Catch basins are essential to Pittsburgh’s stormwater drainage system, especially in neighborhoods like Squirrel Hill, Greenfield, and Shadyside, where old infrastructure meets steep, hilly terrain. When they fail, pooling water and pavement damage can follow—fast.
That’s why catch basin repair is a critical service that protects your asphalt, your safety, and the city’s water system. At Brant’s Asphalt, we’ve repaired hundreds of catch basins across Allegheny County, from high-traffic commercial lots in the Strip District to residential driveways in Mount Lebanon.
Whether your basin has collapsed from years of freeze-thaw cycles or simply needs resealing, here’s exactly how the repair process works—step by step.
Key Takeaways
- A damaged catch basin in Pittsburgh often shows signs like pooling water, cracked pavement, or sinking around grates.
- The repair process involves removing pavement, clearing debris, and rebuilding the basin using long-lasting materials suited for local weather.
- A new grate is installed, then the area is compacted and repaved so drainage works correctly and stays reliable.
- Ongoing issues may point to sewer system clogs, poor grading, weak materials, or debris buildup that needs professional help.
Step 1: Inspection and Diagnosis of Catch Basin Failure
Our first step is always a full visual inspection. In Pittsburgh, this often reveals issues caused by shifting soils, freeze-thaw damage, or clogged pipes from the heavy leaf fall in areas like Highland Park and Edgewood.
We check for signs like collapsed grates, pooling water, cracking pavement around the basin, and sinking or shifting blocks.
If needed, we also use camera scopes to assess internal pipe integrity—especially important for older systems tied into Pittsburgh’s combined sewer infrastructure.
Step 2: Cutting and Removal of the Surrounding Asphalt or Concrete
Once we confirm the basin needs repair, we cut and remove the surrounding asphalt or concrete surface. This requires precision.
We use diamond-blade saws to create clean edges and minimize disruption, especially in tightly packed areas like the South Side Flats, where parking and access are tight. The removal process clears the way for excavation without damaging adjacent pavement or curbs.
Step 3: Excavation and Debris Removal Around the Basin
Next, we dig down around the catch basin structure.
In Pittsburgh, older basins often sit deeper than modern code due to outdated stormwater layouts. We carefully remove old brick, block, or precast units, along with built-up debris—everything from silt and salt residue to broken glass and leaves.
This step is vital to prevent recurring drainage problems, particularly in flood-prone zones like Banksville and East Liberty.
Step 4: Rebuilding or Adjusting the Catch Basin Structure
Once exposed, we assess whether the basin requires a partial rebuild or a complete replacement.
In many cases, basins in older neighborhoods like Lawrenceville were built decades ago with brick and mortar, which don’t hold up well against our region’s freeze-thaw cycles. We rebuild with reinforced concrete or precast structures that meet Allegheny County Public Works standards, adjusting the elevation as needed to ensure proper drainage pitch.
Step 5: Installing a New Frame and Grate
With the structure sound, we install a new steel frame and heavy-duty grate.
These must match the traffic load—light-duty for private lots in Point Breeze, heavy-duty for commercial loading areas in East Pittsburgh. We secure them to the structure using concrete collars to prevent movement or rattling under vehicle traffic.
In high-traffic zones, we may weld the grate into place for added stability and theft prevention.
Step 6: Backfilling and Compacting the Area
We backfill the excavated area with crushed limestone or clean fill, depending on the base depth and soil conditions. Compaction is key here. Loose fill leads to settlement, especially in Pittsburgh’s variable clay soils.
We use vibratory plate compactors or jumping jacks to ensure the sub-base is stable enough to support new pavement. This prevents future sinkholes or cracking around the basin.
Step 7: Re-Paving With Asphalt or Concrete
The final step is repaving the surface. In most cases, we use hot-mix asphalt to match the surrounding lot or street.
In some commercial lots—like those near the Waterfront or Station Square—we may pour concrete for added durability and to blend with existing surfaces.
We feather and level the new surface so water flows properly into the basin, solving the original drainage issue for good.
What to Do if Your Catch Basin Problem Seems Incomplete
Sometimes, you can see a problem—like surface flooding or sinking asphalt—but aren’t sure if the issue is fully addressed. If you suspect something’s missing in the process, here are the steps we recommend taking.
Check if the Catch Basin Is Tied Into Pittsburgh’s Combined Sewer System
Many basins in older Pittsburgh neighborhoods feed into the combined sewer system maintained by ALCOSAN (Allegheny County Sanitary Authority).
If you’re still seeing pooling or backups after a repair, the basin may be clogged deeper in the system. We can coordinate with the Pittsburgh Water and Sewer Authority (PWSA) or recommend a licensed plumber for further investigation.
Inspect the Surrounding Pavement for Secondary Drainage Issues
Sometimes what looks like a catch basin failure is actually caused by poor grading or broken curbs. In places like Brookline or Beechview, older lots often lack proper water flow toward the basin.
We assess slope and paving condition to rule out—or correct—surface-level issues that may not have been addressed during a basic repair.
Confirm That Proper Materials Were Used for Your Basin
Not all repairs are equal. We’ve seen patch jobs using incorrect grates or substandard concrete that fail within months.
If your repair didn’t include heavy-duty materials rated for Pittsburgh’s climate and traffic loads, it could be a short-term fix. We can evaluate the workmanship and materials and provide a more permanent solution.
Look for Signs of Recurring Debris or Sediment Buildup
Even a brand-new catch basin can clog if it sits under heavy tree cover or in areas with poor street sweeping.
We see this often in parts of Oakland and Polish Hill. If you’re noticing recurring clogs, we may recommend periodic cleanouts or the installation of a debris trap to protect the basin from buildup.

Frequently Asked Questions
How long does a typical catch basin repair take in Pittsburgh?
Most repairs take one to two days, depending on basin depth, weather, and site conditions. We schedule efficiently to reduce disruption for residential driveways, commercial lots, or multi-unit properties.
Can catch basin repairs be completed during Pittsburgh’s winter season?
Winter repairs are possible with proper planning, but extreme cold can delay work. We monitor the weather closely and use cold-weather materials when needed for urgent repairs between November and March.
Are permits required for catch basin repairs on private commercial properties in Pittsburgh?
Permit needs vary by site. For repairs near sidewalks or storm connections, we coordinate with Pittsburgh’s Department of Mobility and Infrastructure to handle permitting and keep your project compliant.
Do you offer maintenance plans for properties with multiple catch basins?
Yes, we offer custom maintenance plans for properties with several basins. Regular inspections help prevent flooding, extend pavement life, and avoid emergency repairs, especially for retail centers and apartment complexes.
