Solmax launches online Geosynthetic Drainage Tool for design engineers

October 16th, 2020

Geosynthetics play a vital role in the containment of solid and liquid waste in landfills, mining, energy, construction, and oil and gas applications. To help design engineers accurately specify the materials needed, Solmax has launched an online resource for engineers–its Geosynthetic Drainage Tool. Geosynthetics are used to contain, drain and protect, but specifications will be […]

Distinctive uses of geosynthetics

October 1st, 2020

This issue of Geosynthetics takes a look at bridges, drainage/coal combustion residuals and highways/geosynthetic wall systems. It’s a diverse issue showing the breadth of geosynthetics applications. Patricia Guerra-Escobar’s “Reinforced embankments for the causeway for a North Wales bridge project” examines the use of geogrids in the replacement of a 160-year-old bridge in the U.K. “CCR […]

Enhanced moisture management of pavement systems through capillary suction

June 1st, 2020

By René B. Laprade and John M. Lostumbo Moisture within pavement layers is a principal cause of pavement deterioration (Cedergren 1994, Christopher and McGuffey 1997, Henry and Holtz 2001). Specific problems associated with moisture include (1) reduction in pavement strength caused by excess water in the base course layers and/or the subgrade soils, (2) shrinking […]

Geosynthetics: An extraordinary handler of water

April 1st, 2020

Most geosynthetics deal with water in some shape or form. Geosynthetics are an extraordinary handler of water, whether the project involves erosion control, water storage, wastewater, stormwater, seawater or mining. This issue of Geosynthetics looks at water applications in several forms. Drainage, leak detection layers, potable water storage, a mechanically stabilized earth (MSE) wall at […]

MSE wall failures can be mitigated through the use of geotextile filters

April 1st, 2019

For the past 17 years, the Geosynthetic Institute (GSI) has been accumulating data on failures of geosynthetic reinforced mechanically stabilized earth (MSE) retaining walls. We presently have 320 cases, of which 201 (63%) have been caused in whole or part by water within, or adjacent to, the reinforced soil zone. We sincerely hope that our […]

The magic of water and geosynthetics

February 1st, 2019

Water is a fundamental issue in many projects using geosynthetics. From erosion control to reservoir liners and covers, from landfill leachate pond barriers to coal ash dewatering, handling water and the effects of water are considerations nearly every engineer employing geosynthetics considers. Geosynthetics can effectively manage water applications of erosion control, reinforcement, barriers, filtration and […]
