In civil engineering, geogrids are widely used in various fields, including but not limited to road construction, railway engineering, water conservancy engineering, environmental engineering, foundation treatment, and slope protection. By laying it on the surface or inside of the soil that needs to be reinforced, geogrids can effectively disperse and transmit loads, limit lateral displacement and settlement of the soil, and thereby enhance the overall stability and durability of the soil.

PP geogrid, also known as polypropylene geogrid, is a geosynthetic material made from polypropylene material through special processes. Thanks to its excellent physical properties and wide range of applications, PP geogrids play a crucial role in the field of civil engineering. This article will provide a detailed introduction to the characteristics, classification, application, and importance of PP geogrids in engineering.
