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. This fact allows them to transfer forces to a larger area of soil than would otherwise be the case. Geogrids are commonly made of polymer materials, such as polyester, polyvinyl alcohol, polyethylene or polypropylene. They may be woven or knitted from yarns, heat-welded from strips of material, or produced by punching a regular pattern of holes in sheets of material, then stretched into a grid.

What Is a Geomembrane and How Are They Used?A geomembrane may sound like a medical experiment gone wrong, but its uses and applications are both varied and fascinating. Geomembranes are synthetic membrane liners or barriers used to control fluid migration in a manmade project, structure, or system.

The project to extend the continuous ash disposal facility (ADF) at Eskom’s Majuba power station has passed its midway point. The project will ensure that waste residue from the boiler furnaces is responsibly stored. The project’s contractor, Concor, reported being over halfway with extending the continuous ash disposal facility, located near Amersfoort in Mpumalanga. This project will ensure that the coal-fired power plant can continue generating electricity while complying with ever-stricter environmental regulations regarding the responsible storage of waste.

The three-dimensional geotextile is a new type of geosynthetic material, which is composed of a three-dimensional geotextile core with needle-punched perforated non-woven geotextile attached to both sides. The core of the three-dimensional geometric mesh consists of a thicker vertical rib and slante
