Peter Finlay – Geosynthetic Dewatering Technologies Environmental Remediation – June 2020

During this one hour webinar John Scheirs from ExcelPlas, will discuss the periodic table of geomembranes is based loosely the periodic table of elements. It is a tabular display of the geomembrane types, which are arranged by chemical family, degree of

Peter Finlay will discuss the use of Geosynthetic Dewatering Technologies Environmental Remediation in this webinar.

Section 1. Overview of Geosynthetic Dewatering Technology

  • Its development and applications

Section 2. Outline of components and their importance to the geosynthetic dewatering system

  • Dredging and Pumping
  • Treatment – flocculants and coagulants
  • Geosynthetic container – the fabric, seams etc

Section 3, Why Geosynthetic Dewatering Technologies is a relevant option for Environmental remediation  works

  • Relating this to the Kopeopeo project

  • Conclusion

About the Speaker

Peter Finlay – Geofabrics

While starting out in the Horticulture field and completing a Batchelor of Horticultural Science in 1982,  I then diverged in to civil engineering in the late 1980s to be involved with developing the composite drainage market followed then with the introduction of nonwoven needle punched geotextile into New Zealand.

Joining Maccaferri NZ over 25 years ago I have had a range of roles involved with marketing of mesh products and the growing geosynthetic market.  My horticultural experience has leant me towards a large involvement in erosion, sediment applications and environmental engineering. My current role in Geofabrics (Formerly Maccaferri) has a focus on the containment market which encompasses products and solutions used in the waste and water sectors – geomembrane, geosynthetic clay liners, drainage composites, protection geotextiles and Geotube Dewatering technology.

In the past 25 years I have seen massive growth in the use of Geosynthetics in NZ and internationally and with my environmental focus I see continuing development of these and new technologies to provide solutions to environmental problems such as the containment and remediation of contaminated materials.
