Civil Engineering & Construction requires testing of soil, concrete and asphalt. Accuracy of information can prevent major disasters and increase return on investment.  Pro Ikon testing equipment enables accuracy. 

Geotechnical engineering is the branch of engineering concerned with the engineering behaviour of earth materials. Geotechnical engineering is important in civil engineering , but is also used by military, mining, petroleum, or any other engineering concerned with construction on or in the ground. Geotechnical engineering uses principles of soil mechanics  and rock mechanics  to investigate subsurface conditions and materials; determine the relevant physical/mechanical and chemical properties of these materials; evaluate stability of natural slopes  and man-made soil deposits; assess risks posed by site conditions; design earthworks  and structure foundations; and monitor site conditions, earthwork and foundation construction.

A typical geotechnical engineering project begins with a review of project needs to define the required material properties. Then follows a site investigation of soil, rock, fault distribution and  properties on and below an area of interest to determine their engineering properties including how they will interact with, on or in a proposed construction. Site investigations are needed to gain an understanding of the area in or on which the engineering will take place. Investigations can include the assessment of the risk to humans, property and the environment from natural hazards such as earthquakes, landslides, sinkholes, soil liquefaction, debris  and rockfalls.

A geotechnical engineer then determines and designs the type of foundations, earthworks, and/or pavement subgrades required for the intended man-made structures to be built. Foundations are designed and constructed for structures of various sizes such as high-rise buildings, bridges, medium to large commercial buildings, and smaller structures where the soil conditions do not allow code-based design.

Foundations built for above-ground structures include shallow and deep foundations. Retaining structures include earth-filled dams  and retaining walls. Earthworks include embankments, tunnels, dikes, levees, channel, reservoirs, deposition of hazardous waste  and sanitary landfills .

Geotechnical engineering is also related to coastal  and ocean engineering. Coastal engineering can involve the design and construction of wharves, marinas, and jetties. Ocean engineering can involve foundation and anchor systems for offshore structures  such as oil platforms.

The fields of geotechnical engineering and engineering geology  are closely related, and have large areas of overlap. However, the field of geotechnical engineering is a specialty of engineering, where the field of engineering geology is a specialty of geology.
