This study aims to assess plant fibers' efficacy in reducing soil swelling in expansive conditions. Testing on clay and marl soils included incorporating incremental amounts (1%, 3%, 9%, and 18%) of Alfa, jute, and sisal fibers. Without fibers, significant soil swelling occurred, but their inclusion effectively mitigated the issue. Sisal fibers showed the highest effectiveness at 18%, followed by jute fibers, and then Alfa fibers. Combining different fiber types improved overall stability. Clay soils outperformed marl soils. Findings highlight the cost-effectiveness and eco-friendliness of plant fibers as a solution against soil swelling.
