Stone Column (SC) #groundimprovement (a.k.a. “Aggregate Piers”) is a widely used and accepted method for increasing allowable #soil bearing capacity while controlling structural settlement to tolerable levels. First used nearly 100 years ago, the vibroflot (a powerful, down-hole radial vibrator) is commonly used to install stone columns using any one of numerous procedures that have been perfected over time. Shown below is a Dry Bottom Feed rig by OMS Pile Driving Equipment GmbH.. Using stone columns, clay soils are reinforced while granular soils are both compacted at depth and reinforced. The result is that #structures can be supported on standard shallow foundations in lieu of more costly and labor-intensive #deepfoundations. Garbin GeoStructural Group provides expert #design for stone columns and many other ground improvement systems. Our designs are optimized and construction-ready and prepared almost exclusively for general #contractors or the specialty contractors who perform the installation. We also offer bid assistance, engineering support during construction, review of quality control documentation, and preparation of final as-built drawings. Licensed in 39 states, we are ready to help you with your #groundengineering needs. We have the #expertise and #experience to get you started on a solid foundation.

Voids are caused by substandard concrete construction and a number of factors such as leaking or broken utilities, poor compaction of the subgrade, and/or poor drainage of the subgrade. They are commonly found in large concrete slabs, below roadways, and bridges within block walls. If this is something your property is experiencing too then make haste to have them surveyed. Our Xradar™ trained technicians carry out a full scan of the area where voids are suspected and produce a void map outlining the presence of any suspected voids. Curious how we did it?

Welcome to #GeoFactFridays! Did you know❓ Geosynthetics are known for their high strength-to-weight ratio, offering significant structural reinforcement with minimal material mass, which is especially beneficial in projects where weight restrictions or transportability are factors to consider. For example, consider mechanically stabilized earth (MSE) walls for highway and railway embankments. In these projects, geosynthetic reinforcements such as #geogrids are used to provide tensile strength to the soil structure.  By incorporating geogrids into the soil layers of the embankment, engineers can create a stable and durable structure without the need for massive amounts of traditional materials like concrete or steel. Overall, the high strength-to-weight ratio of #geosynthetics allows engineers to design and construct efficient and sustainable infrastructure solutions that meet both performance and logistical requirements.

Cool and educational on The construction of vertical circular shafts is an art that requires geotechnical engineering design for the drilling and excavating of a cylindrical passage through soil or rock. This process requires specialized machinery like drill rigs or excavators to ensure the proper completion of the work, for the structural stability of the lining, which is usually concrete. Shafts serve for various purposes, including ventilation, access, or water extraction in underground projects #construction #art #design #engineering #geotechnicalengineering #education 🎥 by Geologando

Mechanical #compatibility refers to the ability of rigid inclusions (#stone column , #rigid columns) to effectively interact with the surrounding soil, transferring loads and accommodating deformations without inducing excessive #stress or #settlement differentials. Stiffness matching between soil and rigid inclusions plays a critical role in various geotechnical engineering applications, particularly in ground improvement techniques. The goal is to ensure compatibility between the stiffness of the surrounding soil and the stiffness of the inclusions, thereby optimizing load transfer and minimizing settlement. Achieving this balance requires careful consideration of the stiffness ranges of both the soil and the inclusions. Generally, the stiffness of the soil ranges from a few kPa for soft clays to several kPa for dense sands, while rigid inclusions such as stone columns or concrete piles can have stiffness ranging from hundreds to thousands of kPa. Proper selection of the stiffness of the inclusions relative to the surrounding soil is crucial to enhance overall ground performance. Selecting the modulus of elasticity is considered an important factor in design for several reasons: Improved Load Transfer Enhanced Bearing Capacity Minimized Differential Settlement Controlled Lateral Displacement Long-Term Performance Cost Savings. The following picture shows the settlement of the types of columns based on their stiffness For more: Han J, Gabr MA.

Sprayed concrete, also known as shotcrete, is extensively utilised in tunnelling due to its versatility and efficiency in providing immediate structural support. It is applied pneumatically, allowing for rapid and flexible placement on uneven or complex surfaces, which is essential in the dynamic environments of tunnel construction. This method is particularly advantageous for stabilising excavated tunnel faces and lining tunnel walls, offering a quick hardening solution that enhances safety by reducing the risk of collapse. Additionally, sprayed concrete can be reinforced with steel fibers or mesh, increasing its load-bearing capacity and durability, making it an invaluable technique in both temporary and permanent support systems in modern tunnelling projects.
