Experts in Cutting Back Ingress into Pipework Blocking Flow

Trimming Back Intruding Connections - Following the pre-handover CCTV survey, our client had been requested to remove x6 protrusions from various diameter pipework around the site. The site could not be signed off until these were removed. Due to the depth and location of the protrusions, excavating would have been an extremely complex solution.

Remote no-dig removal of drain protrusions to restore lateral flow

Lateral Cutting – We worked with our client to clean the pipework prior to removing the protrusions. We attended with our Prokasro 4.0 unit and a variety of attachments to cater to the differing pipe sizes around the site. The protrusions were both plastic and clay, which required different cutting heads to avoid damaging the incoming pipework.
