Soil Nailing | Principles | Advantages

Soil-nailing-done-to-protect-the-highway

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 Soil Nailing | Principles | Advantages

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 Vibro Stone Columns | Ground Improvement
