Pile Capacity
Vertical downwards loads (Compression): Pile carrying capacity for vertical downward loads, comes from two things: The frictional resistance over their side…
Deep Foundations (Pile Foundations)
Deep foundations, also called as pile foundations, are used when there is not sufficiently strong soil at a reasonable depth, and…
Shallow foundations
Design: Shallow foundations are used where the soil has enough bearing capacity and shear strength (in other words strong enough) at…
