Concrete is strong, but even the most durable slabs can settle, crack, or sink over time. Replacing an entire slab can be labor-intensive, disruptive, and time-consuming. Fortunately, concrete raising provides a practical alternative to restore uneven or sunken slabs without complete replacement. This article explores the most effective ways to form up concrete, highlighting techniques, benefits, and practical considerations for homeowners in Crystal Lake, IL, and nearby areas.
Concrete Raising: An Efficient Alternative to Replacement
Full concrete replacement involves demolition, debris removal, base preparation, and pouring new material, a process that is both disruptive and expensive. Concrete raising, sometimes called slabjacking, lifts and levels existing slabs by filling the void underneath. This method avoids demolition, reduces waste, and restores functionality quickly. It’s an ideal solution for driveways, patios, sidewalks, and other surfaces that have settled unevenly.
Effective Methods for Raising Concrete
Mudjacking (Traditional Slabjacking)
Mudjacking is a time-tested method for lifting and leveling concrete slabs.
- A slurry made from water, sand or soil, and cement is pumped under the slab through drilled holes.
- The mixture fills voids beneath the slab and lifts it to the desired level.
Advantages:
- Reliable for moderate lifts and widely available.
- Uses simple, readily available materials.
- Proven technique that has been used for decades.
Considerations:
- The slurry is heavy, which may cause some compression over time.
- Requires adequate cure time before the slab can be used fully.
- Occasionally, repeat leveling may be necessary as the material settles.
Polyurethane Foam Lifting (Polyjacking)
Polyurethane foam lifting is a modern approach that offers speed and durability.
- Small holes are drilled into the slab, and a two-part expanding foam is injected beneath it.
- The foam fills voids and lifts the slab, curing quickly for almost immediate use.
Advantages:
- Lightweight material reduces the risk of further settling.
- Quick curing allows minimal disruption to daily activities.
- Long-lasting and resistant to erosion, providing durable results.
Considerations:
- Requires specialized equipment and professional expertise.
- Minor settling may occur in certain soil conditions, although it is usually minimal.
Self-Leveling Compound (Surface-Level Adjustments)
When only minor dips or uneven spots need correction, self-leveling compounds are an effective option.
- A fluid cement-like mixture is poured over the surface to smooth imperfections.
- Ideal for interior floors, patios, or areas that don’t require significant lifting.
Advantages:
- Easy to work with and requires no heavy equipment.
- Quickly corrects minor unevenness without extensive preparation.
Considerations:
- Not suitable for lifting entire slabs.
- Requires a stable base to prevent cracking or future settling.
Comparing Methods for Concrete Raising
| Method | Best Use Case | Cure / Usable Time | Longevity / Durability |
| Mudjacking | Moderate lifts, traditional surfaces | Hours to a day | Durable, may settle over time |
| Polyurethane Foam (Polyjack) | High-traffic or unstable soil slabs | Minutes to an hour | Long-lasting, resistant to erosion |
| Self-Leveling Compound | Minor dips or surface leveling | Several hours | Moderate, best for surface corrections |
Practical Tips for a Successful Project
- Hire experienced contractors: Even affordable methods require skill for proper execution.
- Address underlying soil issues: Proper drainage and soil stabilization prevent future settling.
- Repair only necessary areas: Focus on the slabs that need attention to save time and effort.
- Schedule strategically: Timing your project can reduce inconvenience, especially for high-traffic areas.
When Foam Lifting Is Worth Considering
Polyurethane foam lifting is particularly beneficial when:
- Minimal disruption is required for driveways, patios, or sidewalks.
- The soil beneath the slab is unstable and cannot support heavy material.
- High-traffic or structural slabs need a durable and long-lasting solution.
- Quick completion is necessary with minimal downtime.
Potential Risks and Considerations
Even with concrete raising, certain risks should be considered:
- Incorrect injection: Poor technique can damage slabs or leave voids.
- Soil instability: Simply lifting the slab without addressing soil problems may result in future settlement.
- Surface finish: Holes drilled for raising must be patched carefully to maintain appearance.
- Choosing unqualified contractors: Experience matters; extremely low-cost options may compromise quality.
