Geosynthetics for Precipitate Clogging

April 1st, 2023

Q: We are retrofitting a highway edge drain where rubberized concrete was used as the base course layer. What type of geotextile or geosynthetic should we consider for this project’s drain?  A: Clogging of geotextiles, geonets, geopipe and/or geocomposites is a challenging design for certain soil types or unusual situations. This is one of them. […]

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 […]

Geosynthetics opportunities and solutions in shale gas extraction

October 1st, 2018

While natural gas contained within shale rock is geologic and thus ancient by its very nature, the practice of its removal by horizontal drilling coupled with hydrofracking is a relatively recent development (Figure 1). Indeed, these dual technologies are making possible the recovery of huge amounts of natural gas—so much so that one can envision […]

Geocomposite lamination strength ASTM test method: Time for an update

August 1st, 2018

Recent project experience that included continuous peel testing across the roll width of geocomposite materials has shed light on the issue of peel strength between geotextiles and geonets that are heat-bonded together. The variability of peel strength across a roll width is found to be much greater than expected, with the typical standard deviation often […]

History of geosynthetics use on national forest roads

June 1st, 2017

Introduction The objectives of this article are to document the long history of geosynthetic materials used in the U.S. Department of Agriculture (USDA) Forest Service and other rural roads, to document the many creative and useful ways geosynthetics have been used, and to promote the cost-effective uses of geosynthetics in road projects today, particularly on […]
