Soil Profiles, Residual Soils & Expansive Clays | Complete Geotechnical Guide

Soil Profiles: What They Are, How They Form, and Why They Matter in Geotechnical Engineering

A soil profile is the layered structure created by weathering near the surface. Residual soils form in place, while erosion of topsoil causes sedimentation problems and aquatic dead zones. This complete guide explains the processes, clay formation, and engineering importance.

Sedimentary Soils vs Residual Soils | Geotechnical Engineering Guide

Sedimentary Soils: How Residual Soils Are Moved, Redeposited and Transformed

Sedimentary soils are residual soils that have been eroded, transported and redeposited. Their properties depend on the source rock and the transporting agent. This guide explains the differences, the dangers of random fill, and the importance of engineered fill.

Positive pore water pressure reduces inter-particle friction. Capillary suction in unsaturated soil increases friction and strength.

Unsaturated Soils, Capillary Suction and Expansive Clays: Why Soil Strength Changes with Water

Unsaturated soils gain strength from capillary water suction. When they become saturated they can lose that strength, collapse, or generate huge swelling pressures. This guide explains the simple physics behind these important geotechnical behaviours.
