Vacuum excavation - also known as Hydro Excavation or Sucker Trucks - are now fast becoming the prefered method for safe excavation works, especially when there are services hidden underground. They are quite often used to safely dig around cables and pipes to expose the existing services and sighting their exact location. This then eliminates damage which may have ordinarily have occurred by using other machinery to dig. Vacuum excavation trucks use an extremely high pressure hose to cut into the ground causing the earth to fall apart while the 100mm pipe sucks up the material matter at the same time. It can clean around the services giving a clear line of sight for bigger machinery to then come in and do their work without touching the services found. It reduces any disruptions to the services worked on and saves costly time and repair from services being damaged by bigger machinery.
