In Memoriam: André Rollin, a Geosynthetics Pioneer

By Chris Kelsey – The geosynthetics field has lost one of its earliest adopters and consistent champions, engineer André Rollin, M.Sc.A., Ph.D., FEIC, FCSME (1941 – 2017). André passed away on August 13 at the Vaudreuil-Soulanges Palliative Care Home after a lengthy battle with illness. André’s long and active career was characterized by a constant interest in growth—of the geosynthetics field, of... »

Gas barrier performance and EVOH layers in geomembranes

EVOH Layers and Better Gas Barrier Performance for Geomembranes

Geosynthetic barriers perform exceptionally well in liquid containment applications, but gas barrier performance can still be improved. Volatile organic compounds, for example, can diffuse through barrier systems. The rate is low, but the incorporation of an EVOH layer in a geomembrane has shown that the diffusion rate of VOCs can actually be much lower. Applications that utilize geosynthetics and... »

Drainage and Venting of Geosynthetic Containment Systems

PODCAST: Proper Drainage and Venting of Geosynthetic Barrier Systems

The field of geosynthetics has seen a strong increase geomembrane performance debate. The topics have looked roundly at performance in exposed environments, in buried service conditions (e.g., landfill lining), from installation perspectives, and much more. The Berlin 2 think-tank gathering in 2014 on HDPE geomembranes, Queen’s University’s barrier studies, and the Geosynthetic Institute’s ever-gr... »

Protecting a Caribbean Shoreline and Coal-Fired Power Plant

TenCate Geosynthetics has published a new video that features how TenCate Geotube® technology was used to repair and protect a Caribbean shoreline. The immediate area included a large utility company, which had seen the shoreline erode significantly over a period of years. Storm surges with waves exceeding 3m had been a major factor in the waterfront deterioration, which had taken 50m of beach. Th... »
