How is soil type important for excavation and construction?
Soil type plays a major role in excavation and construction projects because it affects stability, drainage, and the type of foundation required. Different soils such as sand, clay, loam, or rocky ground behave differently when excavated and when supporting structures.
For example, clay soils may hold water and expand, while sandy soils typically drain better but may require additional compaction for stability. Understanding soil conditions helps ensure proper grading, drainage, foundation support, and septic system performance.
