Ground Improvement & Stabilization
Before building on weak or unstable soils, ground stabilization in DR Congo is essential to enhance strength and ensure long-term stability. These techniques improve soil properties to support structural loads, reduce settlement, and increase overall safety.
- Strengthens weak or loose soils
- Reduces settlement and enhances load-bearing capacity
- Supports long-term structural performance
What is Vibro-Compaction & Vibro-Replacement?
Vibro-Compaction is a technique used to densify loose granular soils by inserting a vibrating probe into the ground. This method improves soil strength and stability by rearranging particles into a tighter configuration. Vibro-Replacement, often used in softer soils, involves creating stone columns that act as reinforcements to support structures and reduce settlement. Both methods are effective in improving load-bearing capacity and mitigating the risk of liquefaction.
What is Dynamic Compaction?
Dynamic Compaction is a ground improvement technique that involves dropping a heavy weight from a significant height repeatedly onto the ground surface. The energy from the impact travels deep into the soil, compacting it and improving its load-bearing capacity. This method is especially useful for large sites with loose, granular, or fill materials, and is a cost-effective solution for enhancing ground performance before construction.
What is Grout Injection?
Grout Injection is a method used to strengthen soil and control groundwater by injecting specialized grout mixtures into the ground. This process fills voids, binds loose particles, and enhances the soil’s structural integrity. Depending on the application, different techniques like permeation grouting, jet grouting, or compaction grouting can be used. It’s ideal for stabilizing foundations, sealing tunnels, and improving soils beneath existing structures.
