Cost to Raise Concrete Patio in Construction
A concrete patio is one of the most durable and versatile outdoor spaces, but over time, it can start to sink or settle unevenly due to soil erosion, poor drainage, or improper installation. When this happens, many homeowners choose to raise their concrete patio instead of replacing it entirely. Raising concrete is a cost-effective solution that restores functionality, improves safety, and extends the life of the patio.
This article will break down the methods, costs, factors, and benefits of raising a concrete patio in construction.
Why Raise a Concrete Patio?
Over the years, patios may shift or sink for several reasons. Raising the patio helps solve problems such as:
- Uneven surfaces – Eliminates tripping hazards and unsafe walking areas.
- Drainage issues – Prevents water pooling near the foundation.
- Aesthetic improvements – Restores a level, attractive look.
- Cost savings – Much cheaper than demolishing and pouring a new patio.
- Extended lifespan – Increases the usability of the existing structure.
Methods of Raising a Concrete Patio
1. Mudjacking (Slabjacking)
- Involves pumping a mixture of water, soil, and cement under the slab.
- Raises the patio back to its original level.
- More affordable but heavier material may contribute to future settling.
2. Polyurethane Foam Injection
- Expands under the slab to lift it back into position.
- Lightweight, durable, and water-resistant.
- Slightly more expensive than mudjacking but longer-lasting.
3. Concrete Resurfacing (for minor issues)
- Involves applying a new layer of concrete on top of the patio.
- Does not technically “raise” the slab but can smooth out low areas.
- Best for small uneven spots.
Cost to Raise a Concrete Patio
The cost depends on the size of the patio, the severity of sinking, and the method used.
| Service Type | Average Cost per Sq. Ft. | Typical Total Cost |
|---|---|---|
| Mudjacking (Slabjacking) | $3 – $6 | $600 – $1,200 |
| Polyurethane Foam Injection | $5 – $12 | $800 – $2,500 |
| Concrete Resurfacing | $3 – $7 | $500 – $1,500 |
On average, raising a concrete patio costs between $800 and $2,500, depending on the method chosen.
Factors That Affect the Cost
- Patio Size – Larger patios require more material and labor.
- Level of Sinking – Deeper settlement requires more fill and time.
- Soil Conditions – Poor soil stability may increase complexity.
- Accessibility – Hard-to-reach patios may require special equipment.
- Chosen Method – Foam injection is more expensive but offers long-term results compared to mudjacking.
Benefits of Raising Instead of Replacing
- Cost-effective – Raising is often 50–70% cheaper than replacement.
- Faster process – Most patios can be lifted in just a few hours.
- Minimal disruption – No need for demolition or new concrete curing time.
- Environmentally friendly – Saves waste from demolishing old slabs.
When to Replace Instead of Raise
In some cases, replacement may be a better option, such as when:
- The patio has large cracks or crumbling edges.
- The concrete is severely deteriorated.
- The slab has sunk beyond repairable levels.
Conclusion
The cost to raise a concrete patio in construction typically ranges from $800 to $2,500, making it a practical solution for homeowners facing sinking or uneven patios. Choosing between mudjacking, foam injection, or resurfacing depends on budget, longevity, and severity of the issue. Raising a patio is not only affordable but also extends the life of the concrete while improving safety and aesthetics.
FAQs About Raising Concrete Patios
Q1. How long does it take to raise a concrete patio?
Most patios can be raised in 2–4 hours, and the area is usable within the same day.
Q2. Which is better: mudjacking or foam injection?
Foam injection is more durable, lightweight, and water-resistant, while mudjacking is more affordable but heavier.
Q3. Can all patios be raised?
Most patios can be raised, but if the concrete is severely cracked or deteriorated, replacement may be necessary.
Q4. How long does a raised patio last?
With proper soil stability and drainage, a raised patio can last 10–20 years or longer.
Q5. Is raising a patio cheaper than replacing it?
Yes, raising a patio is typically 50–70% cheaper than full replacement.
Q6. Does raising concrete fix drainage issues?
Yes, lifting the patio helps restore proper slope and prevents water pooling.
Q7. Will the repair be noticeable?
In most cases, the drilled holes for mudjacking or foam injection are small and can be filled to blend with the patio surface.
