Concrete Repair in Spokane, WA

Not every damaged slab needs to be torn out. All Phase Concrete repairs cracked, flaking and sunken concrete on driveways, patios, sidewalks, steps and garage floors across Spokane, Spokane Valley, Liberty Lake, Greenacres and Otis Orchards. We’ve been in residential concrete for over 25 years, and we’ll tell you straight whether a repair will last or whether replacement is the better use of your money.

Common concrete problems we fix

• Cracks. Hairline cracks are normal as concrete cures and shrinks. Wider cracks, cracks that keep growing, and cracks where one side sits higher than the other are signs the slab or the ground under it is moving. Sealing and filling cracks early keeps water out, and that keeps the damage from spreading.
• Spalling and surface flaking. In Spokane this is usually caused by freeze-thaw cycles and de-icing salt. Water soaks into the surface, freezes, expands and pops off small flakes until the stones underneath show through.
• Sunken or settled slabs. A section of sidewalk, patio or driveway has dropped below the slabs around it. This creates trip hazards and sends water toward your house instead of away from it.
• Heaving. Frost, tree roots or poor drainage push a section up.
• Crumbling steps and edges. Step edges and the ends of slabs take the most impact and break down first.

Repair options

Which repair is right depends on what’s wrong and what’s under the slab:

• Crack filling and sealing. For cracks over a sound base, filling and sealing keeps water and ice out.
• Resurfacing. When the slab is solid but the surface is worn, flaking or stained, a new surface layer can make it look new again, for far less than replacement.
• Slab leveling and lifting. Sunken sections can often be raised back to level instead of being replaced.
• Section replacement. When one panel is broken or badly settled and the rest is fine, we cut out and repour just that section. Our concrete cutting gives clean, straight edges so the new section fits tight.
• Full replacement. When the concrete is cracked throughout, heaving in several places, or the base has failed, patching only buys a little time. In that case we’ll recommend removal and a new pour.

How a repair job works

1. Free assessment. We look at the damage, check how the slab sits and drains, and figure out why it failed. Fixing the cause matters as much as fixing the crack.
2. Honest recommendation. We tell you whether repair or replacement makes more sense, and what each one costs.
3. Prep. We clean out cracks, grind or prep the surface, and cut out damaged areas as needed.
4. Repair. We fill, resurface, level or repour, depending on the plan.
5. Protect. We seal the repaired area where it makes sense, and tell you how to keep it in good shape through winter.

Repair or replace?

Repair is usually the better value when the damage is limited to one section or to the surface, and the ground underneath is solid. It can cost a few hundred dollars instead of several thousand. Replacement is the smarter long-term choice when the slab is broken up in many places or keeps moving because the base has failed. Our Spokane concrete cost guide compares the two in more detail.

Preventing future damage

• Fill and seal cracks as soon as they show up, before winter.
• Use sand instead of rock salt on your concrete.
• Keep gutters and downspouts draining away from slabs.
• Reseal driveways, patios and walkways every few years.
