What type of fabric is designed to prevent movement of backfill materials?

Geotextiles are specifically engineered fabrics used in a variety of civil engineering applications, including the installation and retrofitting of underground storage tanks (USTs). Their primary function is to manage soil movement and filter water while providing a barrier to the migration of backfill materials. By utilizing geotextiles, engineers can prevent the mixing of different soil types and maintain the integrity of backfill, which is crucial for the stability and durability of the UST installation. These fabrics are designed with woven or non-woven structures that enhance their ability to support various loads while allowing for drainage, making them ideal for applications where soil stability and separation are essential.
