Ground Improvement
Services We Provide :
A . Grouting Techniques
Injecting materials into soil or rock to fill voids and increase strength.
- Permeation Grouting
- Low-viscosity grout injected under pressure, fills pores without disturbing soil.
- Used For: sands, gravels, fissured rock.
- Compaction Grouting
- Thick grout bulbs injected under pressure to displace and densify surrounding soils.
- Used For: settlement correction, underpinning.
- Jet Grouting
- High-pressure jets of water-cement mix erode and replace soil to form soil-cement columns (2–6 ft diameter).
- Used For: foundations, cutoff walls, underpinning.
- Fracture (Fissure) Grouting
- Creates fractures in stiff clay or rock and fills them with grout to improve drainage or strength.
B . Inclusion Methods
Introduce reinforcing elements or columns into the ground.
- Stone Columns (Vibroreplacement)
- Columns of compacted gravel installed via vibroflot.
- Increases strength, reduces settlement, and improves drainage.
- Effective in soft clays and sands.
- Deep Soil Mixing
- Mixing soil in situ with cement or lime slurry using rotating augers.
- Forms soil-cement columns for strength and stiffness.
- Used under embankments, tanks, and foundations.
Ground Improvement
Ground improvement refers to a set of engineering techniques used to enhance the properties of soil or rock — such as strength, stiffness, density, or permeability — to make it more suitable for construction.
It’s a key part of geotechnical engineering, especially when natural soil conditions are weak, compressible, or unstable.
Ground improvement modifies the engineering behavior of in-situ soils to:
- Increase bearing capacity
- Reduce settlement
- Improve stability
- Control groundwater or permeability
- Mitigate liquefaction potential
- Allow use of marginal soils for construction
