How much does it cost to fix subsidence in Ireland?
Discovering subsidence in your home can feel overwhelming, and one of the first questions most people ask is “how much will it cost to fix subsidence?”
The answer depends on the severity of the problem, the type of property, and the repair method used. Traditional options like underpinning and piling can be expensive and disruptive, while modern solutions such as resin injection are often faster and far more cost-effective.
Typical subsidence repair costs
Rather than estimating unpinning costs by overall property size, a more accurate calculation is to base the price on the number of linear metres (LM) of wall that require treatment, and the depth needed below the foundation. For a 6 linear metre wall requiring treatment, the costs for each method would be:
Mass Concrete - £1,000 - £1,500
Mini Piled Underpinning - £1,500 - £2,500
Resin Injection - £800 - £1,500
The hidden costs of traditional methods
When choosing piling or mass concrete underpinning, there are often extra costs to consider, such as:
Surveys, inspections, and building control applications
Party wall agreements for terraced or semi-detached properties
Alternative accommodation for your family while work takes place
Landscaping repairs around the home after excavation
Weeks of disruption to daily life
Because Mainmark’s resin injection methods are fast, non-invasive, and completed without major excavation, many of these extra expenses can be avoided completely.
Why do subsidence costs vary so much?
Traditionally, the main way to repair subsidence was underpinning with mass concrete or piling. These methods involve digging beneath the foundations, which makes them costly, messy, and time-consuming.
Mainmark’s modern approach avoids this disruption. With Teretek® resin injection, small holes of around 16mm in diameter are drilled under the foundations. Through these, expanding resin is injected to fill voids, strengthen the ground, and gently lift the property if required. For larger or more complex sites, our JOG computer-controlled grouting delivers the same result with precision.
Our solutions not only stabilise the structure but also:
Strengthen the soil beneath the home
Improve load-bearing capacity
Reduce the risk of future ground movement
Once complete, only minor repairs would be needed, such as sealing the small injection points or patching existing cracks. Most projects take a matter of days, if that, which helps keep costs and stress to a minimum.

Benefits of Mainmark’s subsidence solutions
Our dedicated team of experts is committed to understanding your unique needs and objectives, working closely with you to develop and execute.
Fast
Most homes are treated within days
Cost-effective
Typically costing far less than underpinning or piling
Non-invasive
Small injection holes, no major excavation
Environmentally safe
Materials are inert and non-toxic
What happens with unlevel driveways, floors and hardstand areas?
After Mainmark’s treatment, uneven and unlevel surfaces are brought back into alignment as the ground is strengthened and re-supported beneath. In most cases, only light cosmetic touch-ups are needed, such as filling small injection points or patching minor cracks.
