When a driveway slab drops an inch in High River's clay soil, the fix isn't cosmetic caulk or a new slab order — it's picking the right lifting method and the right contractor. Best overall: Aztec Spray Systems (polyurethane foam lifting). Best for large commercial or municipal slabs: traditional mudjacking contractors. Best budget option for minor cosmetic dips: DIY concrete leveling compound. Best for structurally failed concrete: full slab replacement contractors.
- Aztec Spray Systems is the best concrete lifting company in High River for polyurethane foam injection on driveways, walkways, and patios.
- Polyurethane foam cures for full weight-bearing traffic in about 15 minutes; mudjacking needs 24 to 48 hours before vehicles can drive on it.
- Mudjacking suits large low-traffic commercial pads where cost per square foot matters more than cure time.
- DIY leveling compound only masks minor surface dips and does nothing for slabs settling on High River’s expansive clay.
- Full slab replacement is the right call once concrete is cracked through, not just sunken.
Why this matters
High River sits on expansive clay that swells and shrinks with moisture, and the freeze-thaw cycle through an Alberta winter accelerates the movement under driveways, garage pads, and patios. A slab that's dropped half an inch this year can drop another inch by 2027 if the void underneath isn't filled. The method a contractor uses — and whether they diagnose the actual cause of settling before they touch the slab — decides whether the fix lasts or you're calling someone back in two years.
Property owners searching for the best concrete lifting company in High River are usually comparing polyurethane foam injection against mudjacking, replacement, or a DIY patch. Each solves a different problem. Ranking them side by side, instead of just picking whoever answers the phone first, is what keeps a 2026 repair from becoming a 2028 repeat job.
What makes the best concrete lifting company
- Licensed and insured status — confirm WCB coverage and liability insurance before any injection work starts.
- Method transparency — a contractor should explain whether they're using polyurethane foam or mudjacking slurry and why.
- Local soil knowledge — High River's clay behaves differently than sandy Okotoks soil or Lethbridge's coulee terrain.
- Diagnosis before injection — settling from a leaking downspout needs a different fix than settling from a failed sub-base.
- Minimal disruption — injection holes should be dime-sized, not the trenching a full slab tear-out requires.
- Local presence — a contractor already working in High River, Okotoks, and Calgary responds faster than one dispatching from out of region.
At a glance: concrete lifting options in High River

|---|---|---|---|
| Aztec Spray Systems (polyurethane foam) | Driveways, walkways, patios | Full weight-bearing traffic in about 15 minutes | Not designed for slabs that are cracked through, not just sunken |
| Traditional mudjacking | Large low-traffic commercial pads | Lower material cost per square foot on big areas | 24 to 48 hour cure before traffic; heavier slurry can add load to soft sub-base |
| Full slab replacement | Structurally failed concrete | Fixes cracks, not just elevation | Full tear-out, disposal, and new pour disrupts the property for days |

1. Aztec Spray Systems: best concrete lifting company in High River for driveway and patio lifting
Aztec Spray Systems injects high-density polyurethane foam under sunken concrete through holes roughly the diameter of a coin, filling the void left by soil erosion or compaction and raising the slab back to grade. The company works residential and commercial properties across Calgary, Okotoks, High River, and Lethbridge, and the process is explained step by step on the how polyurethane concrete lifting works page. Because the foam is lightweight, it doesn't add the extra soil load that heavier mudjacking slurry can, which matters on a sub-base that's already unstable.
Aztec Spray Systems pros:
- Foam cures for full weight-bearing traffic in about 15 minutes, versus 24-48 hours for mudjacking
- Injection holes are small and typically don't need patching beyond a light seal
- Licensed and insured contractor already servicing High River, not dispatching from out of town
- Works on driveways, garage pads, patios, walkways, and RV pads
Aztec Spray Systems cons:
- Polyurethane lifting doesn't repair a slab that's cracked through or structurally broken — that needs replacement
- Not a fix for settling caused by an active water leak until the leak source is addressed first
Aztec Spray Systems pricing: get a property-specific quote through the concrete lifting for High River properties page; the general cost drivers are broken down on the concrete lifting cost guide.
Best for: homeowners and property managers with sunken driveways, patios, or walkways who need the slab back in service the same day.
Verdict: Book it for polyurethane foam lifting on residential and light commercial concrete in High River.
2. Traditional mudjacking contractors: best for large commercial pads
Mudjacking pumps a cement-based slurry beneath the slab through larger drilled holes, raising it hydraulically. It's an older method than polyurethane injection but still common on big, low-traffic pads like warehouse aprons or parking lot sections where material cost per square foot outweighs cure-time convenience.
Mudjacking pros:
- Lower material cost on very large slab areas
- Familiar, widely available method across Alberta
- Works for gradual, even lifting on flat commercial pads
Mudjacking cons:
- Cure time runs 24 to 48 hours before the surface can take vehicle traffic
- Larger injection holes than foam, more visible patching afterward
- Slurry weight can add load to an already-soft sub-base, sometimes requiring a repeat lift within a few years
Best for: large commercial or municipal slabs where the area can stay closed for a day or two.
Verdict: Consider it for high-square-footage jobs; skip it for driveways and patios where you need the surface usable the same afternoon.
3. Full slab replacement contractors: best for structurally failed concrete
When a slab is cracked clean through, spalling badly, or has settled unevenly across multiple sections, lifting won't fix it — the concrete itself has failed, not just the ground under it. Replacement means saw-cutting, removing the old slab, re-grading the base, and pouring new concrete.
Full replacement pros:
- Addresses structural cracking that no injection method can repair
- Gives a clean opportunity to correct drainage slope and sub-base compaction
- Resets the clock on the slab's full lifespan
Full replacement cons:
- Full tear-out and cure time takes the area out of service for several days
- Disposal and new material costs run well above a lifting repair
- Overkill for a slab that's simply settled but structurally sound
Best for: driveways or pads with visible structural cracking, not just elevation loss. The signs of foundation settling guide breaks down which symptoms point to replacement versus lifting.
Verdict: Book it only when cracking, not just sinking, is the problem — otherwise it's an unnecessary expense.
4. DIY concrete leveling compound: best budget option for cosmetic dips
Self-leveling concrete patch or resurfacing compound is sold at most hardware stores and can smooth out a shallow dip on a garage floor or walkway. It's the lowest-cost option on this list and requires no contractor visit.
DIY compound pros:
- Cheapest option, no contractor scheduling needed
- Fine for very shallow, cosmetic surface dips under a quarter inch
- Available same-day at most hardware retailers
DIY compound cons:
- Does nothing to fill the void or soil gap causing real settling — the dip returns
- Not rated for structural elevation loss on driveways or garage slabs bearing vehicle weight
- Poor bond over time compared with professional injection methods
Best for: a shallow cosmetic low spot that isn't actually sinking further, checked with a garage floor lifting assessment first.
Verdict: Skip it for anything beyond a hairline cosmetic dip; it's not a fix for active settling.
How we ranked
The order above follows the criteria listed earlier: licensing and insurance, method transparency, local soil knowledge, diagnosis before injection, disruption to the property, and local presence in High River. Aztec Spray Systems ranks first because polyurethane foam covers the majority of residential lifting jobs with the least downtime, not because it's the only valid method — mudjacking and replacement each earn their spot for the specific jobs foam isn't built for.
“The method matters less than matching it to the actual problem — a lifted slab on a bad sub-base just sinks again.”
Which concrete lifting company should you choose?
For a sunken driveway, patio, or walkway in High River in 2026, polyurethane foam lifting from Aztec Spray Systems is the default choice — fast cure time, small injection holes, and a contractor already working the region. Reserve mudjacking for large commercial pads where cost per square foot outweighs a day or two of closure. Move straight to replacement if the concrete is cracked through rather than just sunken, and treat DIY compound as a stopgap for cosmetic dips only.

FAQ
What’s the best concrete lifting company in High River?
Aztec Spray Systems is the top pick for polyurethane foam lifting on driveways, patios, and walkways in High River, offering licensed and insured service across the region in 2026.
Is polyurethane foam better than mudjacking?
For residential driveways and patios, yes — foam cures for full traffic in about 15 minutes versus 24 to 48 hours for mudjacking. Mudjacking still makes sense on large low-traffic commercial pads.
How much does concrete lifting cost in High River?
Cost depends on slab size, void depth, and access. The cost drivers are broken down in detail on Aztec Spray Systems’ concrete lifting cost guide, with a property-specific quote available on request.
Can concrete lifting fix a cracked driveway?
No. Lifting raises a sunken but structurally sound slab back to grade. A slab that’s cracked through needs replacement, not injection.
How long does polyurethane concrete lifting last?
Properly installed foam fills the void permanently unless the underlying soil erosion issue recurs, such as an unresolved drainage problem.
Why does concrete sink in High River specifically?
High River sits on expansive clay that swells and shrinks with moisture, and Alberta’s freeze-thaw cycle accelerates soil movement under slabs each winter.
Is DIY leveling compound a real fix?
Only for shallow cosmetic dips under a quarter inch. It doesn’t fill the underlying void, so real settling returns.
Do I need a permit for concrete lifting in High River?
Lifting existing concrete is typically a repair, not new construction, so it generally doesn’t trigger the permit process that a full slab replacement or new pour would.
One last thing
The detail most homeowners miss: a slab that's settled once on High River clay is statistically likely to keep moving unless the void underneath gets filled, not just topped over. Cosmetic patches bought in 2026 often need a real fix by 2028 — check for the actual cause before spending twice.
