Soil testing is a critical component of any excavation service, as it provides crucial information about the composition and stability of the soil at a given site. At the fundamental level, soil testing involves the collection of soil samples from the excavation site, which are then subjected to a battery of physical, chemical, and geotechnical examinations.

More advanced soil testing techniques are often employed to gain a deeper understanding of the soil’s structural integrity and drainage characteristics. Civil Scope Earthworks is a reputed Demolition Sydney company, known for doing all pre-excavation procedures including soil testing.

Soil Type B — This type of soil is relatively less stable as compared to type A. However, soil type B isn’t as sticky as the type A variety. This type of soil comes with a strength of .5 to 1.5 tons/sq. There are several examples: silt loam, silt, angular gravel, etc.

Soil Type CType C soil comes with a strength of .5 tons/sq foot. Only gravel and sand are found in this type of soil. Since it’s an unstable type of soil, it doesn’t provide firmness. Any type of soil that has water leakage is considered type C.
