After performing electrical liner integrity and leak location surveys for over 17 years I-CORP's emphasis is now on teaching the technology to others (with TRI/T-CLIC), locating troublesome leaks (as opposed to final CQA surveys), and performing more unusual surveys (above). In addition to conventional applied potential electrical techniques, I-CORP also uses natural potential (for GCLs), acoustic (for batten strips), and infrared spectroscopy (landfill gas monitoring) techniques.

  • Geoelectric Liner Survey Equipment and Expertise in Australia
    After performing geoelectric liner leak location and integrity surveys worldwide since about 1985 and teaching others how to do so since 2004, Dr. Ian D. Peggs, P.E., P.Eng. (I-CORP INTERNATIONAL Inc.) reports that he has sold his survey equipment to Tom Seymour of Terra Firma Laboratories in Melbourne, Australia. The transfer occurred during what was Dr. Peggs’s fifth trip to Oz in 2017. During t... »
  • Avoiding Whales in Anaerobic Digesters
    By Ian D. Peggs, P.E. – In 2014, shortly after being placed in service, one of two geomembrane-lined and covered anaerobic digesters generated extensive whales—“bubbles” in the lining system. Attempts to remove the apparent gas from under the cover were made unsuccessfully until it was realized that the cover was being uplifted by gas under the liner. Within two or three days, there were whales se... »
  • SURVEY: Extra-Wide Geomembranes
    I-CORP International’s Dr. Ian D. Peggs, P.E., P.Eng has shared a survey on extra-wide geomembranes. Your participation is invited. Responses are sought from manufacturers, distributors, installers, construction/contracting firms, design engineers, etc. The information gathering project aims to initially assess the market potential for 11.6m-wide, seamless panels of polyethylene and polyprop... »
  • 10 Geomembrane Questions
    Questioning the practice of engineering has long been part of the geosynthetics field. It is this on-going dialogue and re-evaluation that leads to new manufacturing innovations, better CQA, more economical and more sustainable designs, and much more. Here, we present geomembrane questions, as contributed by Dr. Ian D. Peggs, P.E., P.Eng of I-CORP INTERNATIONAL: We install high-density polyethylen... »
  • Graphene and the Next Generation of Geosynthetics
    By Ian D. Peggs – Geosynthetic materials and products continue their steady development, as additive packages and manufacturing technologies evolve. Today, however, is different. Today, we are truly on the verge of a significant leap in geosynthetic performance. The enabler? Graphene. That single layer of carbon atoms has a specific strength higher than steel. It is self-repairing and has higher e... »
