What is Ground Heave?
Ground heave refers to the upwards movement of soil beneath a property’s foundations. This movement can occur due to various factors, including changes in moisture content and the presence of certain types of soil.
When the ground beneath a property expands or rises, it can exert considerable pressure on the foundations, leading to structural damage. This can be a major concern for homeowners, as it can significantly impact the value of their property and cause complications during the selling process.
The Science behind Ground Heave
Ground heave is typically caused by the expansion of clay soils when they absorb moisture. Clay has the unique property of expanding and contracting with changes in moisture content. When clay soils become saturated with water, they expand, exerting pressure on the foundations and causing them to lift.
It’s worth noting that not all soil types are prone to ground heave. Sandy or gravelly soils, for example, are less likely to experience this issue as they don’t expand significantly when wet. However, homes built on clay soils, such as many properties in the North East of England, are particularly susceptible to ground heave.
The Role of Trees in Ground Heave
While clay soils are the primary culprit of ground heave, trees can also play a role in exacerbating this issue. Tree roots seek out moisture in the soil, and if they grow near or under a property, they can cause the soil to dry out unevenly. This imbalance in moisture content can lead to differential movement of the ground, resulting in ground heave.
In some cases, homeowners may notice that ground heave occurs after trees have been removed from the property. This is because the tree roots, which previously drew out moisture from the soil, are no longer present. As a result, the clay soils can become excessively wet, leading to expansion and ground heave.
The Causes of Ground Heave
Now that we understand what ground heave is, let’s dive deeper into the causes. Here are the primary factors that contribute to ground heave:
1. Clay Soils
As I mentioned earlier, clay soils have a high water absorption capacity, which makes them prone to expanding and contracting. When clay soils become saturated with water, they can expand significantly, causing the ground to heave.
In the North East of England, where I’m based, clay soils are prevalent. It’s estimated that around 60% of the properties in this region are built on clay soils, making ground heave a common concern for homeowners.
If you suspect that your property is built on clay soils, it’s essential to take steps to monitor and manage ground movement.
2. Changes in Moisture Content
Changes in the moisture content of the soil can also trigger ground heave. Clay soils absorb water readily, so during periods of heavy rainfall, the ground can become saturated. This excess moisture causes the clay to expand, leading to upward movement and potential damage to the property’s foundations.
Conversely, during dry spells or when trees and plants draw out moisture from the soil, the clay can shrink and contract. This shrink-swell cycle can cause the ground to settle, resulting in subsidence issues.
It’s crucial to ensure proper moisture management around your property. This includes maintaining adequate drainage systems, avoiding over-watering gardens close to the property, and managing nearby vegetation that may impact soil moisture content.
3. Tree Influence
As mentioned earlier, tree roots can contribute to ground heave through their impact on soil moisture content. Trees absorb water from the soil through their roots, and in doing so, can cause the soil to dry out unevenly.
If you have large mature trees near your property, it’s important to monitor their proximity to your home’s foundations and take necessary precautions to avoid excessive drying of the soil.
4. Historical Mining Activity
In some areas of the UK, historical mining activity can cause ground heave issues. Subsidence caused by mining can lead to ground instability and movement, which can affect nearby properties.
It’s important to be aware of any historical mining activity in your area when considering property purchases or assessing the risk of ground heave.
Now that we’ve explored the causes of ground heave, let’s move on to the next section: Signs of Ground Heave.
Signs of Ground Heave
So, you’ve heard about ground heave and you’re concerned that it could be affecting your property. But how do you know if you’re experiencing ground heave or if it’s just a normal settlement of the soil? In this section, I’ll discuss some common signs that indicate the presence of ground heave.
1. Cracks in walls and floors: One of the most obvious signs of ground heave is the appearance of new or widening cracks in your walls, floors, or ceilings. These cracks can be vertical or diagonal and may be wider at the top than the bottom. Keep an eye out for cracks that are greater than 3mm in width, as this could be a sign of significant ground movement.
2. Uneven or sloping floors: If you notice that your floors are no longer level or have started to slope, it could indicate ground heave. This can make it difficult to lay new flooring or can even affect the structural integrity of your property.
3. Jammed doors and windows: As the ground heaves, it can cause the frames of doors and windows to become misaligned, making them difficult to open or close. If you find that doors and windows are sticking or are unevenly hung, it could be due to ground heave.
4. Fences and walls leaning or tilting: Ground heave can put pressure on boundary walls and fences, causing them to lean or tilt. This can not only be unsightly but also pose a safety risk.
5. Displaced or cracked paving: If you have noticed that your patio, driveway, or garden paths have become uneven, sunken, or cracked, it could be due to ground heave. The movement of the soil can cause the ground to shift underneath the paving, leading to these visible changes.
6. Changes in drainage patterns: Ground heave can also affect the drainage around your property. Look out for standing water, damp patches, or changes in the flow of water in gutters, downpipes, or drains. These could be a result of the ground heave altering the natural drainage paths.
It’s important to note that these signs can also be indicative of other issues, such as subsidence or settlement. Therefore, it’s always a good idea to consult with a qualified structural engineer or a professional surveyor who can assess the specific situation and determine the cause of the problem.
As a property expert, I always advise homeowners to be proactive when it comes to detecting and addressing signs of ground heave. Ignoring these signs or delaying action can lead to further damage to your property and potentially impact its value.
To help you better understand the severity of the ground heave issues, I’ve compiled a table below that categorizes the signs based on their severity and provides an indication of the potential impact on property value:
