Mat Foundation A mat foundation, also known as a raft foundation, is a type of shallow combined foundation which uses a large reinforced concrete slab-on-grade that transfers the entire weight of the structure to the subgrade. It works by dispersing load over much larger area on the ground when compared to discrete shallow isolated foundations. … Read more
Biological stabilization of soil simply refers to the stabilization of soil is achieved through biological means like planting or afforestation or more complex biological processes. The term “soil stabilization” refers to the process of increasing the stability and bearing capacity of the soil using proportion, controlled compaction, and/or the addition of suitable admixtures or stabilizers. … Read more
In-situ Soil testing In-situ soil testing is necessary to obtain the soil property information, to measure groundwater pressure, to gather the moisture content and other important data points. In-situ soil testing can be accomplished in a variety of different ways. Every soil test has its own place and benefit. Following are the in-situ tests which … Read more
Machine foundations and their vibration analysis Analysis and the design of the machine foundations involves careful evaluation of the vibration characteristics of the foundation system. This type of foundation undergoes dynamic loads which develop the vibratory motions which are taken by the soil below the foundation. This effect caused by the vibratory motions on the soil … Read more
Safe Bearing Capacity of Soil (SBC) The relationship between structure and the soil is as old as humans. How often have we wondered about the fact that the soil and the foundation are made up of entirely different constituents, yet create wonders together? The integrity of any structure is limited to the capacity of the … Read more
Sand Compaction Piles Sand compaction piles are one of the potential methods for improving ground stability, preventing liquefaction, reducing settlement and similar applications. This method involves driving a hollow steel pipe into the ground. The bottom is closed with a collapsible plate down to the required depth and then pipe is filled with sand. The … Read more
Retaining wall Retaining wall is structures that is constructed and designed to resist the lateral pressure of the soil. Apart from soil, the lateral pressure is caused by the pressure of liquid, earth filling, sand, or other granular material filled behind the wall after it’s constructed. These walls are key components of transportation structures and … Read more
Vibro Stone Columns To improve the load bearing capacity of in-situ soils and fills, Vibro stone columns are designed and are used. These columns reduce the differential settlements of non-homogeneous and compressible soils which allows the use of shallow footings and thinner base slabs. For the construction of Vibro stone columns, the vibrator is made … Read more
DEEP SOIL MIXING The properties of soft cohesive soils can be improved by mixing of a variety of chemical additives. The addition of lime, fly ash and cement in different combinations can significantly improve the shear strength and compression properties of such soils. Other additives can be used to fix pollutants in place to prevent … Read more
