Understanding the causes of failure is fundamental to determining the measures that are taken to prevent a reoccurrence. WRc's Network Operations team provides services to investigate all types of failures. These include failures of metallic, cementitious and plastics pressure pipes, gravity sewer collapses and lining failures. The investigation of a pipe failure will help determine whether the failure is localised or whether it is likely to affect other parts of the pipe. WRc can investigate failures in pressure pipes, gravity sewers, chambers and street ironwork. Our specialists also investigate sewer and surface water flooding incidents. After investigation we can recommend solutions to prevent recurrence. and where necessary our experts can provide expert evidence in court.
