That sinking patio slab that’s become a trip hazard, or the uneven driveway that pools water every time it rains—these frustrating problems don’t require the expense and disruption of complete replacement. Concrete lifting represents the advanced, modern solution that fixes sunken concrete issues without the cost, mess, and extended downtime of demolition and re-pouring. This innovative technique transforms problematic slabs back to their original level quickly, affordably, and with minimal disruption to your property.
What is Concrete Lifting? The Modern Approach
Concrete lifting is a precision engineering process used to raise and re-level sunken concrete slabs by injecting structural material underneath them. Rather than accepting uneven surfaces or facing expensive replacement costs, this technique addresses the root cause of settling whilst restoring the slab to its proper position.
The modern industry standard employs high-density polyurethane foam injection, representing a significant advancement over older repair methods. This polyurethane concrete raising technique delivers superior results through advanced materials science, providing stronger, more durable repairs than traditional approaches.
How Polyurethane Concrete Lifting Works: A Clean & Quick Process
Understanding the concrete lifting process reveals why this method has become the preferred choice for professional slab jacking UK-wide. The technique follows a precise, minimally invasive approach that respects both your property and your time.
Step 1: Small Holes are Drilled Technicians drill strategically placed holes through the sunken slab, each approximately the size of a 5p coin. These tiny access points contrast dramatically with the large, disruptive holes required by older repair methods, minimising aesthetic impact on your concrete surface.
Step 2: Polyurethane Foam is Injected A specialised two-part polymer mixture is injected through the small holes using precision equipment. This liquid polyurethane immediately begins its chemical reaction process upon contact, preparing to expand and harden beneath the slab.
Step 3: The Slab is Gently Lifted The polyurethane foam expands beneath the concrete, simultaneously filling voids and gently lifting the slab back to its original level. This controlled lifting process allows for precise height adjustments, ensuring perfect levelling without over-correction or damage.
Step 4: Holes are Patched The small access holes are sealed with colour-matched cement compound, making them virtually invisible upon completion. The entire repair blends seamlessly with the existing concrete surface.
The Key Benefits: Why Lift When You Can Replace?
Concrete lifting delivers compelling advantages that make it the smart choice for how to fix sunken concrete slab problems across residential and commercial applications.
Far More Affordable Concrete lifting typically costs roughly half the price of demolition and replacement. You avoid disposal fees, new material costs, and extensive labour charges whilst achieving results that match or exceed replacement quality.
Incredibly Fast Most concrete lifting projects complete within hours rather than days or weeks. The polyurethane cures rapidly, allowing immediate use of the repaired surface. No waiting periods for concrete to cure or weather delays that plague replacement projects.
Minimal Disruption The process requires no loud demolition, heavy machinery access, or landscape destruction. Your garden beds, adjacent structures, and property features remain completely undisturbed throughout the repair process.
A Durable, Long-Term Fix High-density polyurethane foam is waterproof, non-erosive, and incredibly strong. Unlike traditional mudjacking materials that can wash away over time, polyurethane provides permanent void filling that prevents future settling issues.
Is Concrete Lifting Right for Your Project?
Concrete levelling techniques work excellently for numerous common applications where settling or void formation has created uneven surfaces.
Sunken Driveways benefit enormously from lifting, eliminating water pooling and vehicle scraping whilst restoring smooth access to your property.
Uneven Patios & Paths become safe, attractive outdoor spaces again, removing trip hazards and drainage problems that compromise both safety and aesthetics.
Cracked Garage Floors can be lifted and stabilised, preventing further cracking whilst creating level surfaces for vehicle parking and storage.
Warehouse Floors and commercial surfaces often require lifting to maintain operational efficiency and meet safety standards for heavy equipment and forklift operations.
Pool Surrounds particularly benefit from lifting, as the waterproof polyurethane prevents water infiltration that commonly causes ongoing settling issues.
A Quick Word on Mudjacking vs Polyjacking
Traditional “mudjacking” represents an older concrete lifting method using heavy cement slurry pumped beneath slabs. Whilst still occasionally used, this approach requires larger holes, uses heavier materials that can contribute to future settling, and lacks the waterproof properties essential for long-term success.
Modern mudjacking vs polyjacking comparisons consistently favour polyurethane foam due to smaller injection holes, lighter weight that reduces future settling risks, waterproof characteristics that prevent washout, and faster cure times that minimise project disruption.
Conclusion
Concrete lifting isn’t merely a repair technique—it’s a smart, efficient, and modern engineering solution that saves time, money, and hassle compared to traditional replacement approaches. By addressing the underlying void issues that cause settling whilst precisely restoring level surfaces, concrete lifting delivers lasting results that often outlast the original installation.
Whether you’re dealing with a problematic driveway, an uneven patio, or commercial flooring issues, concrete lifting represents the clear choice for efficient, cost-effective concrete levelling. This innovative approach transforms concrete lifting cost considerations from major capital expenditures into manageable maintenance investments.

Frequently Asked Questions
How long does concrete lifting last? Professional polyurethane concrete lifting typically lasts 20-30 years or more when properly executed. The waterproof, non-erosive properties of high-density foam prevent the washout and settling issues that affect older repair methods, providing genuinely permanent solutions.
Can concrete lifting fix large cracks in my slab? Concrete lifting addresses settling-related cracks by stabilising the slab and eliminating further movement. However, structural cracks may require additional repair techniques. Professional assessment determines the most appropriate combination of treatments for your specific situation.
How much does concrete lifting cost compared to replacement? Concrete lifting typically costs 40-60% less than complete slab replacement. Exact savings depend on project size, access conditions, and local material costs, but the technique consistently delivers substantial cost advantages whilst achieving equivalent or superior results.
Is my concrete suitable for lifting? Most concrete slabs are excellent candidates for lifting, provided they remain structurally sound. Age, thickness, and existing damage levels help determine suitability. Professional evaluation quickly identifies whether lifting represents the optimal solution for your specific circumstances.
