Recently, the utilization of nanomaterials has been gaining popularity in soil improvement procedures. The aim of this study is to investigate the feasibility of using nano-MgO (NM) along with fibers (FBRs) to improve clay soil’s load-bearing capacity and settlement by using both conventional and model experiments. First, the optimum water content values for NM–clay mixtures were determined by compaction tests. For mixtures prepared with the optimum water content, the addition of 1.5% NM alone resulted in a 1.33-times improvement in bearing capacity, and the addition of 1.5% 90 mm FBRs alone led to a 1.83-times improvement. Utilizing 1.0% NM and 1.5% FBRs at 90 mm long resulted in a 3.07-times improvement in bearing capacity. The temperature of the mixing water was found not to be a significant parameter, and curing duration impacted the results only for NM addition. Significant settlement improvements were achieved by adding the two materials together. Therefore, utilizing NM and FBRs together resulted in an optimal outcome for clay soil.
