DETERMINATION OF SOIL ABSORPTION CAPACITY
PERCOLATION TEST
Percolation test is done to determine the absorption capacity of soil. This test is important for th

Foundation heave is the movement of expansive soil due to changes in its moisture content. The foundation heave occurs in various patterns like doming, edge, cy

To Determine Particle Size Distribution of Soil by Sieving
The soil is sieved through a set of sieves. The material retained on different sieves is determined.

Hydrometer method is used to determine the particle size distribution of fine-grained soils passing 75 µ sieve. The hydrometer measures the specific gravity of

What is Pad Foundation?
The pad foundations are shallow foundation that take and spread point loads to the soil safely. The pad foundation are preferred if the

The calculation of the number of passes for compactors and lift (soil layer) thickness for soil is critical to attain the required degree of compaction. General

The New Austrian Tunneling Method (NATM), also known as the sequential excavation method, gained recognition during the tunneling operations in the Austrian Alp

What is negative skin friction on piles and pile group?
Negative skin friction is usually a downward shear drag acting on a pile or pile group because of downwa

Microtunnelling is an efficient trenchless technique for the construction of small diameter tunnels. The method is especially useful for laying pipelines beneat

Micropiles are deep foundation used when very limited space or headroom is available for execution with conventional pile rigs. These piles are also called as m
