With more than 30 years of experience, we restore structural stability and help protect your home from further movement.
Underpinning for Foundation Strength and Stability
Underpinning is the process of strengthening and stabilising the foundations of a home, particularly when a concrete slab has cracked, sunk or moved over time. It is often required when adding extra levels or when soil movement has caused structural instability. The process involves carefully excavating around the affected area, supporting the structure with jacks, and pouring reinforced concrete beneath to create a stronger foundation.
When Underpinning May Be Needed
Foundation movement can happen gradually, but the warning signs are often visible inside and outside the home. If left untreated, these issues can worsen over time and lead to more extensive structural damage.
- Cracks in internal plaster walls or ceilings
- Cracking or shifting in brickwork
- Uneven or sinking floors
- Doors and windows that no longer align properly
- Visible movement in external walls or slab edges
Repacking and Re-Supporting Foundations
Repacking involves restoring stability beneath your home by adjusting and re-supporting existing stumps and foundation points. This process helps correct movement and re-establish proper load distribution across the structure. It is a practical solution when foundations have shifted, but full replacement is not required.
Sub-Floor Excavation and Preparation
In some cases, improving access and ventilation beneath the home is an important part of restoring long-term stability. Sub-floor excavation involves removing excess soil and clearing space under the house to improve airflow and reduce moisture build-up. This helps protect timber components and supports the effectiveness of underpinning and restumping work.
Our Foundation Repair Process
Every project begins with a detailed inspection to assess the structural conditions and determine the most suitable repair method. We use proven techniques to ensure accuracy, safety, and long-term performance.
- Inspect existing foundation and sub-floor conditions
- Identify areas of movement or structural weakness
- Install temporary supports and hydraulic jacks
- Complete underpinning or repacking as required
- Restore levels and confirm stability before completion
Preventing Further Foundation Damage
Early intervention is key when it comes to foundational issues. Addressing movement quickly can help prevent more serious structural problems and reduce long-term repair costs. Regular inspections are recommended, especially for older homes or properties built on reactive soil.
Underpinning and Foundation Restoration Frequently Asked Questions
What is the difference between underpinning and restumping?
Restumping involves replacing stumps that support timber floors, while underpinning strengthens concrete slab foundations by reinforcing the ground beneath them.
How do I know if my home needs underpinning?
Signs include significant cracking in walls or brickwork, sinking floors, or doors and windows that no longer align properly. A professional inspection is the best way to confirm.
Is underpinning a permanent solution?
Yes. When completed correctly, underpinning provides long-term structural support by stabilising the foundation and reducing future movement.
