Know When to Cut Your Losses

In St. George's climate, concrete takes a beating. Temperatures swing from 105°F summers to freezing winters. UV breaks down surface sealers. Expansive soils shift. The result: cracking, heaving, and spalling that makes patching a losing battle.

Patching buys time — sometimes years, sometimes months. Replacement buys decades. When cracks are wide, sections have displaced vertically, or the surface is flaking away, you're patching a structural problem with a cosmetic fix.

We'll give you an honest read on your concrete. If repair makes sense, we'll tell you. If it doesn't, we'll show you why and give you a firm price to do it right.

New concrete poured after demolition by Sanchez Concrete in Southern Utah
New Concrete.
Done Once. Done Right.

When old concrete is hauled off and we start from scratch, we fix what caused the failure in the first place — poor subgrade, no control joints, undersized reinforcement. The replacement lasts because we address the root cause, not just the surface.

Replace or Repair?

The honest answer depends on the severity, age, and cause of the damage. Use this guide as a starting point — then call us for a free on-site assessment. We'll tell you straight.

Replace
Cracks wider than a quarter-inchWater infiltrates, rebar rusts, slab continues to move. Patching won't stop the cycle.
Replace
Heaved or sunken sectionsTrip hazard and drainage problem. The subgrade has shifted — surface patching won't fix the cause.
Replace
Widespread surface spallingWhen more than a quarter of the surface is flaking off, the concrete has reached the end of its service life.
Repair
Hairline cracks with no displacementControl-joint cracks that haven't opened wide and haven't caused any vertical movement can often be sealed and left alone.
Repair
Small isolated chips or edge damageMinor corner breaks or small surface chips on otherwise sound concrete are good candidates for a quality repair patch.

Concrete Replacement FAQs

Demo and haul-off typically runs $2–$5 per square foot depending on thickness and access. The replacement pour adds $6–$12 per square foot. Total all-in cost for a standard 400 sq ft driveway replacement is roughly $3,200–$6,800. Call 801-640-1788 for a free on-site estimate.
Repair makes sense for hairline cracks under 1/4 inch wide with no vertical displacement. Replace when cracks are wide, sections have heaved or sunk, the surface is spalling badly, or the slab is more than 30 years old. In St. George's climate, heat and UV break down patch materials fast — patching a fundamentally failing slab is usually throwing money away.
Yes — demolition, removal, and haul-off are included in every replacement job we do. We don't leave rubble for you to deal with. The site is cleared and graded before the new pour.
Most residential replacements — a driveway, patio, or sidewalk — are demoed one day and poured the next, or sometimes completed in a single day for smaller jobs. You can walk on the new concrete in 24–48 hours and drive on it in 7 days. Full strength at 28 days.
The main culprits in Southern Utah are thermal cycling (100°F+ summers, freezing winters), poor subgrade preparation in the original pour, inadequate reinforcement, and tree roots. Concrete placed without proper base compaction or control joints will crack prematurely regardless of the mix quality.
We can match the finish type — broom, exposed aggregate, smooth trowel — but new concrete will be lighter in color than aged concrete. The color difference typically evens out over 12–18 months of weathering. If you want the whole area to match, replacing the full section is cleaner than a partial replacement.
Beyond concrete replacement, we pour concrete driveways, patios, stamped concrete, RV pads, slabs & garage floors, and sidewalks & walkways across St. George and Washington County. Call 801-640-1788 for a free estimate.
