Culvert Settling or Failing? Restore It Without Full Replacement
If your culvert is sinking, separating, or causing uneven ground above… you don’t need a full replacement.
At Greenstar Insulation, we lift and stabilize culverts quickly and cleanly—restoring proper support and preventing further damage without excavation or major downtime.
Why Culverts Settle or Fail
Culverts are critical for drainage, but over time, the soil around and beneath them can shift or wash away.
In the Shreveport and Bossier City area, heavy rain and soil movement are the biggest causes.
Here’s what typically leads to culvert problems:
- Soil erosion from water flow
- Poor compaction during installation
- Voids forming under or around the culvert
- Heavy loads from traffic above
- Long-term washout from improper drainage
As support weakens, the culvert can settle, shift, or even collapse.
Common Signs You Need Culvert Repair
- Sinkholes or depressions forming above the culvert
- Uneven pavement or ground above the structure
- Cracks in concrete or surrounding surfaces
- Water not flowing properly through the culvert
- Visible separation or misalignment
- Soft or unstable ground around the area
If you notice these issues, it’s important to act quickly before the damage spreads.
You may also have other structural areas settling, like parking lots, loading docks, or warehouse floors. We can stabilize multiple areas during the same project to save time and cost.
