Professional Underground Utility Locating & Subsurface Investigation in Baltimore

Private Utility Locating

Maryland 811 protects publicly owned utilities, but a significant portion of Baltimore's underground infrastructure is privately owned and entirely outside the scope of 811 markings. Blood Hound specializes in identifying private subsurface assets that put excavation crews at risk, including:

• Private electrical, data, and communication lines
• Water service, sewer laterals, and force mains
• Irrigation, drainage, and stormwater systems
• Underground fuel lines and storage tanks
• Parking lot, campus, and site lighting utilities

Using electromagnetic (EM) locating and ground-penetrating radar, Blood Hound's field crews deliver high-confidence results that give Baltimore project teams the information they need before excavation begins.

Ground-Penetrating Radar (GPR)

Baltimore's older neighborhoods and industrial zones often contain a mix of documented utilities and unknown or abandoned subsurface infrastructure. Blood Hound's GPR scanning services provide nondestructive detection beneath concrete, asphalt, and soil for:

• Non-conductive utilities that electromagnetic methods cannot locate
• Unknown, abandoned, or inadequately documented lines
• Voids, subsurface anomalies, and buried hazards
• Structural elements below paved and hardscaped surfaces

GPR is an essential tool on Baltimore projects where aging infrastructure and incomplete utility records increase subsurface uncertainty.

Vacuum Excavation

Blood Hound offers wet and dry vacuum excavation services as a safe, controlled method of exposing underground utilities without mechanical risk. In Baltimore's dense urban and commercial environments, vacuum excavation minimizes surface disruption while allowing precise utility confirmation. This service is frequently used for:

• Utility potholing and daylighting
• Depth verification and design confirmation
• Emergency utility access and targeted repairs
• High-density job sites where mechanical digging poses unacceptable risk

Concrete Scanning

Before any cutting, coring, or drilling into concrete on a Baltimore project, Blood Hound performs GPR concrete scanning to identify embedded hazards including rebar, post-tension cables, electrical conduits, and plumbing lines. Concrete scanning protects workers, prevents structural damage, and reduces costly project interruptions.

Leak Detection

Baltimore's water and sewer infrastructure includes aging mains that are prone to hidden leaks. Blood Hound uses non-destructive acoustic and correlating leak detection technology to pinpoint leak locations in buried water systems, irrigation networks, and industrial piping — reducing excavation requirements, limiting water loss, and enabling targeted repairs.

CCTV Pipe Inspection

Blood Hound deploys robotic camera systems to inspect stormwater, sanitary, and industrial pipeline infrastructure throughout Baltimore. CCTV pipe inspection identifies blockages, structural defects, root intrusion, infiltration, and other conditions affecting system integrity — all without excavation. Detailed inspection reports support maintenance planning, regulatory compliance, and capital improvement decisions.

Geospatial Services

Blood Hound's geospatial services deliver high-resolution site mapping and documentation using drone-based imaging, LiDAR, and subcentimeter GPS positioning. Deliverables integrate with CAD and GIS platforms to support design coordination, long-term asset management, and accurate project recordkeeping across Baltimore-area projects.

Subsurface Utility Engineering (SUE)

Blood Hound provides SUE services at QL D, QL C, and QL B quality levels for Baltimore engineering and design projects. SUE deliverables reduce subsurface risk, support ASCE 38 compliance, minimize design conflicts, and lower the likelihood of costly utility relocations during construction.

Electromagnetic Locating (EM)

Electromagnetic locating is a core methodology used to identify conductive buried utilities. Blood Hound's technicians apply EM locating throughout Baltimore project sites, often in combination with GPR and vacuum excavation, to produce a complete and accurate picture of subsurface conditions.

CAD and GIS Mapping

Following field investigation, Blood Hound uses cutting-edge technologies to deliver detailed CAD drawings and GIS-compatible files documenting utility locations, depths, and conditions. These deliverables give Baltimore engineers, project managers, and facility owners the accurate subsurface records needed for current projects and future planning.

Uncertain subsurface conditions create real hazards — for your crew, your budget, and your project timeline. Blood Hound gives Baltimore-area project teams the accurate subsurface intelligence they need to excavate safely and plan effectively.
