Subsidence Management & Repair
At Shire, we understand how unsettling it can be when your property shows signs of subsidence. Whether it’s visible cracks in your walls, uneven floors, or sticking doors and windows, subsidence can affect the structural integrity of your home or building. With over two decades of expertise, we offer comprehensive subsidence repair services to identify the root cause and deliver effective, long-lasting solutions. Our team is here to provide peace of mind and ensure your property remains safe, stable, and secure for years to come.
What is Subsidence and How Does It Occur?
Subsidence refers to the downward movement of the ground beneath a building, causing the foundation to sink or shift. This can lead to cracks in walls, doors and windows that no longer fit, and even damage to the floors. But what causes this shift in the ground?
Subsidence typically occurs when the soil beneath your property becomes unstable. Common causes include:
- Shrinkable soils: Clay-rich soils can expand and contract depending on moisture levels, causing the ground to shift.
- Tree roots: The roots of large trees can draw moisture from the soil, weakening it and causing it to shrink.
- Water leaks: Leaking pipes or drains can wash away soil or change the moisture content, destabilising the ground.
- Old mine workings or voids: In certain areas, historical mining activity can lead to voids that weaken the ground, triggering subsidence.
Without addressing these issues, the damage can worsen over time, leading to significant structural issues. That’s why early detection and professional subsidence management are essential.
How to Spot the Signs of Subsidence
Subsidence is often gradual, and its symptoms can be subtle at first. However, there are a few key signs to look out for:
- Cracks in walls and ceilings: Diagonal cracks, particularly around windows, doors, and corners, are a common indicator of subsidence. These cracks tend to widen over time and can be particularly noticeable when the weather is dry.
- Sticking doors and windows: If your doors and windows are no longer opening or closing as they should, this could be a sign that the foundation is shifting.
- Uneven floors: Sloping or uneven floors, or areas where the floor is sinking, are strong signs that your property may be affected by subsidence.
- Gaps between the wall and skirting boards: As the walls shift, you might notice gaps appearing at the top or bottom of your skirting boards.
If you notice any of these signs, it’s important to act quickly. Early intervention can prevent further damage and potentially save you from costly repairs down the line.
Why Immediate Action Is Crucial
Ignoring the signs of subsidence can lead to more serious issues in the future. If left untreated, subsidence can cause significant structural damage, including:
- Worsening cracks: The longer subsidence is left unchecked, the larger the cracks become, potentially compromising the structural integrity of the building.
- Increased repair costs: Early subsidence issues are often more cost-effective to repair, but as the damage progresses, the cost of repairs increases significantly.
- Decreased property value: Properties affected by subsidence can suffer from a reduced market value, and selling such a property can become difficult or impossible.
- Insurance complications: Subsidence may affect your insurance policy, either by increasing premiums or making it harder to get coverage.
With prompt subsidence repair, we can halt the progression of the damage and protect your property’s value, ensuring a safe living or working environment.
Our Subsidence Repair Solutions
At Shire, we offer tailored solutions to address subsidence issues, from early intervention to full-scale repairs. Here’s how we can help:
Comprehensive Site Investigation & Diagnosis
The first step in addressing subsidence is understanding the cause. Our experts conduct thorough site investigations to assess the extent of the damage and identify the root cause of the issue. This could involve soil testing, foundation inspections, and drainage assessments. Our diagnostic process ensures we recommend the most effective solution for your property.
Structural Monitoring & Crack Mapping
To accurately assess the movement and prevent further damage, we use advanced monitoring systems to track and map cracks in your walls and foundation over time. This allows us to determine whether the subsidence is active and guide our repair strategy.
Underpinning & Foundation Strengthening
For properties with significant foundation damage, we may recommend underpinning. This process involves strengthening the existing foundation by extending it deeper into stable soil, providing a solid base for your property. Underpinning is often required for severe cases of subsidence where the ground has shifted considerably.
Resin Injection & Non-Invasive Stabilisation
In less severe cases of subsidence, we may use resin injection or other non-invasive stabilisation methods. This involves injecting resin or grout into the ground to fill voids and consolidate the soil, stabilising the foundation without the need for major excavation.
Drainage & Moisture Control Solutions
If leaking pipes or poor drainage are contributing to subsidence, we provide drainage repair services to eliminate the water source and prevent further soil erosion. In some cases, we may recommend moisture management techniques, such as tree root removal, to regulate soil moisture levels and prevent future instability.
Tree Root Management
In areas where tree roots are causing subsidence, we offer root management services. This may involve removing problematic trees or managing their roots to prevent them from drawing moisture from the soil, which can cause ground movement.
The Benefits of Professional Subsidence Repair
Addressing subsidence early with the right solutions offers numerous benefits:
- Restored structural stability: Stabilising the foundation prevents further movement, reducing the risk of cracks, shifting, or collapse.
- Cost savings: Timely intervention can prevent more extensive and costly repairs later on, saving you money in the long run.
- Improved property value: Properly repaired properties retain or even increase in value, ensuring they remain insurable and marketable.
- Peace of mind: Our professional subsidence repair services give you the confidence that your property is safe and secure.
Common Causes of Subsidence
Subsidence can be caused by a variety of factors, including:
- Shrinkable soils: Particularly common in areas with clay soils, which contract during dry periods and expand during wet periods, causing movement beneath foundations.
- Water-related issues: Leaking pipes, drains, or water mains can wash away soil or soften it, leading to ground movement and subsidence.
- Tree root activity: Roots from large trees, particularly those planted too close to buildings, can absorb moisture from the soil, causing it to shrink and shift.
- Ground disturbances: Previous excavation, mining, or unstable fill materials can create voids in the ground that lead to subsidence.
Understanding the cause of subsidence is crucial for determining the most effective repair method, which is why a thorough site assessment is essential.
How Our Subsidence Repair Process Works
Initial Assessment & Consultation
We start with a consultation to understand your concerns and inspect visible damage. We then conduct a thorough site investigation to assess the extent of the subsidence and identify the root cause.
Tailored Repair Plan
Based on our findings, we developed a customised repair plan that addresses the cause of the subsidence. This could involve underpinning, resin injection, or other stabilisation techniques, depending on the severity of the issue.
Repair & Stabilisation
Our skilled team will carry out the recommended repairs, using state-of-the-art equipment and techniques. We ensure that the work is completed efficiently, with minimal disruption to your property.
Final Inspection & Ongoing Monitoring
After the repairs are complete, we conduct a final inspection to ensure that the subsidence has been fully addressed. We may also recommend ongoing monitoring to ensure the foundation remains stable over time.
