A slope stability simulation conducted using Rocscience Slide2 version 9.017 software proved that coir geotextiles can effectively reinforce slopes,
Two innovative geotextile-based slope stabilization and erosion control approaches were developed in this study, including vegetation-geotextile composites and geotextiles treated with alkali-activated binder (AAB). Experimental investigations were conducted to evaluate the effectiveness of different slope protection measures in delaying runoff onset, lowering erosion rates, and improving slope stability under varied rainfall intensities and slope gradients. It was found that bare slopes [...] Skip to main contentSkip to article Image 2: Elsevier logo Journals & Books Help Search My account Sign in Access throughyour organization Purchase PDF Search ScienceDirect ## Article preview Abstract Introduction Section snippets References (41) Cited by (4) Image 3: Elsevier ## Geotextiles and Geomembranes Volume 54, Issue 1, February 2026, Pages 36-49 Image 4: Geotextiles and Geomembranes # Regular Paper [...] This study investigated the erosion control performance of vegetation-geotextile composites and alkali-activated geotextile (AAB) systems for slope stabilization under varying rainfall intensities and slope inclinations. Comprehensive experimental assessments were conducted to assess the effectiveness of various slope protection strategies in delaying runoff, reducing erosion rates, and improving slope stability. The main findings are summarized as follows:
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. ### What are the options for slope stabilization? [...] Geotextiles address multiple failure mechanisms at once: reinforcing soil, controlling drainage, protecting exposed surfaces, and separating dissimilar materials. Engineers, contractors, and municipalities across Iowa use them on everything from highway embankments to riverbank revetments. This guide covers the main types of geotextile fabric, how they stabilize slopes, how to choose the right product, installation best practices, and common applications. Key Takeaways: [...] When a slope needs to resist significant tensile forces — where the soil mass itself cannot hold without additional support — woven geotextiles are the right tool. They distribute applied loads laterally and improve shear resistance across the slope profile. One limitation: wovens have lower permeability than nonwovens. They're not used as standalone drainage or filtration layers. Complex slope systems often pair them with nonwoven drainage composites.
