Safe Bearing Capacity of Soil (SBC) | Ultimate Bearing Capacity | SBC Values | Testing


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

Ground Improvement with Sand Compaction Piles | Advantages

Sand compaction piles

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 | Types of Retaining Walls | Design Considerations

Anchored retaining wall

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 | Ground Improvement

Installation of Vibro Stone Columns by Vibroflot

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 rig with triple mixing tool

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

Pile Foundation | Classification of Pile Foundations | Pile Installation Methods

steel piles installed

Pile Foundation Pile Foundation. Pile foundations are deep foundations used when the site has a weak shallow bearing strata making it necessary to transfer load to a deeper strata either by friction or end bearing principles. Foundations provide support for structures by transferring the load to the rock or layers of soil that have sufficient … Read more

Failure Modes in Rock and Soil Slopes | Slope Failure


Failure Modes Introduction Slope failures are essentially natural hazards that occur in many areas over the world. Popularly known as landslides, slope failures describe a wide variety of mechanisms that cause the outward or downward movement of slope-forming materials like rock, soil or landfills. Landslide can result either from rock failure or soil failure. While … Read more

Ground Improvement by Dynamic Soil Compaction -

Ground Improvement Ground Improvement or Ground treatment is defined as “controlled alteration of the state, nature or mass behavior of ground materials to achieve an intended satisfactory response to existing or projected environmental and engineering actions” Ground Improvement by Vibration Vibration can be used to compact soils and fills. Similar to Vibrating rollers used to … Read more

Negative Skin Friction in Piles: Causes & Design Calculations


What is Negative Skin Friction? Negative skin friction is usually a downward shear drag acting on a pile or pile group due to downward sinking of surrounding soil relative to the piles. This shear drag movements are expected to occur when a segment of the pile penetrates a compressible soil stratum that can consolidate. Downward … Read more
