Signs of Failing Expansion Joints: What to Watch Out For
Expansion joints play a critical role in concrete health, but the effects can be serious when they start to fail. Knowing the signs of failing expansion joints helps you take early action before minor issues turn into major repairs.
At WMG Caulking, we specialize in sealing and repairing joints for residential and commercial properties in Omaha, NE, and the surrounding areas. Let’s explore the warning signs every property owner should know.
Why Expansion Joints Fail
Even well-installed joints can wear down over time due to:
Constant temperature changes
Water penetration
UV exposure
Heavy traffic and load-bearing stress
That’s why regular inspection is key. Spotting the signs of failing expansion joints early can save your entire concrete structure.
Common Signs of Failing Expansion Joints
1. Cracked or Missing Sealant
If the sealant is brittle, pulling away, or completely missing, it no longer protects the joint from:
Water infiltration
Chemical exposure
Dirt and plant growth
Cracked sealant is one of the first signs of failing expansion joints you’ll likely notice.
2. Weeds or Grass Growing in Joints
Vegetation growth inside joints indicates that the joint has lost its seal. This looks unsightly and allows roots to damage the surrounding concrete further.
3. Water Pooling or Seeping In
Puddles near joints or visible moisture in the seams are a red flag. Unsealed joints absorb water, which leads to base erosion and freeze-thaw damage.
4. Cracks Radiating From Joint Lines
If you notice surface cracks forming along or near expansion joints, it’s a clear sign of stress. The joint is no longer absorbing movement properly.
What to Do If You Notice These Signs
Don’t ignore the signs of failing expansion joints—they worsen with time. If you see any of these issues:
Avoid washing the area with high pressure
Remove visible debris or vegetation
Contact a professional to evaluate and reseal the joint
At WMG Caulking, we assess the joint’s condition and provide long-lasting repair solutions.
