"Cotterill Civils were really helpful all the way through, we had to make a few changes along the way and they were able to assist us in doing so. The road had to be closed and they were able to get the pipe to us on time as requested.”

Ducting general principles

Here’s a quick guide to some general ducting principles*:

  • All runs must be laid as straight as possible
  • If needed, you can carefully bend the ducts or use pre-formed bends supplied
  • There can be no more than one pre-formed 90° bend in any single run of duct
  • Pre-formed 90° bends can’t be installed in any duct linking two joint boxes
  • Footpath or service strip ducting must be laid at 350mm depth of cover
  • All space alongside the duct must be backfilled with granular fill to a minimum thickness of 75mm
  • For all Single Dwelling Units (SDU) duct must be terminated on the external surface of the property
  • The duct termination point shall be in a location that will allow unrestricted access for any future maintenance activity
  • All ducts must be provided with a draw rope after installation, unless it’s agreed locally to substitute the draw rope with a cable
  • Please notify your field based coordinator (FBC) when the duct has been laid and is ready for inspection
