Commercial catch basin repair addresses failed pavement and drainage at an inlet, such as a settled frame, broken collar, deteriorated structure or a low area that no longer directs runoff correctly. The visible depression is a symptom; the scope must identify whether the frame, structure, pipe connection, surrounding base or finished grade is failing.
What determines the scope
A repair can range from resetting the frame and reconstructing the collar to replacing damaged structure and adjacent pavement. Standing water away from the inlet may require broader grading or drainage design rather than a basin-only repair.
What a commercial proposal should define
- Inspect frame, grate, masonry or precast structure and pipe connections.
- Map settlement and cracking around the inlet.
- Confirm the intended finished grade and drainage path.
- Define excavation, base restoration and pavement tie-in.
- Keep sediment and demolition debris out of the storm system.
How to compare bids
Compare the same repair boundaries, depths, materials, preparation, access plan and exclusions. A lower number is not a comparable bid when it assumes a thinner section, skips failed base, omits traffic control or leaves drainage and striping unresolved.

Trace the drainage failure before resetting the surface
Settlement around an inlet can involve the frame, collar, structure, pipe connection, supporting material or surrounding grade. The repair scope should identify which component is failing and how the finished pavement will drain.
Put these items in the written scope
- Inspect the frame, grate, structure and connections.
- Map settlement and recurring ponding.
- Confirm finished grade and runoff direction.
- Define excavation, support and pavement tie-in.
- Keep demolition debris out of the storm system.

When settlement points below the surface
A sinking inlet or recurring void may need investigation beyond a surface patch. Review collapsed parking-lot drain symptoms and repair planning before defining excavation limits. Keep vehicles away from suspect unsupported pavement and include the location, access constraints and observed settlement in the site-review request.
Frequently Asked Questions
What should be included in a Commercial Catch Basin and Storm Drain Repair proposal?
The proposal should define repair limits, depth and material assumptions, preparation, traffic control, access, schedule conditions, exclusions and any connected drainage, concrete or striping work.
Can the work be completed while the property stays open?
Often it can be phased, but the workable plan depends on entrances, fire and accessible routes, deliveries, parking demand, cure or cooling time and the amount of safe staging space.
How do we know whether repair or replacement is appropriate?
The decision starts with the failure pattern and supporting conditions. Isolated sound areas may be preserved, while widespread movement, unstable base or drainage failure can require deeper correction.
