The GeoU 2020 engineering short courses event has added another world-class instructor to its line up: Markus Wilke. He joins Joel Sprague, P.E., in the "Geosynthetics in Stormwater Controls and Hydraulic Engineering" course (April 8 - 9). GeoU 2020 will be held April 7 - 10 in Austin, Texas and include five high-level short courses, four of which are concurrent. Each...

Geosynthetics are used frequently to support roads that are built specifically for temporary or limited exposure to very heavy loads. This petrochemical installation project, first presented at GeoAmericas 2016 under the title "Non-Conventional Design Road for Heavy Traffic Load in Soft Soils", provides a strong example of how geotechnical challenges are answered by matching project-specific design needs with geosynthetic...

During the GAP 2019 transportation engineering conference, W. Jeremy Robinson, P.E. of the US Army Engineer Research and Development Center (ERDC) presented on work he and his ERDC colleague Dr. John Rushing, P.E. have been involved in. Here, we publish their paper on pavement preservation techniques from GAP 2019 and how to implement these practices in a pavement management...

Welcome to a new Geosynthetica series on manufacturing and innovation! We begin with the first of a few looks at how geosynthetic companies are engineering greener products. HUESKER’s EcoLine is the subject of this first installment. SEARCHING FOR PERFORMANCE IN SUSTAINABILITY It’s been said that the field of geosynthetics was created by manufacturers. There’s a lot of truth in that. Manufacturers...

In mid-2019, Clockspring|NRI acquired Milliken Infrastructure Solutions (MIS). Both companies had large portfolios with infrastructure repair-related technologies, such as pipe wrap and sleeves, epoxies, and geosynthetic cementitious composite mats (GCCM). Now, with the integration process having well advanced, the company has announced a new corporate identity: GeoTree Solutions. GEOTREE SOLUTIONS GeoTree is a legacy geopolymer brand name. MIS acquired the company...

This article has been UPDATED (12 March 2020) to reflect the event’s new dates. For 15+ years, engineers have come to Austin, Texas to attend geosynthetics CQA training courses hosted by TRI Environmental. This year, some are wondering where this well-respected course will be, as a traditional CQA Week has not been announced. This is because a new event is taking...

For 15+ years, engineers have come to Austin, Texas in April to attend geosynthetics CQA training courses hosted by TRI Environmental. This year, some are wondering where this well-respected course will be, as a traditional CQA Week has not been announced. This is because a new event is taking place in Austin--one that offers the same two-day geosynthetics CQA training...

In the latest addition to our GeoAmericas series of stories, we look back at the GeoAmericas 2016 project story of how Groupe Alphard utilized electrical leak location (ELL) surveys and a customized quality control (QC) program to improve a gold mine closure project near the Arctic Circle in the Northwest Territory of Canada. The QC approach and leak location...

In the latest addition to our continuing series of articles developed out of the GAP 2019 transportation engineering conference proceedings, we follow Eli Cuelho, a senior engineer with TRI Environmental. Cuelho has contributed significantly to the transportation field, through his roadway and railway-related research for DOTs and with his accelerated pavement testing and cyclic plate load testing laboratory. Here,...

Composite reinforcement systems that combine geosynthetics with different facing systems and supports (steel mesh, soil anchors, etc.) have grown substantially in use. These systems enable very efficient construction of slopes, walls, and embankments, including at significant angles. Where older infrastructure has suffered, it has become more common to see these newer reinforcement designs utilized for reconstruction. NAUE’s Steel P system,...
