If you've ever looked at your driveway, sidewalk, or patio, you've seen the lines that divide concrete into sections. Those aren't decorative — they're expansion joints, and they serve a critical structural purpose.
Why Concrete Needs Joints
Concrete expands and contracts with temperature changes. Without joints, this movement causes random cracking. Expansion joints provide controlled gaps that allow concrete to move without cracking.
What Happens When Joints Fail
Over time, the original wood or foam filler in expansion joints rots, crumbles, and falls out. Empty joints cause several problems:
- Weeds grow in the gaps
- Water seeps under the concrete, causing soil erosion and settling
- Debris accumulates and becomes unsightly
- Tripping hazards develop
