Catch Basins

Catch Basin Cleaning & Repair

Cleaning, repair and rebuild of parking lot catch basins across Greater Cincinnati, including the concrete around them, which is usually what has actually failed.

Drainage Structures

Drainage Decides How Long a Lot Lasts

Every parking area is built to move water to a handful of points and get it underground. When those points stop working, the water does not disappear. It spreads across the surface, sits at the low spots, and works its way under the pavement until the base gives up.

Affinity cleans catch basins out, rebuilds the ones that have deteriorated, and replaces the concrete around them. It is unglamorous work, and it is the difference between a lot that needs sections repaired and one that needs replacing.

What's Included

Catch Basin Cleaning & Repair

01

Cleaning & Debris Removal

Catch basins fill from the bottom up with sediment, gravel, leaves and trash until the outlet is choked and the basin stops taking water. Clearing them out is routine work that almost never gets scheduled until something backs up.

  • Sediment and debris cleared from the sump
  • Outlet and inlet checked for flow
  • Material removed from the property

02

Structure Repair & Rebuild

The block or brick throat of a basin deteriorates from the water passing through it. Once it starts collapsing, the frame loses support and the concrete around it follows. Affinity rebuilds the structure back to the frame.

  • Deteriorated block and mortar rebuilt
  • Throat re-formed to the correct depth
  • Structure brought back to bear the frame

03

Frames, Grates & Lids

A sunken or rocking grate is both a maintenance problem and a liability on a lot the public drives across. Frames get reset to the surrounding grade and secured so the casting sits solid under traffic.

  • Frames reset to the finished grade
  • Rocking and sunken castings corrected
  • Grates and lids seated properly

04

Concrete Around the Structure

The concrete collar surrounding a basin takes constant load and is usually the first thing to break up. Because Affinity is a concrete contractor, the drainage structure and the concrete around it get handled as one job.

  • Failed collar and surrounding slab replaced
  • Grade re-shaped so water reaches the inlet
  • One contractor for structure and concrete

For Property Managers

Put It on a Schedule Instead

Basins on a commercial lot are worth clearing before the wet season rather than after a tenant reports standing water. Affinity handles them as one-off calls or as part of total concrete and parking lot maintenance across the whole property.

  • Retail and office properties
  • Churches and schools
  • Apartment and condo properties
  • HOAs and facility managers

FAQ

Catch Basin Questions

How do I know a catch basin needs attention?
Water standing in the lot after rain is the usual sign, along with a grate that rocks or sits below the surrounding surface, and concrete breaking up in a ring around the structure. Any of the three means the basin is worth looking at.
Why hire a concrete contractor rather than a drain cleaner?
Clearing the sump is only half of it. What normally fails is the block throat, the frame seating and the concrete collar around the structure, all of which is masonry and concrete work. Handling both means one contractor rather than a drain service followed by a separate concrete repair.
What does cleaning a catch basin involve?
The sediment, gravel, leaves and trash that collect in the sump are cleared out and removed from the property, and the inlet and outlet are checked for flow so water can actually leave the structure.
Can this go on a schedule?
Yes. Basins on a commercial lot are worth clearing ahead of the wet season rather than after a tenant reports standing water, and Affinity handles them either as one-off calls or as part of total concrete and parking lot maintenance across the property.
