WebType B soils include both cohesive and non-cohesive soils. They include silts, sandy loams, medium clays, and unstable rock. Soils that might be classified as A, but have fissures, or are subject to vibration, may also be classified as "B" soils. Type C soils are the most unstable (and therefore most dangerous) of the four soil types. WebFeb 19, 2024 · Type B. Type B soil does not stick together as much as Type A soil. Its compressive strength is between 0.5 and 1.5 tons per square foot. Type C. Type C soil is very unstable because its particles don’t stick together and it has a low compressive strength equal or less than 0.5 tons per square foot.
