What Is Subsidence and Why It Happens
Subsidence occurs when the ground beneath a building shifts or sinks, causing the foundations to move and the structure above to become unstable. In Manchester, subsidence is often linked to soil conditions, particularly clay soils that expand and contract depending on moisture levels. During dry periods, clay can shrink, creating voids beneath foundations, while wet conditions can cause it to swell, placing pressure on structures. Other common causes include leaking drains, which wash away supporting soil, and tree roots, which absorb moisture and contribute to ground shrinkage. In areas with a history of industrial use, properties may also be built on made ground, which can settle unevenly over time. Understanding the cause of subsidence is essential before carrying out repairs. At ASRS Ltd, we take the time to assess each case carefully, ensuring that any repair work addresses the root issue and provides a stable, long-term solution.
Signs of Subsidence in Your Property
Recognising the signs of subsidence early can help prevent more serious structural damage. One of the most common indicators is cracking in walls, particularly diagonal cracks that are wider at the top than the bottom. These often appear around windows and doors, where structural stress is most visible. You may also notice doors and windows becoming difficult to open or close, as frames become distorted due to movement. In some cases, floors may become uneven or slopes may develop, indicating that the foundations are shifting. External signs can include cracks in brickwork, gaps between walls and extensions, or tilting structures. These issues can worsen over time if left untreated. At ASRS Ltd, we carry out thorough inspections to determine whether subsidence is present and assess its severity. By identifying the problem early, we can recommend the most appropriate repair method and help prevent further damage to your property.
Our Approach to Subsidence Repairs
At ASRS Ltd, we take a structured and practical approach to subsidence repairs in Manchester. The first step is always a detailed assessment to confirm the cause of the movement and the extent of the damage. Once this is established, we develop a tailored repair plan designed to stabilise the structure and prevent further movement. In some cases, addressing the cause, such as repairing drainage issues or managing nearby vegetation, may be enough to stop the problem from progressing. For more significant cases, structural reinforcement methods such as crack stitching, Helifix reinforcement or underpinning may be required to restore stability. We always aim to use the least disruptive and most effective solution for each situation. All work is carried out to a high standard and in line with UK building regulations. Our goal is to provide a long-term fix that ensures your property remains safe, stable and protected against future movement.
