What is property subsidence?

Property subsidence is a critical concern for both DIY enthusiasts and potential homebuyers. Understanding the risks associated with subsidence can help in making informed decisions when buying a property or maintaining one. This article provides a comprehensive overview of property subsidence, its signs, implications for property purchase, and remediation methods.

1. What is Property Subsidence?

Subsidence refers to the gradual sinking or settling of a property's foundation. This phenomenon can lead to structural damage over time, as the ground beneath the building shifts or compacts. Several factors can cause subsidence, including soil type, presence of underground voids, changes in groundwater levels, and the impact of vegetation. Clay soils, for instance, are particularly prone to changes in volume with moisture levels, leading to expansion and contraction that can affect building foundations.

2. What are the Signs of Property Subsidence?

Identifying subsidence early can mitigate significant structural damage. Key indicators include:

Cracks in walls or floors, especially those that are diagonal and wider at the top.
Doors or windows that stick or do not close properly.
Sloping floors or staircases.
Gaps between walls and floors or ceilings.

It's important to differentiate subsidence cracks from those caused by other factors like temperature changes or settling in new buildings, which are usually minor and evenly distributed.

3. Should I Buy a Property with Subsidence?

Purchasing a property with subsidence can be risky. It may affect the property's value, lead to higher insurance costs, or necessitate expensive repairs. However, a thorough evaluation by a professional can determine the severity of the subsidence and the potential for future movement. In some cases, with proper remediation, properties with subsidence can still be a good investment.

4. How Can I Fix Subsidence Issues with My Property?

Repairing subsidence may involve several strategies, depending on the cause and severity:

Underpinning: Strengthening or stabilizing the foundation by extending it to more stable soil.
Soil Stabilization: Injecting materials like resin into the soil to increase its strength and stability.
Removing or Pruning Vegetation: To reduce soil moisture level changes near the foundation.
Improving Drainage: To manage water flow around the property and reduce soil saturation.

Consultation with a structural engineer or a specialist surveyor is crucial to determine the most appropriate solution.
