Which type of soil has good load bearing qualities and drains freely?

Coarse grained soils are characterized by larger particle sizes and a granular structure, which contribute to their excellent drainage capabilities and high load-bearing qualities. This type of soil typically includes gravel and sand, allowing water to flow through easily, thus minimizing the risk of waterlogging. The voids between the larger particles also facilitate good air circulation, helping to maintain a stable environment for structural loads.

The physical properties of coarse grained soils mean they can effectively support heavy structures, making them ideal for foundations and load-bearing applications. In geotechnical engineering and construction, the performance of soil in both load-bearing capacity and drainage is crucial, and coarse grained soils often provide the best combination of these qualities.
