Serving South Salt Lake and nearby communities.

Stair-step cracks running along the mortar joints of an older block foundation are common across South Salt Lake's mid-century housing stock, and not every crack means the same thing. South Salt Lake Foundation Pros inspects each crack to tell the difference between cosmetic shrinkage and the kind of movement that needs structural attention.

Once we know what we're dealing with, we seal it with epoxy or polyurethane injection depending on whether the crack is dry or actively letting water through, restoring the bond and stopping moisture from working its way inside.

How it works

How Our Foundation Crack Repair Process Works

Step 1
Crack Inspection
Each crack is examined to determine type, width, and cause.
Step 2
Surface Cleaning
Debris and loose material are removed from the crack area.
Step 3
Injection Port Setup
Ports are installed along the crack to allow material injection.
Step 4
Sealant Injection
Epoxy or polyurethane is injected to fill and bond the crack.
Step 5
Surface Finishing
Excess material is removed and the surface is smoothed.
Step 6
Final Inspection
The repair is checked to confirm a watertight and stable seal.

Materials

Materials and Methods for Foundation Crack Repair

Not every crack takes the same material. Whether it's structural or just surface shrinkage decides the injection choice.

Epoxy Injection Resin
Bonds structural cracks for added strength and stability, the right call on cracks that aren't actively leaking.
Polyurethane Foam Sealant
Expands to fill cracks and block water infiltration, better suited to active water intrusion after snowmelt.
Injection Ports
Allow controlled delivery of sealant into the crack cavity along the full length of a stair-step crack.
Surface Primer
Prepares concrete surfaces for proper material adhesion before injection begins.
Masonry Patch Compound
Used to finish and blend repaired surface areas on block foundations common in older South Salt Lake homes.
Protective Topcoat
Applied to shield the repaired area from moisture exposure through future freeze-thaw cycles.

DIY vs pro

DIY vs Hiring a Pro for Foundation Crack Repair

DIY	Hire a pro
Hairline cracks under about 1/8 inch, no visible movement, and dry year-round can sometimes be sealed with hardware-store caulk as a temporary fix	Stair-step cracks, horizontal cracks, or any crack that's widened recently signal structural movement that caulk won't fix
Monitoring crack width with a pencil mark over several months to see if it's active	Active water intrusion through a crack needs polyurethane injection, not surface sealant, to actually stop the leak

FAQs

Foundation Crack Repair FAQs

How do I know if my foundation cracks are serious or just cosmetic?

Hairline cracks under 1/8 inch that stay the same width and don't leak are usually cosmetic. Stair-step patterns, horizontal cracks, or cracks that widen over time point to structural movement.

Is it normal for older Salt Lake homes to have stair-step cracks?

Stair-step cracking along mortar joints is common in older block foundations here, but the severity still needs an inspection to confirm whether it's cosmetic or active settlement.

Can I fill foundation cracks myself?

Hairline, dry, non-moving cracks can sometimes be sealed with a basic caulk as a stopgap. Active or widening cracks need professional epoxy or polyurethane injection to actually bond or seal properly.

What's the difference between epoxy and polyurethane crack injection?

Epoxy bonds and restores structural strength on dry cracks. Polyurethane expands and seals, making it the better choice for cracks with active water intrusion.

How much does foundation crack repair cost?

Most crack injections run a few hundred to a thousand dollars per crack depending on length and material, with multi-crack jobs priced accordingly. Call for a free estimate.

Do I need a permit to fix a foundation crack?

Standard interior crack injection usually doesn't require a permit. If the crack signals structural settlement needing piering, that follow-up work typically does.
