Foundation Crack Repair in Salt Lake City, UT
Basement wall crack repair in Salt Lake City with epoxy and polyurethane injection, sealing cracks that caulk can't fix. Free estimates.
Serving Salt Lake City and nearby communities.
Surface caulk doesn't hold up against ongoing soil pressure, which is why a crack that's been caulked once tends to reopen within a season or two. Salt Lake City Foundation Experts repairs foundation and basement wall cracks with epoxy or polyurethane injection, sealing the crack through the full thickness of the wall instead of just the surface.
Diagonal cracks above basement windows and stair-step cracks in brick are two patterns we see often in Salt Lake City's older masonry foundations, usually tied to settlement or freeze-thaw cycling widening a hairline crack over successive winters. We match the injection material to the crack type so the fix actually holds.

How our Foundation Crack Repair process works
Step 1Crack Inspection
Each crack is examined to determine type, width, and cause.
Step 2Surface Cleaning
Debris and loose material are removed from the crack area.
Step 3Injection Port Setup
Ports are installed along the crack to allow material injection.
Step 4Sealant Injection
Epoxy or polyurethane is injected to fill and bond the crack.
Step 5Surface Finishing
Excess material is removed and the surface is smoothed.
Step 6Final Inspection
The repair is checked to confirm a watertight and stable seal.
Materials
Materials and methods for Foundation Crack Repair
Which injection material we use depends on whether the crack is actively leaking or purely structural.

Epoxy Injection Resin
Bonds structural cracks rigidly, restoring strength in non-moving cracks common in settled foundations.

Polyurethane Foam Sealant
Expands to block active water infiltration, a better fit for cracks still seeping after snowmelt.

Injection Ports
Allow controlled, full-depth delivery of sealant rather than a surface-only patch.

Surface Primer
Prepares the concrete or masonry surface so the injected material bonds properly.

Masonry Patch Compound
Finishes and blends the repaired area into surrounding brick or block.

Protective Topcoat
Shields the repair from the same moisture exposure that caused the original crack.

DIY vs pro
DIY vs hiring a pro for Foundation Crack Repair
| DIY | Hire a pro |
|---|---|
| Monitoring a hairline crack's width over time with a pencil mark or gauge | Caulk sits on the surface and doesn't stop water pushed through under hydrostatic pressure the way full-depth injection does |
| Applying surface caulk as a temporary measure on a non-structural cosmetic crack | Widening cracks, stair-step patterns, or active seepage need injection that bonds through the wall thickness |
| — | Getting the material wrong, epoxy on an active leak or polyurethane on a structural crack, means redoing the repair |

Foundation Crack Repair FAQs
Why do I have diagonal cracks above my basement windows?
Diagonal cracks above windows usually form because the window opening is a weak point in the wall where settlement stress concentrates, common in older Salt Lake City foundations.
Can I just caulk a foundation crack myself or does it need injection?
Caulk only seals the surface and typically fails against ongoing hydrostatic pressure or settlement movement. Injection fills the crack through the full wall thickness, which is why it holds up longer.
What's the difference between epoxy and polyurethane injection?
Epoxy bonds rigidly and restores structural strength to a non-moving crack. Polyurethane expands and stays flexible, which makes it the better choice for actively leaking cracks.
How much does crack repair cost?
Most single-crack jobs run $400–$800, with multiple cracks typically falling in the $800–$2,000 range depending on count and accessibility.
Do I need a permit for crack injection?
Routine crack injection usually doesn't require a permit, but if the crack is tied to larger structural movement, the broader repair may need one.
How long does the repair take to cure?
Epoxy and polyurethane injections typically set within a few hours, and the area can usually be finished the same day.
