Permeation Grouting

SOIL STABILIZATION With the grand scope and significant costs embraced by large-scale civil undertakings, the condition of the soil around and under the project is a risky component that demands careful consideration. Improving the performance of the soil with injectable grouts is a standard solution for a difference of geotechnical needs. In the case of walls, earthen dams, and in-place waste encapsulation, the soil itself serves as the basic media. In other projects, such as subway and mining tunnels, vertical beams, below-ground structures, and waste and compact ponds, injected grout serves to stabilize, increase, and curtain-off groundwater, rendering such projects viable in most any soils-structure condition. Permeation Grouting is the most popular and oldest form of soil grouting. The technique consists of digging a hole in the soil, including an injection pipe into the ground and then pumping any number of liquefied materials into the problem area. The hole is drilled, wh...

Soil Stabilization Methods with Different Materials

Different types of soil stabilization have been performed for thousands of years below are the basic Soil Stabilization: Soil Stabilization with Cement: Soil-cement can be mixed in place or a central mixing plant. Central mixing plants can be used where borrow substance is required. The mixed soil-cement is then hauled to the job site and spread on the prepared subgrade. Mechanical: This is mainly the oldest type of soil stabilization. Mechanical solutions involve bodily changing the property of the soil somehow, to affect its scale, solidity, and other characteristics.  This is probably the most popular and most natural method for soil stabilization. This is also the common and oldest way for compaction. The process of mechanical stabilization involves physical force on the soil. This helps to change the physical properties of the soil. The most common process in the mechanical method is dynamic compaction.  It removes the deformation of the soil and makes it uniform ...

Uses and Applications of Soil Stabilization

There are three purposes for soil stabilization .  The first one is strength improvement.  This increases the strength of its load-bearing capacity and the purpose is for dust control.  This is done to eliminate or lighten dust, generated by operation of equipment and aircraft during dry weather or dry climates.  The third purpose is soil waterproofing, protect the natural or constructed strength of a soil by preventing the entry of surface water. Typical uses and applications of soil stabilization include Piling mats, Embankment stability, Road construction, Car parks, Foundations for floor slabs, Highway pavement construction, Airport runways, taxiways. Applying cement to soil increases soil strength, decreases compressibility, reduces swell potential, and increases durability. Cement-Stabilized soils are typically used as a stabilized subgrade or road base, but not a surface, except possibly for low-speed roads and parking lots primarily because the material...

Sinkhole Remediation

Sinkholes can occur when water or other forces that displace underground soil, weakening the soil's overall integrity in certain areas. As you might guess, this a severe issue for buildings and houses. When density "gaps" is created in the soil beneath structures, they can sink—slowly, or sometimes dramatically, caused damage. Many types of soil can see changes with compaction grouting . Compaction grouting is used for stabilization and densification as well as void filling. This method is used to fill the voids in the ground around and under your residence providing foundation reinforcement and can be used for sinkhole repair. How Does Compaction Grouting Work? The primary purpose of compaction grouting is to increase the load the soil can bear by adding material to the lower soil layers. To do this, we utilize a limited access drill to drill to the sufficient base. Next, a thick cement mixture is pumped into the ground under high pressure. The soils are compact...

Pros and Cons of Jet Grouting

At present, ground modification improvement is a significant activity, which builds the pedestal for high-quality and strong infrastructures. By the side change in technology in various fields it is apparent that infrastructure needs to improve. Today, slowly but surely people are demanding for the building that may put away from the temper of earthquakes. Now it helps in providing a level of support from the watery loam for the period of the earthquake. These technologies are also serving in tumbling the errors unswerving during the building of houses and foundations. Common advanced technologies include jet-grouting , intrusion grouting, Vibro-floatation, mini-piles, and wick drains. Let us consider about jet grouting, their characteristics, mechanism, and advantages. The grout is introduced at high speed, which enables the jet grouting procedure to destroy the usual surrounding substance of the soil and create through the mixing of the preservative with the in-situ soils a ...

Soil Improvement

In improving soil we need to know the three basic types of soil - Sandy, Clay, and Silt. First, is Clay-based soil causes problems by holding the water and being too dense to our work. Second, Sandy soil allows water to drain too easily which washes out nutrients. Third Silty soil also allows water to wash through it too fast. The difference with sandy soil is when it is dry, the silty soil is powdery in texture and prone to wind damage. Below are the techniques that involve changing soil characteristics by a physical action, such as vibration, or by the inclusion or mixing in the soil of a stronger material. The process will increase the load-bearing capacity and/or the shear strength, reduce both absolute and differential settlements or in some instances, accelerate them, to mitigate or remove the risk of liquefaction in the event of an earthquake or significant vibrations. An improvement in the compaction properties of the soil will give maximum dry density drops, wh...

What is compaction?

Soil compaction occurs when soil bits are compressed together. Reducing pore space between them. A compacted soil has a decreased rate of both water infiltration and drainage. This is because large pores more effectively move water downward through the soil than smaller pores. Besides, the transfer of gases slows down in compacted soils , causing an increase in the likelihood of aeration-related problems. Soil compaction increases soil strength and it is the ability of soil to resist being moved by an applied force – a compacted soil also means roots must exert greater force to penetrate the compacted layer. At the start of digging, architects can start to learn about the soil, dirt, and clay, and whether or not they predict running into problems or obstacles. One common problem is unstable soil and this basically means that the dirt is too soft to provide a sufficient base for paving installation. When this happens, pavers must find an alternative solution to get the job done rig...
