Concrete That Lasts: Patios, Driveways & Walkways : Pour Fresh or Resurface?
Excerpt: Should you resurface that cracked patio or tear it all out? From a contractor's perspective, here's how to decide — and why what's under the slab matters more than what's on top.
Concrete flatwork takes a beating across the Salt Lake Valley. Between freezing winter cycles and heavy summer sun, your patios, driveways, and walkways work harder than you think. Eventually, every homeowner faces the same question: do you patch over the wear and tear, or do you start over from scratch?
From a contractor's point of view, the right answer depends entirely on what is happening beneath the surface: especially given Utah's challenging clay soils.
This is Day 1 of our 3-part series, Concrete That Lasts, exploring how to protect your investment from the ground up.
When Resurfacing Is Viable
Resurfacing isn’t a structural fix: it’s a cosmetic reset. If your slab is fundamentally sound, a polymer-modified overlay (typically 1/4 to 1/2 inch thick) gives you a fresh surface without the expense of a full tear-out.
What to look for
Minor surface cracks: Hairline cracks that show no vertical displacement or movement.
Spalling and scaling: Surface pitting or flaking caused by de-icing salts or freeze-thaw cycles.
Uneven color or fading: Stains, discoloration, or worn-out decorative finishes.
Why it matters
Resurfacing saves upfront money: typically running 40% to 60% less than a complete replacement. It extends the life of a stable slab by 7 to 15 years. But remember: an overlay will only perform as well as the concrete underneath it. If the slab is moving, the overlay will fail right along with it.
When You Need a Full Tear-Out and Repour
If your concrete is failing structurally, slapping a thin layer over the top is throwing money away. Major damage requires complete removal, haul-away, and a proper repour.
What to look for
Major settling or uneven panels: Trip lips where one section has dropped or heaved significantly higher than the next.
Crumbling edges and deep cracks: Fissures wider than a quarter-inch that continue to grow or shift seasonally.
Drainage problems: Water pooling against your foundation or pooling on the driveway instead of sloping away.
Rebar corrosion: Rust stains bleeding through the concrete, indicating internal steel is expanding and breaking the slab apart.
Why it matters
Full-depth replacement lets you reset the clock entirely. It gives us the opportunity to adjust thickness, upgrade reinforcement, and fix the underlying subgrade: the most critical step for long-term durability.
The Subgrade Secret: Why General Contractors Matter in Utah
Here is what many homeowners overlook: concrete fails because of the dirt underneath it, not just the mix on top.
Salt Lake Valley sits on expansive clay soils that swell when wet and shrink when dry. Without proper excavation, compaction, and drainage management, even brand-new concrete will crack and shift within a few seasons.
As a full-service general contractor salt lake city homeowners trust, we don’t just pour concrete: we engineer the subbase. Proper grading, heavy-duty road base compaction, and strategic placement of control joints ensure your new flatwork handles seasonal ground movement without cracking apart.
