A new specification for geotextile grout filled mattresses

April 1st, 2021

By George R. Koerner FIGURE 1 GGFM being filled incrementally. Courtesy of HUESKER Geotextile grout filled mattresses (GGFM), also referred to (in ASTM D18.25/D35.05) as fabric-formed concrete (FFC) or fabric-formed concrete revetments (FFCR), are erosion-resistant concrete linings made from durable, permeable fabric forms that are filled with high-strength grout. GGFMs are generally sloping structures placed […]

Stabilization and reinforcement of wind farm access roads with geosynthetics

October 1st, 2019

This project is the construction of the first commercial-scale wind farm in North Carolina. It was for a renewable power generation facility providing clean energy. Constructing the wind farm required subgrade stabilization and reinforcement for more than 60 miles (97 km) of access roads that needed to be built in order to erect 104 turbines […]

Geosynthetics for reinforcement and stabilization

June 1st, 2019

Geosynthetics are widely used for reinforcement and stabilization, particularly in transportation-related applications, including base stabilization, reinforced soil slopes (RSS) and mechanically stabilized earth (MSE) walls. This issue of Geosynthetics considers many such applications from multiple viewpoints. Sachin Mandavkar and Mehari Weldu look at very tall MSE walls and RSS through several case studies in “Geogrid […]
