups. We evaluate access, material volume, downstream controls, and pipe condition before selecting vacuum cleaning, controlled flushing, or a combined approach.
Cleaning can also prepare a line for camera inspection and expose defects that were hidden by sediment. Removed material is captured and managed according to the project scope rather than intentionally flushed into downstream SCMs or waterways.
Directional Boring
Horizontal directional drilling can install conduit or compatible pressure pipe beneath pavement, drives, landscaped areas, and other features without opening a continuous trench. It is useful when maintaining access and limiting surface restoration are major project constraints.
A boring scope may include bore-path planning, utility conflict review, entry and exit pits, product-pipe installation, tie-ins, and surface restoration. Feasibility depends on soil conditions, bore length and diameter, required cover, existing utilities, access, and the design requirements for the installed line.
Utility Locating and Verification
Underground work should start with a realistic picture of what is already in the ground. We coordinate required public locates, private utility locating when needed, records review, field markings, and targeted hydrovac daylighting to verify critical crossings.
Locating identifies the likely route of buried infrastructure; daylighting physically exposes selected points to confirm position and depth. Using both steps helps the field plan reflect actual conditions before excavation or boring begins.
When a Combined Scope Makes Sense
- A stormwater pipe must be cleaned before its condition can be inspected
- A utility conflict needs to be located and daylighted before repair excavation
- A new line must cross an active drive or parking area with minimal disruption
- A failed pipe or structure requires hydrovac access, repair, backfill, and pavement restoration
- A construction project needs underground cleanup and documentation before turnover
- Multiple specialty contractors would otherwise leave coordination gaps between locating, access, installation, and closeout
How We Plan the Work
- Define the outcome — cleaning, exposure, repair access, crossing, installation, or investigation
- Review site constraints — operations, traffic, access, utilities, drainage, soils, and restoration limits
- Locate and verify — coordinate required locates and daylight high-risk conflicts when appropriate
- Select the method — hydrovac, vacuum cleaning, directional boring, conventional excavation, or a combination
- Execute and document — complete the approved scope, manage removed material, and record key field conditions
- Restore the site — close access points and coordinate paving, concrete, grading, or landscape restoration included in the proposal
Projects We Support

FAQ
What counts as specialty underground work? It includes work that needs a controlled or trenchless method, advanced locating, or coordination across multiple underground disciplines. Common examples are hydrovac excavation, pipe sediment cleaning, directional boring, utility daylighting, and repairs in congested sites.
When is directional boring better than open trenching? Directional boring is often considered when a line must cross pavement, a drive aisle, landscaping, or another area where a continuous trench would create major disruption. Site access, soils, utilities, line type, and engineering requirements determine whether boring is feasible.
Can you find private utilities? Private utility locating can be included or coordinated when site-owned lines are outside the public locate system. Records and electronic locating have limits, so critical conflicts may also need hydrovac daylighting for physical verification.
Can one project include locating, hydrovac, and boring? Yes. Combining those activities under one planned scope is often the safest way to verify crossings before a bore or underground installation. The proposal will identify the included services, responsible parties, and restoration limits.
Do you remove sediment from underground stormwater pipes? Yes. We scope pipe sediment cleaning based on access, pipe size and condition, material volume, downstream controls, and disposal requirements. Cleaning may be paired with inspection or repair when the system has a recurring blockage or known defect.
