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
Blasting Technique for Ground Improvement Blasting is the use of buried explosives to cause the densification of loose cohesion less ground. The principal is that the blasting of explosives in a predetermined pattern causes liquefaction, followed by the expulsion of pore water and subsequent densification of the ground. Blast densification is being utilized for more … 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
Micro pile Micro-piles are piles molded on the spot to serve as deep foundations and highly tensioned stress along the shaft, composed of sand and cement mortar and thoroughly reinforced throughout its length. Micro-piles are employed in highly compact or consistent ground or in the ground where bedrock or rocky formations are found, in which … Read more
Rapid Impact Compaction Rapid Impact Compaction is a shallow ground improvement and densification technique. This method densifies shallow, granular soils, which repeatedly strike an impact plate on the ground surface using a hydraulic hammer. The energy is transferred to the underlying loose soils and regroups the particles into a denser formation. The impact locations are … 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
Dynamic compaction of Soil Dynamic compaction is a ground improvement technique in which a drop weight is used to densify the soils and fill materials. The drop weight is typically made of steel and is lifted by a crane and repeatedly dropped onto the ground surface. The vibrations that are resulted from the repeated drops, … Read more
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
