Millions of properties in the UK are affected by subsidence each year, which can lead to significant structural issues if left untreated. (Use our online UK postcode checker to see if your area is prone to subsidence.)
Traditionally, underpinning was the primary solution; however, this approach is often invasive, time-consuming, and costly. Resin injections have since emerged as a highly effective alternative, providing an innovative and non-disruptive method for treating subsidence without the drawbacks of traditional underpinning. In this post, we will explain what resin injections are, why they’re used, and explore 5 reasons why they are a better solution than traditional underpinning for addressing subsidence issues.
What are Resin Injections and Why are They Used?
Resin injections are a minimally invasive method for repairing subsidence by stabilising a property’s foundation. Subsidence occurs when the ground beneath a property sinks or settles unevenly, leading to instability in the foundation. This ground movement can result from various factors, including weak soil conditions, water damage from leaks, nearby tree roots absorbing soil moisture and shallow foundations. As the foundation shifts, it can push walls and floors out of alignment, causing visible cracks and structural displacement.
The resin injection process involves injecting a specialised resin material deep into the ground beneath the property. Once injected, the resin expands to fill cracks and voids, reinforcing the ground and providing essential support to the foundation. This added stability helps to prevent further sinking or settling, offering a lasting solution to subsidence.
Why Resin Injections are Better than Underpinning
Resin injections are rapidly gaining popularity for treating subsidence, particularly as property owners look for quicker, less invasive, and more cost-effective alternatives to underpinning. Below, we share 5 reasons why resin injections are the better choice for addressing subsidence than underpinning.
– No Planning Permissions Required
Resin injections usually don’t require planning permission, unlike many underpinning projects that often need approval. This is because the resin injection process is used to stabilise the ground below the foundation, rather than impacting the foundations themselves. In addition, it is far less disruptive, making it unlikely that they will impact surrounding landscaping or interfere with daily life. This benefit not only saves property owners time and effort in navigating regulatory requirements but also allows for a faster start to the repair process. With resin injections, there is no need to wait for planning permissions to be processed by the relevant parties, allowing subsidence issues to be addressed more quickly before they have the chance to worsen.
– Long-Lasting Solution
They provide a durable, long-lasting solution to house subsidence problems. The resin material used in this method is designed to expand and quickly harden, filling voids and reinforcing the ground beneath the foundation. This creates a stable foundation that can withstand further shifts in soil, offering peace of mind that your property is protected for years to come.
– Cost-Effective
Resin injections offer a cost-effective solution for managing subsidence compared to underpinning. The resin injection process is simpler, faster, and requires fewer resources and engineers, which helps to reduce both labour and material costs. This results in significant savings without any compromise on quality or effectiveness for treating subsidence, making resin injections an ideal choice for those seeking a reliable repair solution at a lower cost.
– Applicable for a Range of Structures
It can be used on a wide range of building structures, from residential homes to large commercial buildings. Their versatility means that, regardless of the design, layout, or age of the property, resin injections can be customised to meet specific needs and effectively address subsidence issues. This flexibility makes resin injections an ideal solution for various types of buildings, particularly those where traditional underpinning may not be suitable or feasible.
– Environmentally Friendly
Not only are they highly effective but also environmentally friendly. This method is non-invasive, requiring minimal digging and causing very little disruption to the surrounding area, which helps preserve landscaping and reduces waste. Additionally, the sustainable materials used in resin injections contribute to a smaller environmental footprint than concrete, which has a high carbon value. The entire resin injection process can often be completed within one to two days, further minimising resource use and environmental impact.
