The utilization of repurposed whole textiles to modify the mechanical and hydrogeological soil properties investigates the impact of adding repurposed textiles to lightweight engineered soil, documenting changes in unit weight, water content, and hydraulic conductivity. This study builds upon prior findings, which demonstrated significant alterations in hydrogeological properties when incorporating textile fabric (3% by weight at an aspect ratio of 1:1). Functioning as reinforcement, these fibers enhance the soil's strength, stability, and structural integrity—especially advantageous in erosion-prone areas, regions susceptible to landslides, or locations requiring heightened load-bearing capacity. The outcomes of this parametric study lead to green roof farms playing a pivotal role in extending the advantages of suburban living to urban environments, offering energy efficiency benefits by reducing the need for excessive heating and cooling in commercial buildings. This may offer crucial insights, potentially opening avenues for practical implementation in strengthening highway pavements. However, integrating green roof infrastructure, growing media, and vegetation poses a challenge due to the limited load capacity of buildings. To address this, a promising approach involves incorporating repurposed textiles into lightweight engineered soil, ensuring that the additional components maintain a minimal weight. This innovative technique aims to modify the hydraulic properties of the soil without compromising structural integrity.
