News and Articles

Geotextile encased columns (GECs) were developed to provide efficient foundations for embankments on weak subsoils. These columns, characterized by geotextile sleeves filled with noncohesive material, transmit loads through weak subsoil to suitable bearing strata via the columns. HUESKER‘s video on this geosynthetic solution provides graphics, project images, and technical details to teach u... »

News and Articles

One of the most common needs in infrastructure is proper drainage and filtration engineering. These solutions consolidate soils to accelerate construction windows. They channel liquids into proper retention or detention areas. They guard against soil less and protect waterways. Drainage and filtration engineering impacts landfills, roads, stormwater systems, dams, levees, and many other infrastruc... »

Coastal Engineering Opportunities at GeoAmericas 2016

On by Geosynthetica
News and Articles

Geosynthetic materials are used extensively in coastal engineering and protection projects. The modern geotextiles industry, in fact, emerged in the 1950s in response to flooding in the Netherlands and tropical storm damage in the United States. Since then, a large industry and innovative designs have come along. Geosynthetic tubes and containers provide dewatering and solids separation for large-... »

In March 2014, I published “A Brief History of Geotextiles” in Land and Water Magazine. (A copy of that article may be downloaded in PDF here.) It would take a considerably long manuscript to fully detail the research, projects, events and people who have brought forth geotextiles, let alone the larger field of geosynthetics; but a welcomed result of that small article was post-publication communi... »
