Unified soil classification system is adopted by ASTM D-2487-98 and IS: 1498-1970 for classification and identification of soils for general engineering purpose. Unified Soil Classification System

The uniformity coefficient (Cu), curvature coefficient (Cc) and the effective size (D10) are the grading characteristics of the soil. These are the geometric properties of a grading curve that desc

Uplift pressure, which is also known as hydrostatic uplift, is an upward pressure applied to a structure that has the potential to raise it relative to its surroundings. It is the condition of

There are two methods of ground improvement or soil stabilization, i.e. by using surface rolling and by using vibro-stabilization methods. While surface rolling method is used for stabilizing or co

Soil instability is the inclination of soil for upward, lateral, or downward movement due to natural factors like pore water pressure, cracking, earthquakes, etc. It is crucial to understand the fa

Foundation is one of the most vital elements of a structure as its safety and performance affect the entire building. Any kind of negligence during the construction of foundations would mean compro

Wet, moist and damp subgrade are classified based on its water content. Varying water content affects the performance of subgrades hugely, therefore, it becomes important to study the behaviour of

Weight sounding test is a form of penetration test conducted at construction sites to assess liquefaction susceptibility, soil profiling, determination of the bearing capacity of shallow

What is Water Content of Soil? The water content of soil is is the ratio of mass of water to mass of soil which is expressed in percentage. Oven Dry Method and Pycnometer Method are commonly used t

A waffle slab foundation, also termed as ribbed slab foundation, is a structure that is plain at the top and has a grid-like system (called the ribs) at the bottom. The ribs are formed due to the p
