Foundation & Footing Repairs
Stabilisation and restoration of compromised foundations and footings to correct structural settlement, prevent further movement, and reinstate full load-bearing capacity.

A building’s foundation is its entire structural base — and when it fails, every element above is at risk. Footing movement, settlement, or failure can cause cracks in walls, uneven floors, sticking doors/windows, and in severe cases, progressive collapse. These issues are often caused by soil movement, poor original design, drainage failures, or long-term water ingress.

Atomic Projects approaches foundation and footing repairs with engineering precision, addressing not only the visible symptoms but the underlying cause. Our focus is on stabilising the structure for the long term, ensuring load transfer is re-established and soil conditions are managed to prevent recurrence.

Our Process for Foundation & Footing Repairs

  1. Engineering Assessment
    • Detailed inspection by structural engineers to determine the cause and extent of movement.
    • Soil testing to identify shrink-swell potential, bearing capacity, and moisture variation.
    • Crack monitoring and level surveys to measure active vs historic movement.
  2. Access & Preparation
    • Secure and support structure before commencing works.
    • Excavate to expose existing footings without overloading remaining structure.
  3. Repair & Strengthening Methods
    • Underpinning:
      • Traditional mass concrete underpinning for shallow depth repairs.
      • Steel screw piles or push piers for deep foundations and poor soil conditions.
    • Micropiles: Installed in restricted access areas to provide deep load transfer.
    • Slab Jacking / Resin Injection: For minor slab settlement, lifting and re-levelling concrete floors.
  4. Drainage & Moisture Management
    • Install subsoil drains, ag lines, and stormwater diversion to prevent future soil moisture fluctuations.
    • Improve surface grading to direct water away from the building footprint.
  5. Reinstatement
    • Replace or upgrade footings where original materials are inadequate.
    • Reinstate landscaping, hard surfaces, and finishes with minimal disturbance.

Applications

  • Residential & Multi-Storey Buildings: Addressing settlement cracks and floor level changes.
  • Commercial & Industrial Structures: Heavy load environments requiring higher capacity footings.
  • Heritage Buildings: Foundation stabilisation with minimal impact to original fabric.
  • Flood & Storm-Damaged Sites: Recovery of footings after erosion or scouring events.

Why Atomic Projects for Foundation & Footing Repairs

  • Integrated Solutions: We combine engineering, geotechnical, and construction expertise for a single point of responsibility.
  • Minimal Disruption: Systems designed for occupied buildings to minimise downtime.
  • Future-Proofing: Every repair includes drainage and soil management considerations to avoid repeat issues.

Foundation and footing repairs are a structural safety priority. Done correctly, they stop progressive damage, extend the building’s lifespan, and protect the owner’s investment.
