What is Underpinning?

Underpinning is a construction technique used to repair, strengthen, or increase the depth of an existing foundation by deepening its base to rest on more supportive soil.

When is Underpinning Necessary?

Underpinning may be required in various situations:

• Soil issues or changes
• Foundation flaws
• Changes in building use
• Nearby construction affecting soil stability

Our Underpinning Process

1. Assessment and Planning
   • Conduct a thorough evaluation of the existing foundation
   • Analyze soil characteristics and structural requirements
   • Develop a comprehensive underpinning plan
2. Permit Acquisition
   • Obtain necessary permits from local authorities
   • Ensure compliance with building codes and regulations
3. Excavation
   • Carefully excavate around the existing foundation in phases
   • Maintain structural stability throughout the process
4. Underpinning Method Selection. We employ three primary underpinning methods based on your specific needs:
   • Mass Pour: Cost-effective for heavy loads, involves pouring concrete beneath the existing foundation in sections
   • Mini Piled: Ideal for variable soil conditions, uses deep vertical piles screwed into stable soil
   • Beam and Base: Advanced method using a reinforced concrete beam to transfer load to a new concrete base
5. Foundation Reinforcement
   • Implement the chosen underpinning method
   • Ensure proper load distribution and structural support
6. Quality Control and Testing
   • Conduct rigorous testing to verify the effectiveness of the underpinning
   • Ensure compliance with engineering specifications
7. Site Restoration
   • Backfill excavated areas
   • Restore the site to its original condition

At Stellar Work Construction, we prioritize safety, efficiency, and long-lasting results in all our underpinning projects. Our experienced team uses state-of-the-art techniques and high-quality materials to ensure the stability of your structure for years to come.
