What is Pipeline Exposure?

Pipeline exposure uses hydrovac to safely uncover existing buried pipelines without risking the protective coatings, cathodic protection systems, or the pipe wall itself. Common in oil and gas, water, sewer, and pressurized utility maintenance, the technique exposes the work area cleanly so welders, inspectors, and engineers can do their jobs without damaging adjacent infrastructure.

Key Benefits in Merrimack

• No risk of mechanical strikes that compromise pipe integrity
• Coating-safe — preserves cathodic protection and FBE/3LPE coatings
• Bell holes can be sized exactly to the work scope
• Allows operator presence while pipe is exposed (mechanical equipment cannot)
• Suitable for emergency pipeline repair when speed and precision both matter
