Soil reinforcement is a method used to enhance the strength and performance of soil by integrating materials that improve its engineering properties. The concept of reinforcing soil with natural fibers is an age-old practice. In recent times, the use of randomly distributed fiber-reinforced soils has gained significant attention within the field of geotechnical engineering due to its effectiveness and sustainability.
Types of Soil Reinforcement Materials:
Several materials can be utilized to reinforce soil, including:
Woven Geotextiles: Fabric-like materials that allow water to pass while holding soil particles in place, offering both filtration and reinforcement.
Polymer Geogrids: Manufactured from polyethylene or polypropylene, these grids are either uniaxial or biaxial, providing high tensile strength in one or both directions.

Polyester and Fiberglass Geogrids: Often knitted or stitched, these materials are coated with substances like polyethylene, PVC, or bitumen to enhance durability.

Steel Strips: The traditional material used in “Reinforced Earth TM” structures, offering exceptional tensile reinforcement.
Welded Wire Mesh: Commonly applied in mechanically stabilized earth (MSE) walls and similar structures.
