What Is SBC of Soil?

Hard soils: These soils are generally rocky in nature, incompressible, and can withstand reasonably good loads. Solid rock, moo rum, and rocky soils are examples. Soft Soils: These are alluvial soils and are compressible when loaded. They can carry a lot of loads. Common clay and common soils are examples of this. Spreading soils: These soils are compressible when confined and prevented from spreading. These soils, when loaded, spread laterally. Sand and gravel are examples of this type of soil. Read more
