Atarfil Presentation on ‘White Geomembranes Performance’
By Ryan Mcnamara Area Manager North America, Atarfil, Suffolk, VA and Borja Nanton Civil Engineer, Atarfil, Granada, Granada, Spain
HDPE Geomembranes have been used in containment applications for the past 50 years. Over this period, Polyethylene Geomembrane formulations have changed markedly with a design need to contain higher-risk contaminants stored in more challenging environments. One of the significant product developments has seen the emergence of “White Top Layer” Geomembranes. Atarfil would concur, and our most recent immersion and exposure data are compelling. It is not simply the thermal behaviour that is beneficial; the additive types required to meet the challenges of stabilizing white layers also serve significantly better protection when subjected to UV and Immersion Testing. This translates to substantially longer predictions of Geomembrane performance life.

COMANCO & Watershed Geo Prevent Groundwater Contamination by Installing A Geosynthetic System
COMANCO advances installing a geosynthetic system to prevent groundwater contamination in Florida. The team has now completely installed the 50 mil super Gripnet, followed by synthetic turf and a ballast system of sand infill over the turf. The ClosureTurf® system used in this project is a new method of capping containment sites. Using Watershed Geo ClosureTurf® instead of classic sod eliminates the need for excess soil and constant maintenance.
