Geosynthetics have been used successfully in stabilizing steep slopes of residual soil and weathered rock. Geotextiles placed horizontally in layers have helped to prevent landslides, which are generally induced by heavy rainfall. The tensile reinforcement and filtration help to stabilize the slopes or embankments. Through slope classification and geotechnical engineering reports, it can be determined what reinforcement type is needed to prevent landslides. [...] 1. Geotextiles
Geotextiles are permeable fabrics used for reinforcement, protection, filtration, drainage and separation, and they are commonly used in conjunction with soil or rock. Geotextiles fall into two categories, woven and non-woven. Woven geotextiles use perpendicular fibers woven to make up a cloth like material. The fibers of non-woven geotextiles are more random and are often made of synthetic polymer.

Geotextiles perform several essential functions that work together to control erosion and enhance slope stability. A single geotextile layer can often fulfill multiple roles, making it an efficient engineering solution.
### Soil Stabilization and Reinforcement
Geotextiles reinforce weak soils by distributing loads and limiting soil movement. This reinforcement improves slope strength and reduces deformation under traffic loads, rainfall, and gravitational forces. [...] The slope surface must be properly graded and cleared of sharp objects, debris, and loose materials. Good surface preparation ensures full contact between the geotextile and the soil.
### Anchoring and Fixing Techniques
Geotextiles are secured using stakes, pins, anchor trenches, or mechanical fasteners. Proper anchoring prevents slippage and maintains position during rainfall and runoff.
### Overlapping and Seaming Requirements [...] Geotextiles play a critical role in protecting slopes from erosion and structural failure in both natural and engineered environments. As construction expands into more challenging terrains, controlling soil movement and maintaining slope stability have become essential for long-term safety and sustainability. Geotextiles provide an effective, adaptable, and proven solution for reinforcing slopes, managing water flow, and preventing surface and subsurface erosion across a wide range of

### Reinforcement
Woven geotextiles and geogrids add tensile strength to the soil mass, distributing applied loads and improving shear resistance. On soft or weak soils where a slope cannot support its own weight, reinforcement is the primary function. High-strength geogrids used in Geosynthetic-Reinforced Soil (GRS) walls and slopes are designed to deliver this tensile capacity with low strain and a high bond coefficient with soil.
### Filtration and Pore Pressure Relief [...] Woven geotextiles are manufactured by interlacing yarns in a grid-like pattern. The result is a fabric with high tensile strength, low elongation, and a relatively tight aperture — properties that make them well-suited for structural reinforcement on steep embankments and retaining wall systems. [...] Geotextile fabric for slope protection is a permeable synthetic or natural material installed on or within a slope to control erosion, reinforce soil, and manage water movement. Depending on the product, it functions as a filter, reinforcement layer, separator, or surface cover — preventing soil loss from rainfall, runoff, and gravity.
