Services
Our expertise covers various main areas including Conduit Condition Evaluation; Water Leakage Detection; Pipe Rehabilitation; Utility Survey; and Slope Leakage Inspection for Buried Water-carrying Services.
Conduit Condition Evaluation: To inspect the underground pipeline and manhole condition by Closed Circuit TeleVision (CCTV) and Man Entry Survey. This method provides an effective and safe way to investigate the condition of pipes with diameter ranging from 80mm to 2100mm.
Water Leakage Detection: To locate the point / line of leak through Leak Noise Correlator (LNC) or Mechanical Listening Device (MLD). This is a non-destructive way to figure out the suspected location of leakage to facilitate subsequent repairing work.
Pipe Rehabilitation: To repair the defected pipeline or section through pipe lining (i.e. part lining / full lining). This is a trenchless method to structural / operational defected pipes without carrying out excavation work, and hence avoid any disturbances to members of the public.
Utility Survey: To locate the alignment and depth of underground utilities (i.e. power cables, water pipes, etc.) through Pipe and Cable Locator (PCL). PCL is an effective tool to assist you to carry out safe excavation by minimizing the chance of damaging the underground utilities.
Slope Inspection: To inspect and monitor all Buried Water Carrying Services (BWCS) affecting slopes in order to ascertain the stability of slope. The techniques of conduit condition evaluation, water leakage detection and utility survey should all be employed in slope inspection works.
