<p>We have developed a method for making effective use of unused small-diameter thinned wood as a ground reinforcement material for small buildings. The results of evaluations including materials testing of the reinforcement material, full-scale plate load testing of the reinforced ground, and static axial compressive load testing of the standalone reinforcement material showed that: (1) the reinforcement material had sufficient strength to support the building load, (2) settlement of the reinforced ground was reduced, and the reinforcement material was effective in controlling differential settlement of the building, (3) the reinforcement material was able to secure the allowable ground bearing capacity required for small buildings (30-50 kN/m2). This method reinforces the ground to a depth of 2 m below the foundation (reinforcement material length: 2 m), which is considered to be the most important part of the foundation ground for small buildings, and allows the foundation ground to be designed as composite ground.</p>
