ISO/TC 221 develops international standards for geosynthetics, ensuring that these materials are reliable, durable, and safe for use in construction, infrastructure, and environmental applications. These standards help enhance the performance and sustainability of civil engineering projects.

ISO/TC 221 is a technical committee under the International Organization for Standardization (ISO) that focuses on "Geosynthetics". Geosynthetics are synthetic products used in civil engineering and construction applications to improve the performance of soil and enhance the properties of the ground.
