Subsidence means that gradual sinking or caving in of an area of land beneath your property. As well as this, it is possible for a ground heave to happen, which means that the land beneath a property begins to rise.
Neither are very convenient at all.
Property subsidence can cause a lot of structural damage to your residential or commercial plot, however, there are many ways to help prevent subsidence in the first place.
We outline the causes, and warning signs as well as some of the ways that you can avoid damaging effects if there is a ground heave or subsidence.
Subsidence can also be caused by something as inconspicuous as traffic or nearby construction work. Poor or faulty drainage can also cause subsidence.
The risk of subsidence doesn’t mean that you can’t build a property on that land, but it is an important factor to consider.
If you want less risk and more solidity with your project, then it might be worth ensuring that there is minimal risk of subsidence before you buy and build.
The main causes of subsidence can be resolved relatively simply:
If subsidence is minor then it is often not really anything to worry about, however, if you own a property and you experience major subsidence, then this needs to be resolved as a matter of urgency.
If you experience subsidence in your property then there are a number of ways to treat it.
The most expensive treatment is underpinning. This means that a solid foundation is laid below ground to support or strengthen the foundations of your property.
This will usually have to be done if your foundations are shallow or if you have a major case of subsidence.
To avoid being stung with costs of treating subsidence, it can be a good idea to seek out some insurance for your home.
When considering any kind of building work or property development, it’s important to seek professional advice.
Make sure that your costs can be covered, or that you have the right finance option for you. For more about the property finance lending process, click here.
Before you buy a plot of land to build on, you will need a surveyor. They will check the area for pre-existing flood or subsidence risks.
A property survey is carried out in 3 steps.
