COMPANY PROFILE

I-CORP INTERNATIONAL (I-CORP) was formed in March 1991 by Dr. Ian D. Peggs when he realized the geosynthetic industry's need for a completely independent organization that could provide world-class geosynthetic materials performance information, specialist construction quality assurance (CQA) services and new technology development services; and, at the same time, not be afraid to instruct those with less experience on how to provide the same services. Prior to forming I-CORP, Dr. Peggs was a Vice President of GeoServices, Inc. and President of the international geosynthetics testing laboratory, GeoSyntec, Inc. (both now GeoSyntec Consultants).

I-CORP provides geosynthetic materials engineering/science/durability and field construction/performance expertise. I-CORP staff are polymer/materials/engineering experts. I-CORP is not an engineering design company, but having worked alongside designers, I-CORP staff are well aware of the latest design practices and are well-prepared to collaborate with, and complement, designers at all levels of expertise. I-CORP staff have been, or are, active in North American (NAGS, ASTM, IFAI) and international (IGS, ISO, CEN, IAGI) geosynthetics associations and standards groups in order to stay abreast of the latest developments in geosynthetics technology. They maintain communication with private consultants, manufacturers, and users of geosynthetics around the world. In fact, 40% of I-CORP's business is outside the US. Dr. Peggs' contributions to the geosynthetics industry have been recognized by one of six IGS Awards presented at the 1994 IGS Conference in Singapore for work performed between 1990 and 1994.

Only one other Award was presented to a private consultant, the remainder to university teams. He was also nominated for an IGS Award for the period 1995 - 1998 for his paper "HDPE Geosynthetics - Premature Failures and Their Prediction".

The comprehensive nature and uniqueness of I-CORP's services are shown by a client list that includes resin manufacturers, geosynthetic manufacturers and installers, engineering design companies, operators of government facilities, international corporations, owners of landfills, industry institutes, research institutes, inventors, attorneys and insurance companies in 40 countries around the world

It is I-CORP's intent to respond immediately to your request. And we demand no less from the laboratories (and other organizations) we contract to work on your behalf. We are prepared to mobilize anywhere (nationally or internationally) at anytime. About 40% of I-CORP's work is outside the US. Failures must be analyzed before material evidence is lost or damaged. Leaks must be located and repaired before ground water is contaminated or to prevent a facility being shutdown.

Our objective is simply to get the work done for you, as quickly and as professionally as possible.

Experience

Dr. Peggs has been involved with the failure analysis, research and development, and testing of polymeric materials in bulk, composite, and coating form since 1977. He has had extensive experience with all geosynthetics since 1981 and has specific interest in the nondestructive examination, microstructure, and performance of geomembrane seams. He initiated the use of the multifrequency ultrasonic shadow technique for nondestructive seam inspection and has developed microtome techniques for the microstructural examination of seams. He has been involved with the preparation and management of construction quality assurance programs for geomembrane-lined impoundments and landfills in the U.S., Canada, Europe, South Africa and SE Asia. Dr. Peggs has also been involved in failure analyses for many clients throughout North and South America, Europe and Australia on high-strength geotextile seams, geotextiles, geomembranes, geomembrane seams, plastic pipe, and fiberglass components. He is presently developing infrared thermography technology as the first technique for the nondestructive measurement of geomembrane seam bond strength.

He has performed survivability and durability studies on geomembranes and geotextiles and is Past-Convener of the International Organization for Standardization (ISO) TC38/SC 21 Working Group on the Durability of Geotextiles. He is also past-chairman of the RILEM (TC-144-GMP) Technical Committee on Geomembranes.

He has presented more than 200 papers, seminars, and workshops on geosynthetics for manufacturers, installers, and users of geosynthetics.

Dr. Peggs became involved with the investigation, development, and testing of non-metallic materials, including polymers, during the time that he headed Atomic Energy of Canada's Thermophysical Properties Lab in its Materials Development Branch beginning in 1967.

In 1981, Dr. Peggs became involved with geosynthetics when he initiated and managed the Polymer Engineering Division of Hanson Materials Engineering (now Canspec), a large materials consulting company in Alberta, Canada. His work there in failure analysis, consulting, specifications development, research and development, and quality assurance for geosynthetic lining systems, plastic pipe, and other polymeric materials led to a joint venture between Hanson Materials Engineering and EBA Engineering. Dr. Peggs then became director of the joint venture, GeoSyntech Ltd., which provided specialized geosynthetics consulting and testing services to clients throughout Canada and the United States.

In 1986, Dr. Peggs joined with Joseph E. Fluet, Jr. and J.P. Giroud of GeoServices, Inc. Consulting Engineers (now GeoSyntec Consultants) to establish GeoSyntec, Inc., a geosynthetics testing laboratory in Boynton Beach, Florida. This laboratory became one of the foremost, and most comprehensive, geosynthetics testing laboratories in the world, with clients throughout North America and in 13 countries around the world.

In 1991, Dr. Peggs formed his own geosynthetic materials performance consulting company, I-CORP INTERNATIONAL, which performs state-of-the-art international geosynthetics technology development, and teaches others how to perform state-of-practice projects in over 25 countries. The Industry Insight newsletter, with subscribers in 32 countries, was initiated in 1994. The newsletter was superceded by the www.geosynthetica.net technical resource web site sponsored by the geosynthetics industry. The site has about 400,000 visitors each year.

Typical projects that Dr. Peggs has managed include failure analyses of geomembrane liners, geosynthetic clay liners, and plastic pipes; stress cracking and microstructure investigations of geomembrane seams; curing and microstructure investigations of fiberglass laminates; aging and degradation studies of polypropylene geotextiles; leak surveys on geomembranes under soil and waste cover; interface friction and surface texture/profile studies; failures in HDPE sheet liners on concrete walls; developing a manufacturing and fabrication QC program for PP geomembranes; and investigation of rapid crack propagation in HDPE geomembranes and more recently PP liners and floating covers. These projects have been conducted on liners in ponds, vaults, and landfills; covers; seams; and filters, for a variety of clients that include many utilities, international corporations, engineering consulting firms, hazardous waste firms, geomembrane manufacturers and installers, oil companies, metals companies, marine surveyors, contractors, municipalities, insurance companies, and lawyers.

In 1996 Dr. Peggs applied for patents on a geocomposite membrane GCL. United States Patent 5,788,413 for Geocomposite Membrane was awarded in 1998 – others followed. Dr. Peggs also organized the First US/Germany Geomembrane Workshop in Berlin.
