The findings from your CCTV Drain Survey can clearly outline specific repairs needed to resolve any problems found within the drainage system. The video evidence from the survey highlights each problem within the pipework in great detail allowing for an accurate quote for the required repairs.
Hairline Cracks in Clay Pipe
Fine hairline cracks within clay or concrete pipes can usually be repaired without the need for excavation. Patch lining is the preferred method of repair where a short resin sleeve is inflated inside the pipe and then left to cure over the crack, sealing it.
Root Intrusion in the Pipe
Tree roots enter pipes through even the smallest of joint gaps, potentially causing future blockages. When identified during a drain survey, roots can be cut using a rotary cutter, followed by the installation of a resin liner within the affected section of pipe. The liner will also prevent future root penetration into the pipe.
Full Pipe Collapse
A full pipe collapse will need the ground to be opened up and the collapsed section of the pipe to be dug out and removed and replaced with new pipe. Again a CCTV Drain Survey Nottingham can be used to locate the exact point where the collapse has occurred to limit the amount of excavation needed.

Displaced or Open Joints
Groundwater ingress is typically the result of an older property’s pipes settling and its joints pulling apart slightly allowing wastewater to escape. Localised patching with a patch liner is generally the preferred method to effect such repairs.
Pipe Sag or Belly
A low point in a pipe which can cause a ‘sag’ or ‘belly’ can collect water. The correct course of action for a sag or belly is to re-grade that section of pipe and set it to the correct fall. Whilst Jetting may clear a blockage caused by a low point, the problem will return.
CCTV drain surveys in Nottingham can highlight any problems with your drains and recommend the correct course of action to repair them. For further information on who is responsible for repairing your drains please visit drainage responsibilities for Nottingham properties.
