California Bearing Ratio test or CBR is used to calculate the strength of the material for pavement design. CBR test is the test that was developed by the California state highway department of the USA for the determination of subgrade strength of highway and air-filled pavement. It is a penetration test. In this test, a … Read more
In this type of footing, at least two columns are supported in a row and a common foundation is provided. A combined footing is provided when the bearing capacity of the soil is low and required more surface area. Basically, It is made of reinforced cement concrete (R.C.C). Combined footing distributes the load from the superstructure to … Read more
Black Cotton Soil is inorganic clay. It is called black cotton soil due to its black color and cotton is grown very well. Black cotton soils are mud-rich soils shaped in locales (jungles and subtropics) having helpless waste conditions. Such conditions favor the development of such dirt which has montmorillonite earth mineral as the vital … Read more
Soil Nailing is a method to improve the stabilizing slopes and soil improvement. This method is primarily used to bring soil stability where landslides can cause severe problems. This cycle comprises of fortifying the regular ground with firmly dispersed steel or metal bars or segments (i.e nails) grouted in the pre-bored openings and giving front … Read more
What Is Soil Liquefaction? Soil liquefaction is a process in which saturated or partially saturated soil loses its strength and stiffness under the application of earthquake load or sudden rapid loading conditions. Concept Of Soil Liquefaction In normal conditions, soil particles are connected to each other due to contact forces and provide strength to the … Read more
In this article, we will study “stresses in soil”. It is very important for engineers to study the behavior of soil before starting any construction. Stresses in the soil can determine which type of foundation will be provided. Usually, there is two popular theory to calculate stresses in soil. First, we will learn some terms … Read more

Types of Rocks: They are categorized by the minerals including their chemical composition and how it is formed. Rocks are grouped into 3 main categories. … Read more
Various types of footings are used in construction. Footing is the most important part of the structure that transfers loads of a structure to the underlying soil. In this blog article, I will describe the types of footing. Selection of Footings depends upon the following factors: We have listed some common types of footing used … Read more
