Residential Underpinning: Everything You Should Know

A house starts from the foundation, and foundation problems mean risks for the whole house. If the foundation isn’t strong enough for the house anymore, it’s only natural that it would raise concerns. Deeper foundation issues require a strong solution, and that solution usually comes in the shape of residential underpinning. Underpinning a house is a safe and effective way to redistribute the balance by reinforcing the existing foundations. In this guide, we’ll explain what underpinning is, why it may be needed, when it becomes necessary, the common methods used, and what to consider before moving forward.

What Residential Underpinning is and Why Homes Need it

Residential underpinning is a construction process concerned with strengthening the preexisting foundation of a house. This is typically done by extending the foundation deeper or improving its ability to support the weight of the building or provide area with more height. When the original foundation can no longer support the house, residential underpinning is used since it can restore stability, prevent further movement, and protect the long-term structural integrity of the home. There are many reasons as to why a house might need residential underpinning, including:

• Soil conditions changing overtime due to moisture loss, erosion, or poor compaction
• High water table condition
• Tree roots
• Plumbing leaks
• Excavation and nearby constructions/Angle of repose of adjacent property footing
• Weak original foundation

Signs Your Home May Need Residential Underpinning

Not all foundation problems need residential underpinning to be fixed, but there are a few signs that if you notice, your house probably needs underpinning. Of course, it’s always better to get a professional’s opinion on matters such as this. You may need residential underpinning if you notice:

• Large or widening cracks in walls, ceilings, or floors
• Uneven or sloping floors
• Doors or windows sticking or going out of alignment
• Gaps between walls and ceilings or floors
• Visible foundation movement or settlement
• Ongoing foundation issues despite previous repairs

Different Types of Residential Underpinning

There are more than one residential underpinning method. Each one suits a certain soil condition, foundation type, amount of access, and the extent of the problem.

1. Mass Concrete Underpinning: This is one of the most traditional ways. Concrete is poured beneath the existing foundation in sections to make it deeper and stronger. It’s usually used for low-rise residential properties.
2. Beam and Base Underpinning: This method uses reinforced concrete beams placed beneath the foundation, which transfer the load to concrete bases at a lower level. It’s often the go-to choice when foundations need support over a wider area.

Planning Ahead for Residential Underpinning

Before taking action, be sure to take note of some points to consider for residential underpinning. Careful planning and expert guidance can make the process smoother and more predictable. There are several important factors to think about:

• Cause of the problem: Underpinning should address the root cause of foundation movement, not just the symptoms.
• Soil conditions: A soil assessment will help you work out the best way to underpin. sandy soil like beached area is the most difficult soils for underpinning
• Cost and timeline: Underpinning is a big structural project, so it needs proper budgeting and planning. usually underpinning will be happened in 4 stages and non of them is not allowed to be started before completion of previous one and inspection.
• Disruption: Some methods involve digging and causing a bit of a headache inside or outside the home.
• Professional assessment: Working with experienced specialists guarantees that the solution is safe, compliant, and effective.
