Soil Nailing Soil nailing is a ground improvement technique which is used to reinforce soil to make it more stable. Soil nailing is used for slopes, excavations, retaining walls etc. to make it more stable. The faces of steep slopes are usually protected by shotcrete and mesh for temporary works and by either cast-in-place concrete … Read more
Reinforced soil is the combination of compacted earth fill with tensile reinforcement to create an earth structure. The properties and performance of this earth structure depend on the bonding between the soil and reinforcement. The layout of reinforcement is done between the layers of compacted earth fill, which is an essential part of the construction … Read more
Factors affecting Compaction of soil Compaction of the soil is the process where the dry density of soil is increased by reducing air content or air voids present in the soil. This process is an essential part of the construction of any structure, as it strengthens the soil. Many factors influence the degree with which … 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
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
Soil Pre-Compression Soil Pre-compression is one of the ground improvement technique which compresses the ground under an applied pressure before placing or completing the structural load. Pre-compression is performed in following two ways: Ground precompression is achieved by pre-loading, which requires placement and removal of earth, water, or some other dead load, before construction, similar … 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
Wick drains & Vertical Soil Drains Wick drains, also called Prefabricated Vertical Drains, are installed in soft soils in order to accelerate consolidation of the soil by providing additional drainage paths for pore water to escape. Other names and variations of this technique are: deep drains, sand drains, sand wicks, band drains, pre-fabricated band-shaped drains. … Read more
