Definition

Geotechnical engineering is the branch of civil engineering

concerned with the engineering behavior of earth materials , includes investigating existing subsurface conditions and materials;

assessing risks posed by site conditions;

designing earthworks and structure

foundations; and monitoring site conditions, earthwork and foundation

construction.

Foundation1. Deep Foundation

Deep foundations are used for structures or heavy loads when shallow foundations can not provide adequate capacity, due to size and structural limitationsType – Pile– Bored Pile– Caissons– Piers.

Bina Nusantara

Foundation2. Shallow Foundation

Shallow foundations are used for simple structures Type – Footing– Slab Foundations– Raft Foundations
