Soil Improvement Method Based on Soil Types

💡 What is the soil improvement?
In the context of construction projects, soil improvement refers to the techniques and processes used to enhance the engineering properties of soil to make it more stable, supportive, and suitable for construction activities.

💡 How to Select Soil Improvement Method Based on Soil Types?

🔸Soil Replacement.
The soil replacement method is the process of removing existing soil from a construction site and replacing it with new or different soil materials. It is a technique used to improve the properties of the soil at a construction site to meet specific engineering requirements or address soil-related issues.

🔸Water Removal
The water removal method is appropriate for sites with an underlying compressible cohesive soil layer. There are four techniques by which water is removed from the soil to improve its strength:
🌿 Trenching technique
🌿 Preloading technique
🌿 Preloading with vertical drain
🌿 Electro-osmosis

🔸 Site Strengthening Methods
There are a number of site-strengthening methods from which engineers can select a suitable technique based on equipment availability, cost, local experiences, etc. Different types of site strengthening methods are described below:
🌿 Dynamic Compaction
🌿 Vibro-compaction
🌿 Vibro-replacement
🌿 Vibro-displacement

🔸 Grouting
Grouting is the injection of grout into the ground to fill underground voids, joints, and fractures and consequently improve soil strength.
🌿 Injection of Grout
🌿 Deep Mixing

🔸Thermal Method
Heating and freezing are two techniques to improve the soil properties. The former is suitable for cohesive soil, whereas the latter is applicable for soil types below the groundwater table and cohesive soil above the groundwater table.

🔸 Geosynthetics
The geosynthetic materials can be used for erosion control, filter, drains, water barrier, and soil reinforcement. It is an effective filter for all soil types and reinforcement for soft soil.
