Soil Classification

Soil is classified into one of three major groups:

• Coarse-grained soils (e.g. sands and gravels)
• Fine-grained soils (e.g. silts and clays);
  
• Highly organic soils (referred to as "peat")

Different classes of soil have different engineering properties. For example, sandy soils will absorb water rapidly compared to a clay soil. Almost all soils are a mixture of these three classes. Soils vary considerably based on the rock they have weathered from, their age, chemical makeup, the topography and even the surrounding vegetation.

Comprehensive soil classification systems are designed to allow a transition from field observations to basic predictions of soil engineering properties and behaviors. Broadcrest provide soil drilling and logging to classify soil properties, including:

• Particle size, color and description
• Moisture content
  
• AS1547 Classification

Borehole samples are sent to a NATA accredited soils laboratory to be classified and tested in accordance with Australian and international standards. To learn more about the tests Broadcrest offers click here.
