Underpinning involves strengthening and stabilizing the foundation of an existing structure. This service is critical when a building's original foundation is no longer strong or stable enough due to subsidence, changes in soil conditions, increased load requirements, or renovations such as basement lowering.
Key Services:
- Site Assessment & Engineering: Comprehensive structural analysis and soil testing to determine the appropriate underpinning method.
- Traditional Mass Concrete Underpinning: Sequential excavation and concrete pouring to deepen and reinforce the foundation.
- Mini-Piled Underpinning: Ideal for restricted access sites or poor soil conditions, using deep-driven or bored piles connected to the existing foundation.
- Beam and Base Method: Construction of reinforced concrete beams to redistribute building loads across new footings.
- Basement Lowering (Bench Footing or Underpinning): Increasing basement ceiling height while reinforcing the structure.
