Signs Your Concrete Is Sinking or Cracking
Learn to identify early warning signs of concrete problems before they become major issues.
Uneven or Sloped Surfaces
Walk across your concrete surfaces and feel for unevenness. Look for sections that have settled lower than adjacent areas, creating lips or steps between slabs. Use a level or simply roll a ball across the surface—it shouldn't veer unexpectedly.
Uneven concrete creates trip hazards and indicates soil settlement or erosion beneath the slab. The problem will worsen over time as water infiltration accelerates the underlying soil issues.
Water Pooling in New Areas
Concrete should be graded to drain water away. If you notice water pooling in areas that previously drained properly, the slab has likely shifted. Pay attention after rain to where water collects and how long it takes to drain.
Standing water accelerates concrete deterioration and indicates improper drainage. It can also find its way into your foundation or basement, creating much larger problems.
Cracks That Keep Growing
Some hairline cracks in concrete are normal and cosmetic. Concerning cracks are those that grow wider over time, have vertical displacement (one side higher than the other), or form patterns that suggest structural movement.
Growing cracks indicate ongoing movement or settlement. What starts as a minor crack can eventually lead to complete slab failure if the underlying cause isn't addressed.
Gaps Along Foundation or Walls
Check where concrete slabs meet your home's foundation, garage walls, or steps. Gaps that have developed indicate settlement. Also look for separation at control joints that appears wider than originally designed.
Gaps between concrete and your foundation allow water infiltration and can indicate differential settlement that may affect your home's structure, not just the slab.
Cracks in Corners or Joints
Corners of concrete slabs are vulnerable to cracking because there's less supporting material. Check where sidewalks meet driveways, corners of patios, and areas near downspouts or gutters where water concentration is highest.
Corner cracks often spread if not addressed. Water from downspouts erodes soil beneath corners quickly, and early intervention can prevent larger sections from failing.
Your Options: Repair vs. Replace
Some concrete issues can be repaired or stabilized depending on the severity of the damage, while other situations may require partial or full replacement. A professional inspection can help determine the most appropriate solution.
Understanding the condition of the concrete early helps homeowners make informed decisions before the damage spreads or creates larger structural concerns.
