Relining a Tailings Dam Stormwater Channel with Limited Access

By Concrete Canvas – In August 2016, a Concrete Canvas® Geosynthetic Cementitious Composite Mat (GCCM) was used to line a drainage channel at Glenridding Mine, Ullswater, Cumbria. The objective was to re-line an existing 200m long channel on top of a tailings dam to prevent damage from runoff during severe rain storms. In recent years there have been a number of extreme rain storms in the La... »

Improving Drainage at Expansion Joints in Rigid Pavements

By GSE Environmental – Repairing damaged expansion joints in rigid pavements is a costly endeavor. Not only is the cost of the repairs high, but repair projects can go on for miles and shut down vital lanes of traffic important to commuters and local commerce. The primary cause of premature damage is insufficient drainage under rigid pavements. MANAGING EXPANSION JOINTS Expansion joints are partic... »

PODCAST: Pullout Anchor Testing in Erosion and Sediment Control

Jay Sprague of the South Carolina-based Denver Down Research Facility took on a private client’s pullout anchor testing questions with erosion and sediment control systems and components. The results began to yield revealing data on anchor pullout performance, and in a way that has not been previously explored. Listen to “Pullout Anchor Testing in Erosion and Sediment Control” on Sprea... »

MSE Wall Failures vis-à-vis the Lack of Geotechnical Filters

By Dr. Robert M. Koerner – Since 2001, the Geosynthetic Institute has accumulated data on failures of geosynthetic-reinforced mechanically stabilized earth (MSE) retaining walls. Our MSE wall failures database presently has 301 cases, of which 191 (63%) have been caused in whole or part by water within, or adjacent to, the reinforced soil zone. We sincerely hope that our past writings and webinars... »

PODCAST: Leap Frog Ideas for Low Impact Development

How do we create a more water-centric infrastructure? That’s a question LimnoTech senior engineer Dr. Daniel Medina, P.E., D.WRE addresses in his work. Low impact development strategies are very important to his work. It’s trickier than just saying “use LID,” though. Inequalities between cities and countries make is harder for some infrastructure strategies to get adopted. Priorities are different... »
