Soil & Geotechnical Testing

Particle size distribution: This measurement determines the proportion of different size particles present in the soil, including sand, silt, and clay.

Moisture content: This measurement determines the amount of water present in the soil, which affects the soil’s strength and compressibility.

Dry density: This measurement determines the density of the soil when it is dry, which is an indicator of the soil’s compaction and strength.

Atterberg Limits: These measurements determine the consistency of the soil, including its plasticity and shrink-swell properties.

Permeability: This measurement determines the ability of the soil to allow water to pass through it, which affects the soil’s suitability for construction and other uses.

Shear strength: This measurement determines the maximum force that the soil can withstand before it fails in shear, which is important for evaluating slope stability and other factors.

pH: This measurement determines the acidity or alkalinity of the soil, which affects the growth of plants and other organisms.

Cation Exchange Capacity (CEC): This measurement determines the soil’s ability to hold and exchange positively charged ions, such as calcium, magnesium, and potassium.

Total Nitrogen (TN): This measurement determines the amount of nitrogen present in the soil, which is an important nutrient for plants.

Organic Matter (OM): This measurement determines the amount of organic matter present in the soil, which affects the soil’s fertility and structure.

Available Phosphorus (P): This measurement determines the amount of phosphorus available in the soil, which is another important nutrient for plants.

Electrical Conductivity (EC): This measurement determines the ability of the soil to conduct electricity, which is an indicator of the soil’s salinity and fertility.
