What is Emergency Excavation?

When a utility strike, water main break, or sudden subsidence happens, conventional excavation is too slow and too dangerous. Emergency hydrovac crews mobilize on short notice and expose the impacted infrastructure safely while gas, water, or electrical hazards are still active. Getting eyes on the damage sooner is what keeps an outage from stretching out.
