Condition Assessment Breakthrough for AC Pipes

Speaker: Csaba Ékes, Ph.D., P.Geo., President, SewerVUE Technology Corp.

 

Pipe Penetrating Radar (PPR) is the underground in-pipe application of Ground Penetrating Radar (GPR), a non-destructive testing method that can detect defects and cavities within and outside non-ferrous (reinforced concrete, vitrified clay, PVC, HDPE, etc.) pipes. The key advantage of PPR is the unique ability to map pipe wall thickness and deterioration including voids outside the pipe, thus enabling accurate predictability of needed rehabilitation or the timing of replacement. With recent developments the technology is able to accurately image pipe wall deterioration and other defects previously unobtainable in asbestos cement (AC) pipes. This presentation covers recent advancements of PPR inspection technology and discusses elected case studies in detail.
