1. Soil Type and Texture Classification
Soil composition refers to the proportion of sand, silt, clay, and organic matter in the land. Common classifications include:
- Sandy soils – fast-draining but low in nutrients
- Clay soils – nutrient-rich but retain water and may expand
- Loamy soils – well-balanced and ideal for construction and agriculture
Understanding the texture helps determine the soil’s strength, stability, and suitability for structural foundations or landscaping.
2. Load-Bearing Capacity and Engineering Suitability
For commercial or industrial development, it’s essential to evaluate the load-bearing strength and geotechnical characteristics of the soil. Factors include:
- Compaction levels and resistance to shifting or settling
- Soil depth and rock layer presence
- Ability to support foundations, basements, or heavy structures
A soil test report from a geotechnical engineer provides detailed analysis critical for site planning and construction safety.
3. Moisture Retention and Drainage Behavior
The soil’s moisture-handling capacity plays a major role in managing water flow and preventing issues like erosion or waterlogging. Consider:
- Permeability – how quickly water passes through the soil
- Water table level and flood potential
- Suitability for stormwater management and septic systems
Good drainage reduces the risk of foundation damage and supports long-term land usability.
