Repair First, When Repair Makes Sense
Concrete repair in Grand Junction starts with one question: is the slab worth keeping? Hairline cracks in a driveway, or a patio corner that dropped an inch, can often be fixed for far less than new concrete. A slab that has broken into pieces, flaked badly or is still on the move is another story. We look at the damage, track down the cause, and tell you plainly whether repair or replacement is the smarter spend. In this valley the cause is usually water: sprinklers, gutters or a leaking line wetting the soil under part of the slab.
Common problems and what we do about them
- Hairline and small cracks: cleaned and sealed with a flexible crack filler to keep water out of the base.
- Open control joints: caulked with a backer rod and joint sealant so water and weeds stay out.
- Sunken panels: an unbroken slab that has settled can often be lifted with mudjacking or foam leveling.
- Flaking or scaled surfaces: a sound slab with surface damage can be resurfaced with a thin cement-based overlay.
- Broken edges and spalls: patched with a repair mortar bonded to the old concrete.
- Trip edges on walks: lifted, ground down, or replaced panel by panel.
Fix it or replace it?
Our rule comes straight from HomeGuide. Its leveling guide says to replace rather than level when cracks are over a quarter inch wide, when spalling or surface damage is significant, or when the concrete is badly deteriorated. Its resurfacing guide adds that cracks wider than a quarter inch usually signal a deeper problem and come back through a new topping. HomeGuide also puts the life of a leveling job at 5 to 10 years or more, but only once the water causing the settlement has been dealt with; skip that step and the slab drops again.
Fixing the cause, not just the crack
The Colorado Geological Survey lists lawn and landscape irrigation, water trapped under slabs, and leaking water and sewer lines as the main ways moisture reaches the soil, and it notes that irrigation rarely wets the ground evenly. In a dry climate like Grand Junction's, with about nine inches of rain a year, the wet spots under a slab are almost always ones we create. So part of every repair visit is looking at sprinkler heads, drip lines, downspouts and grade around the damaged area. Redirecting a downspout or moving a spray head can be the most valuable part of the job.
Winter damage
Grand Junction's winter nights average in the teens while afternoons often thaw, so water in cracks and joints freezes and thaws many times a season. Each cycle pries the crack a little wider. Sealing cracks and joints in fall, before the first freeze around mid-October, keeps that water out. Using sand instead of de-icing salt on younger concrete, and keeping slabs sealed, slows surface scaling.

Concrete Repair Questions
Can a cracked driveway be repaired?
Small cracks can be sealed and a sound slab can be resurfaced. HomeGuide recommends replacement when cracks are wider than a quarter inch, with significant spalling, or when the concrete is badly deteriorated.
What is the difference between mudjacking and foam leveling?
Both lift a sunken slab by pumping material underneath. Mudjacking uses a cement-based slurry and costs about $4 to $9 per square foot; foam leveling uses expanding polyurethane at about $8 to $25, according to HomeGuide. Foam is lighter and often lasts longer.
Why does my concrete keep sinking?
Usually because water keeps reaching the soil under it from sprinklers, downspouts or a leak. Leveling without fixing the water source often leads to resettling, so we look at drainage on every repair.
Is resurfacing worth it?
For a slab that is sound underneath but worn or flaking on top, it usually is. HomeGuide lists resurfacing at $3 to $7 a square foot. Wide or active cracks will telegraph through a new surface, though, and then replacement is the better value.
When should I seal cracks?
Fall is ideal, before the first freeze around mid-October, so water cannot get in and freeze over the winter.
