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.

Geotechnical Investigation
Bina Nusantara
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
