Is Resin Injection Cheaper Than Underpinning?
If you're dealing with foundation issues, one of the first questions that comes up is: Is resin injection cheaper than underpinning? The short answer is yes—resin injection is often more cost-effective, but it depends on your specific situation.
What Is Resin Injection?
Resin injection (also known as polyurethane resin injection) is a modern ground improvement method. It involves injecting expanding resin beneath your foundation to fill voids, stabilise soil, and lift settled structures.
What Is Underpinning?
Underpinning is a traditional method that strengthens foundations by extending them deeper into stable soil layers. This process usually involves excavation, concrete, and significantly more labour.
Cost Comparison: Resin Injection vs Underpinning
💰 Resin Injection Costs
- Lower labour costs
- Minimal excavation required
- Faster completion (often within a day)
- Less disruption to your property
💰 Underpinning Costs
- Higher labour and material costs
- Requires excavation and heavy equipment
- Can take days or even weeks
- More invasive process
👉 Result: In most cases, resin injection is significantly cheaper than underpinning.
Why Resin Injection Is Often the Better Option
✅ Faster Results
Most jobs are completed in just a few hours.
✅ Less Disruption
No major digging or structural disturbance.
✅ Long-Lasting Solution
Modern resins are durable and resistant to water and soil movement.
✅ Cost-Effective
You save on labour, time, and restoration costs.
When Underpinning Might Be Necessary
While resin injection is highly effective, underpinning may still be required when:
- Structural damage is severe
- Foundations are too weak or deteriorated
- Deep soil instability is present
A professional inspection is always the best way to determine the right solution.
What’s the Best Choice for Your Property?
Every property is different. The most cost-effective solution depends on:
- Soil conditions
- Level of foundation movement
- Type of structure
