Type B soils are typically described as which material?

• A. Clay
• B. Sand
• C. Silt or loam
• D. Gravel

Answer: (C)

In excavation safety and soil classification, soils are grouped by shear strength into three types. Type B soils have moderate strength and are often described as silt or loam. Silt and loam are fine-grained and cohesive enough to provide some stability, but they aren’t as strong or uniform as solid clay (Type A) and aren’t as loose or non-cohesive as sand or gravel (Type C). That’s why silt or loam commonly falls under Type B.
