  2. Geofoam - Wikipedia

    en.wikipedia.org/wiki/Geofoam

    Geofoam was used to create highway side slope stabilization to prevent any similar issues. The use of geofoam versus conventional restoration resulted in an 84% reduction to the total cost of the project. [4] The largest geofoam project in the United States took place from 1997 to 2001 on Interstate 15 in Salt Lake City, Utah. [5]

    In addition, for most applications of geofoam and geocells, separation is the major function. Reinforcement is the synergistic improvement of a total system's strength created by the introduction of a geotextile, geogrid or geocell (all of which are good in tension) into a soil (that is good in compression, but poor in tension) or other ...

    Geogrids are used to prevent sliding on long and steep slopes during installation and use of a landfill capping system. [1] A geogrid is geosynthetic material used to reinforce soils and similar materials. Soils pull apart under tension. Compared to soil, geogrids are strong in tension.

    Geosynthetics are a type of plastic polymer products used in geotechnical engineering that improve engineering performance while reducing costs. This includes geotextiles, geogrids, geomembranes, geocells, and geocomposites. The synthetic nature of the products make them suitable for use in the ground where high levels of durability are required.

    He used different styles of woven monofilament fabrics, all characterized by a relatively high percentage open area (varying from 6 to 30%). He discussed the need for both adequate permeability and soil retention, along with adequate fabric strength and proper elongation and tone setting for geotextile use in filtration situations.
