A drain that clears and then blocks again has a structural cause — root intrusion, pipe collapse, displaced joints, or incorrect fall. CCTV camera inspection shows exactly what's happening inside, so you fix the right problem the first time.
If your drain has been cleared multiple times and keeps blocking at the same point, you're treating the symptom. These are the structural causes CCTV investigation regularly finds.
Tree roots enter through pipe joints, grow to fill the pipe bore, and catch debris. Clearing removes the roots temporarily — they return unless the entry point is addressed.
Ground movement, settlement, or age cause pipe joints to separate. The offset creates a step that catches solids, builds up, and eventually blocks.
Older clay, concrete, or plastic pipes can crack, flatten, or collapse under load. No amount of clearing fixes a structurally failed pipe.
A drain with insufficient gradient retains water and sediment. Solids accumulate until the pipe blocks. This is a design issue, not a maintenance one.
Wipes, grease, construction debris, or combined build-up at a specific junction point — CCTV identifies exactly where and what.
Excavating to find a blocked drain without knowing where the problem is means opening multiple locations — expensive, disruptive, and often inconclusive if the structural fault isn't found on the first attempt.
CCTV inspection pins the location, depth, and nature of the fault before a single shovel moves. Your contractor goes into the ground knowing exactly where to dig, what they'll find, and what the repair involves.
For councils, body corporates, and commercial property managers, CCTV condition reports also serve as an asset management record — documenting the state of drainage infrastructure at a point in time.
Push-rod and robotic crawler cameras access pipes via existing chambers or rodding points — no excavation required.
Every inspection produces documentation ready for your plumber, engineer, or insurer.
Full-length internal video of the inspected pipe, timestamped and annotated — ready to review, share, or archive.
Structured written report with defect notation — root intrusion, structural damage, joint condition, blockage location, and repair recommendations.
Pipe position and invert levels confirmed at access points. Fault locations referenced to surface features so excavation is precise.

If the drain is blocked and hasn't been cleared, a CCTV camera may not be able to pass the blockage — in which case a plumber should clear the line first. However, if the drain clears and then re-blocks, CCTV investigation is the right next step to find the structural cause. Contact our team and we can advise based on your situation.
Our equipment handles a wide range of pipe diameters and materials including PVC, concrete, clay, cast iron, and HDPE. Suitable pipe sizes range from 75mm up to large culvert systems. Contact our team with your pipe size and access point details to confirm suitability.
Root intrusion is one of the most common causes of recurring blockages. CCTV inspection identifies exactly where roots have entered, the degree of intrusion, and whether the pipe joint or wall has been damaged. This information determines whether root cutting, pipe relining, or excavation and replacement is the right solution — without guessing.
