  • Find out when you expect to have your trench ready
  • Book an appointment to install a Lead-In pipe and cabling for when your trench is ready


Dig your trench

  • Contact Dial Before You Dig on 1100 or https://www.1100.com.au/
  • You may dig the trench yourself, but it’s preferable to have a qualified contractor dig it for you
