## How to determine the Water Content of Soil? (7 Methods)

The moisture content or water content of soil mass is a quantitative measure of the wetness of a soil sample. Mathematically, water content for a given soil mass is defined as the ratio of the weight of water to the weight of soil.   Water Content, w = Weight of water / Weight of Soil […]

## Soil Liquefaction

Soil Liquefaction occurs when a saturated or partially saturated soil loses its strength and stiffness under cyclic loadings such as an earthquake or sudden change in stress condition. In this phenomenon, the soil material which is solid in general behaves like a liquid. This phenomenon is most usually encountered in saturated, loose sandy soils because

## Types of Foundation

Foundation is one of the most important elements of a structure, the purpose of which is to transfer load from structure to the ground by acting as a connection between both. Based on the use, soil condition, load from the structure Foundation can be classified and hence used accordingly. Before commencing any construction project, the

## What is Soil-Cement?

Soil-cement is a mixture of soil and measured amount of cement, and water compacted at high density. They all together form a hardened mixture like concrete, under the hydration action of cement. It is generally used as a low-cost pavement base for airports, parking areas, residential streets, roads, shoulders, and materials-handling and storage areas. It

## Geotechnical Investigations

Geotechnical investigations are necessary to obtain information about the physical properties of soil earthworks and foundations for proposed structures. Geological Investigations should be conducted for new projects and reviewed for existing structures to determine the general geologic setting of the area at and near the project. This is also done to determine the geologic conditions

## Machine Foundation

Machine foundation is designed so that the dynamic forces of the machine are safely transmitted to the soil through the foundation. The machine foundation should be designed to limit the amplitude displacement and not disturb the people who work near the machine. When the design of machine foundations does not satisfy the acceptable value of
