Street Creep: What It Is, How It Damages Your Home, and What to Do About It
Street creep can damage your driveway and foundation by shifting concrete slabs. Learn the warning signs, why a cracked driveway may be serious, and how to protect your home with expert repairs.
What Is Street Creep?
If you’ve noticed cracks in your driveway, gaps between your garage floor and driveway, or pressure against your foundation walls, you may be dealing with a problem called street creep. Street creep happens when the concrete slabs that make up streets and driveways expand and contract during seasonal temperature changes. Over time, this movement pushes against your driveway and eventually your foundation. The result? Cracked driveways, damaged garage slabs, and stressed foundation walls. We know how overwhelming it feels to see cracks forming in your property but with the right guidance, the problem can be fixed before it causes major structural damage.
How Street Creep Works
Concrete naturally expands in the heat and contracts in the cold. While small movements are normal, problems arise when expansion joints (the designed gaps between slabs) can’t handle the movement.
In summer, hot temperatures cause street slabs to expand.
In winter, the slabs contract, leaving larger gaps.
Over time, debris fills these joints, preventing full contraction.
Each new expansion cycle pushes the slabs—and your driveway—closer to your home.
That pressure eventually impacts your garage floor and foundation walls. According to the American Concrete Institute, uncontrolled slab movement is one of the most common causes of cracking and structural stress in residential foundations (ACI).
Warning Signs of Street Creep
How do you know if street creep is affecting your home? Look for these signs:
Cracks forming in your driveway near the street or garage
Gaps or uneven transitions where the driveway meets the garage slab
Damage to foundation walls (bowing, stair-step cracks, or horizontal cracks)
Doors or windows in the garage that stick or won’t close properly
Expansion joints in the street or driveway filled with dirt, gravel, or debris
Is Having a Cracked Driveway Bad?
Not all cracked driveways mean you’re facing street creep—but some cracks do point to bigger issues.
Cosmetic Cracks: Hairline cracks from surface wear may not be urgent but should still be monitored.
Structural Cracks: Wide cracks, especially those accompanied by shifting slabs or gaps near the garage, often signal underlying movement from street creep.
A cracked driveway might not seem like a big deal at first, but if it’s connected to street creep, it’s a warning sign your foundation could be at risk.
How Street Creep Damages Your Foundation
Left unaddressed, street creep can lead to:
Garage Floor Damage: Pressure causes slabs to crack and shift.
Foundation Wall Stress: Expanding slabs push against basement or crawl space walls, causing cracks or inward bowing.
Water Intrusion: Cracks allow water to enter, increasing the risk of leaks and mold.
Costly Repairs: The longer street creep is ignored, the more extensive the damage becomes.
The University of Minnesota Extension notes that soil expansion, contraction, and slab pressure are major contributors to foundation wall damage in cold climates.

4. Waterproofing & Drainage
Seal cracks and install drainage systems to keep water out.
DIY vs. Professional Repair
You might be tempted to patch cracks in your driveway or fill expansion joints yourself. While this can temporarily hide cosmetic issues, it doesn’t address the real problem. Professional repair ensures:
Correct identification of street creep vs. normal cracking
Long-term protection with reinforced materials
Warranty-backed solutions for peace of mind
What Happens If You Ignore Street Creep?
Street creep is progressive—it doesn’t stop on its own. Ignoring it often leads to:
Worsening cracks in driveways and slabs
Costly foundation wall repairs
Water damage and mold problems in basements
Safety hazards for vehicles and pedestrians
The longer you wait, the more invasive (and expensive) the fix becomes.
FAQs About Street Creep
Q: Can street creep happen in newer neighborhoods?
Yes—if expansion joints aren’t installed or maintained properly, even new concrete is vulnerable.
Q: Is street creep covered by insurance?
Most policies do not cover foundation damage caused by natural soil or slab movement.
Q: How do I know if my driveway cracks are serious?
If cracks are wide, uneven, or accompanied by shifting slabs or foundation cracks, it’s time for a professional inspection.
