Sustainable and eco-friendly, resin injection can usually be completed within one to two days, while underpinning takes several weeks or months. Resin injection causes very little disruption to your property, while underpinning is more invasive and disruptive. Both methods are effective, but underpinning is considered more permanent for severe subsidence or unstable foundations.

Resin Injection vs Underpinning for Subsidence Repairs

Explain more about is resin injection?

First used in the UK back in the 1980’s, resin injection is a minimally invasive subsidence repair method that involves injecting a resinous material into the ground beneath your property. The resin expands and fills any cracks and voids, helping to stabilise the foundation and prevent further subsidence.

There is no requirement for resin injection, no planning permission or insurance claims, we offer a fixed fee service and you can even get a discount if your neighbour(s) from the same street/postcode areas join together for a group price reduction. Resin injection typically will be completed in one working day, we have multiple engineers throughout the UK so our services are very proactive.

When to Choose Resin Injection – Advantages of Resin Injection

Far less invasive than underpinning, resin treatment is so much quicker and hardly disrupts your day. It’s much more affordable than underpinning, less likely to cause damage to your property, and more effective for treating localised subsidence. Soil with a high clay content is particularly susceptible to subsidence, your home will show you tell tell signs of subsidence over time.

Resin injection is a good option for mild to moderate cases of subsidence, properties with difficult access or limited space, properties with sensitive foundations such as those made of brick or stone, and properties with budget constraints.

What is Underpinning and when would I need it?

Underpinning is a more invasive subsidence repair method that involves excavating the ground beneath your property and installing new foundations. This method is more expensive and time-consuming than resin injection, but it may be necessary for severe cases of subsidence.

Underpinning is a good option for severe cases of subsidence, properties with unstable foundations, properties with a history of subsidence, and properties that need to be raised or strengthened.

Advantages of Underpinning – If you’re experiencing subsidence, you may be wondering which repair method is right for you: resin injection or underpinning. Both methods have their own advantages and disadvantages, so it’s important to weigh the pros and cons before making a decision.

Underpinning is more effective for treating severe cases of subsidence, more effective for treating subsidence caused by weak or unstable foundations, and more effective for raising or strengthening a property.

Disadvantages of Resin Injection – For Severe Property Damage

Resin injection may not be suitable for severe cases of subsidence, properties with unstable foundations, properties with a history of subsidence, or for raising or strengthening a property.

Disadvantages of Underpinning – Underpinning is more invasive than resin injection, slower and more disruptive than resin injection, more expensive than resin injection, and more likely to cause damage to your property.

How to Choose the Right Subsidence Repair Method

The best way to choose the right subsidence repair method is to consult with a qualified subsidence engineer. They will be able to assess the severity of your subsidence and recommend the most appropriate repair method for your property. Here are some factors to consider when choosing a subsidence repair method: the severity of the subsidence, the type of foundation your property has, the budget you have available, the timescale you need the repairs to be completed within, and the disruption you are willing to tolerate.

Cracked Walls Can't Be Ignored!

Discovering cracks in your walls is often the first indication of potential structural damage caused by subsidence. While some cracks may be harmless, others can signal sinking or damaged foundations. Ignoring these problematic cracks can lead to further deterioration, ultimately devaluing your property. Subsidence is the sinking or settling of the ground beneath a building. It can be caused by a variety of factors, including poor drainage, clay soil, and mining. When subsidence occurs, it can cause the foundations of a building to move, which can lead to cracks in the walls.
