Dry Injection Binding System (DIBS): A First-of-Its-Kind Waterless Stabilization Technique for Desert Sands Using Encapsulated Lime and Recycled Plastic Mesh Fibers

The Dry Injection Binding System (DIBS) presents a novel, water-independent approach for stabilizing desert sands through the dry injection of encapsulated lime and recycled plastic mesh fibers. This system addresses the limitations of conventional methods that rely on moisture-dependent chemical reactions or surface treatments, which are unsuitable for arid regions. In DIBS, encapsulated lime is pressure-activated during compaction, enabling chemical bonding without external water input, while mesh-structured plastic fibers provide internal reinforcement to improve cohesion and shear strength. This dual-action stabilization is designed for dry, loose sands where traditional lime, cement, or polymer methods often fail due to poor moisture availability and dispersion challenges [5][9][14][20][34]. The integration of dry injection, encapsulated activation, and recycled mesh reinforcement has not been previously combined in this form, making DIBS a unique contribution to geotechnical engineering, with potential applications in desert infrastructure, erosion control, and sustainable soil improvement.
