What is a Pile Foundation ? Pile foundations play a vital role in structures, by transferring the structural load to the solid ground below the surface. Elongated and slender elements, piles transmit the load to deeper, high-bearing capacity soil or rock layers, bypassing weaker, shallow soil. Typically, construction materials for piles include wood, steel, or … Read more
In the ever-evolving world of construction and engineering, the safety and stability of structures remain a paramount concern. Beneath awe-inspiring skyscrapers, elegant bridges, and humble dwellings, a world of soil diligently supports these magnificent creations. But how can we be sure of the ground’s capability? One of the essential tests employed for this purpose is … Read more
The fineness modulus of a fine aggregate is defined as an index number that indicates the average or mean size of the sand particles. It is determined by carrying out the sieve analysis test using standard IS sieves. The fineness modulus is an estimate of the amount of aggregate required to proportion mix designs; it … Read more

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
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
