Foundation Crack Repair: Stop Leaks, Restore Structure
We repair foundation cracks with epoxy and polyurethane injection. Stop water intrusion and restore structural integrity. Used alongside piering for complete foundation repair. Serving Tampa, Orlando & Central Florida.
Types of Foundation Cracks
Not all cracks are equal. Understanding the type helps us choose the right repair.
Vertical
Often caused by settling or shrinkage. Common in new construction. May be cosmetic if stable.
Horizontal
More serious. Can indicate hydrostatic pressure (water pushing against the wall). Common in Florida basements.
Diagonal
Often caused by differential settlement—one part of the foundation settling more than another.
Stair-step
In block or brick foundations. Follows mortar joints. Can indicate serious settling.
Which Cracks Are Serious vs Cosmetic?
We help you understand what needs attention.
Serious (needs inspection):
- • Cracks that are widening over time
- • Cracks that leak water
- • Horizontal or stair-step cracks
- • Cracks with sticking doors or uneven floors
- • Cracks wider than 1/8 inch
Often cosmetic:
- • Hairline vertical cracks (under 1/16 inch)
- • Cracks that haven't changed in years
- • No other signs of foundation issues
- • Shrinkage cracks in new construction
When in doubt, get a free inspection. We'll tell you honestly what needs repair.
Epoxy vs Polyurethane Injection
We use the right method for each crack type.
Epoxy Injection
- Structural repair—restores strength
- Best for non-leaking cracks
- Bonds crack faces together
- Permanent structural solution
Polyurethane Injection
- Waterproofing—stops leaks
- Best for leaking cracks
- Flexible—fills cracks even when wet
- Expands to seal voids
Why Crack Repair Alone Isn't Enough If Foundation Is Settling
Address the cause, not just the symptom.
If your foundation is actively settling, sealing cracks alone won't solve the problem. The foundation will continue to move, and new cracks will form—or the same cracks will reopen.
Our approach: We assess whether your foundation is settling during our free inspection. If it is, we recommend piering or push piers to stop the movement first. Then we repair the cracks. That's a complete, permanent solution.
If your foundation is stable and the cracks are from past settlement or shrinkage, crack injection alone may be sufficient. We'll tell you honestly.
Waterproofing Benefits of Crack Injection
Crack injection doesn't just repair structure—it stops water.
Leaking foundation cracks lead to moisture, mold, and musty basements. Polyurethane injection seals the crack from the inside, creating a watertight barrier. Even when the crack is actively leaking, polyurethane can be injected—it cures in the presence of water.
Combined with proper waterproofing and drainage, crack injection helps keep your basement dry and your foundation healthy.

Frequently Asked Questions
When should I repair foundation cracks?
Cracks that are widening, leaking, or accompanied by other signs (sticking doors, uneven floors) should be assessed immediately. Hairline cracks may be cosmetic. Schedule a free inspection for an honest evaluation.
What causes foundation cracks?
Settlement, soil movement, hydrostatic pressure, Florida's wet/dry cycles, and temperature changes can cause cracks. We diagnose the cause and recommend the right repair—often crack injection alongside piering if the foundation is still settling.
How long does crack repair last?
Quality crack repair is permanent when the underlying cause is addressed. If your foundation is still settling, we repair the settlement first (with piers), then seal the cracks. We use industry-leading materials and back our work with warranties.
Why isn't crack repair alone enough if my foundation is settling?
Sealing cracks addresses the symptom, not the cause. If the foundation continues to settle, cracks will reappear. We assess whether your foundation is actively settling during our free inspection. If it is, piering stops the movement, then we repair the cracks for a complete solution.
