Push-rod and crawler camera inspection, connectivity mapping and condition reporting for pipes up to 2 m in diameter.
Push-rod and crawler camera inspection, connectivity mapping and condition reporting for pipes up to 2 metres in diameter.
Drainage condition assessment for councils and asset owners, delivered as interactive field reports.
Maps how the network actually connects, not just where the pits are.
CCTV drainage inspection puts a camera inside the pipe so the condition, the connections and the faults are seen rather than guessed. Push-rod cameras handle house drains, downpipes and small-diameter lines; tracked crawler units with pan-and-tilt heads and lasers inspect stormwater and sewer mains up to 2 metres in diameter. The camera head carries a sonde, so the locator above ground can trace the line, mark it and give a depth at every point of interest.
Connectivity mapping is where the inspection pays for itself. Council stormwater networks and old industrial sites rarely match the drawings; pits connect to lines no one recorded, illegal connections run into the wrong system and abandoned pipes carry water that should not be there. We survey each pit and invert, trace each line, and deliver a network map that shows how the drainage actually connects.
Condition reports follow the WSA 05 conduit inspection reporting code, with each defect classified and scored so an asset owner can rank pipes for relining, replacement or no action. Councils use the reports for asset management programs; developers and contractors use them for dilapidation records before works and clearance inspections after.

Drainage investigation often leads to a civil or hydraulic design: a new connection, a relined main or a stormwater upgrade for a development. The LCG group provides the survey and engineering through LCG Solutions and the residential design through LCG Architects.
From 50 mm house drains with a push-rod camera up to 2 m diameter stormwater culverts and sewer mains with a tracked crawler. Larger box culverts are walked and inspected by a confined-space crew where safe.
Yes. The camera carries a sonde that the locator follows from the surface, so the line is marked and depths recorded along its length, including the point where it leaves the property or enters a council pit. The result is drafted into a connectivity plan.
Defects are coded and scored to the WSA 05 Conduit Inspection Reporting Code of Australia, which is what NSW councils and Sydney Water specify. Reports include the video, still images of each defect and a scored summary per pipe length.
Yes. Recording the condition of council and neighbouring drainage before piling, excavation or heavy vehicle use protects the contractor from claims, and a matching post-works inspection closes the record.
Yes, and it usually is. The same crew locates the other services on site, so the stormwater and sewer lines are shown with the power, gas, water and communications on one AS 5488-2022 plan.
Detection, tracing and marking of underground services using electromagnetic and ground-penetrating radar, to the accuracy each site demands.
Engineering-grade utility survey and drafting to AS 5488-2022, delivering 12D/DWG models, BIM-ready 3D strings and GDA2020 deliverables.
Safe vacuum potholing to positively identify services and achieve the highest Quality Level (QL-A), without damaging the asset.
GPR concrete imaging before cutting, coring or drilling. Locates rebar, post-tension cables, conduits and voids. Radiation-free, no site shutdown.
USTs, concrete substructures, voids and rock seams, plus unmarked-grave, forensic and archaeological investigations.
