What's the problem?

Do you need to locate, inspect, or repair your underground infrastructure? Detect subsurface features and receive superior reporting before building.

From marking to mapping, we find what's underground. Locate utilities, voids, and anomalies with superior ground penetrating equipment. Pinpoint the exact horizontal positioning of subsurface features within:

  • Asphalt
  • Concrete
  • Soil
  • Pavement

Confirm and target problems through video pipe inspection. Receive condition reports of your sewer and sanitary system with utility visuals. Maintain detailed maps to streamline your facility's building timeline.

  • Inspect cross bores with lateral launch
  • Detect inflow and infiltration
  • Conduct 360 degree manhole imaging
  • Navigate <6" pipes with push camera

Vacuum excavation is the only approved method to exposure buried utilities. Vac work is superior to heavy machinery digging as it avoids accidental utility strikes. Vacuum excavation utilizes either air or water pressure to break up the soil. The vacuum device collects the spoils to accomplish:

  • Trenching
  • Test holing
  • Remote digging
  • Line boring

Optimize drain line flow and complete isolated repairs on damaged sections. Maintain sewage lines for maximum capacity and eliminate buildup. Revitalize storm and sanitary pipe by restoring line integrity. Perform repairs on:

  • Cracks
  • Infiltration
  • Corrosion
  • Root Intrusion
