When your surveyor hands you your CCTV drain survey report, it can look like a load of old rubbish. Here we give you the meaning behind the main terms and help you with your pipes and with your next decision.
Fractures and Cracks
A fracture to a drain pipe is typically indicated by a crack in the wall of the pipe. These are commonly found in older Clay pipes and do not always need to be repaired straight away, although it is recommended that the drain is monitored for any future problems. The term “multiple fractures” would suggest that the pipe is under stress and is likely to fail at some point in the future, therefore it would be wise to obtain a quote for a repair before any further damage is caused.
Pipe Collapse or Deformation
Pipe Collapse or Deformation – When Sewage Could Start to Back Up: Typically drainage repairs can be completed at a time to suit you. However on occasions when your drainage pipes collapse or have deformed then drainage repairs can not wait as there is a real risk of sewage backing up into your property.
Displaced Joints
When pipe joints have moved due to ground settlement, etc. the amount of shift is normally recorded in the report. This enables the operator to establish whether a simple joint repair is sufficient or whether a full reline is required to cover the affected area.
Root Ingress
Root Ingress and how to classify it in Drainage Surveys, a blocked drain can have root ingress entering through the fine hairline cracks in the underground drain pipes, in time the roots will continue to grow until a blockage occurs, sometimes it can be cleared and sealed and other times it can indicate a larger problem with the underground drain pipe joint or even the surrounding pipe wall.
How Damage Is Graded
Most drainage survey reports grade the detected damage. Most drainage industry survey coding standards for CCTV drain surveys assign each type of fault with a code and assign a condition grade to it. Most condition grades signify a degree of urgency or requirement for action.
