Parking Lot Storm Sewer & Manhole Replacement
HT Strenger repairs and replaces storm sewer structures under commercial parking lots and drives across Lake County and greater Chicagoland. Property managers, HOA boards, retail landlords, industrial park owners, and municipalities call us when a catch basin has collapsed under a truck axle, a manhole cover is sitting three inches below grade, or a storm main has failed and the lot floods every heavy rain. We handle the excavation, the structure replacement, the pipe repair, and the asphalt or concrete patch, and we pull the permits your village requires.
We inspect the structure with the lid off, sound the pipe with a camera when the geometry allows, and give you a straight recommendation on repair versus replacement.

Why Storm Structures Fail
Parking lot storm sewers take a beating that homeowners never see. The common failure patterns:
Settlement around the structure. The pavement drops, the frame stays put, and now the lid sits proud of the surface and cracks the surrounding asphalt.
Frost heave and freeze-thaw cracking. Northern Illinois winters cycle above and below freezing dozens of times a season. Old brick catch basins and even mid-century precast structures crack, shift, and leak.
Truck axle loads. A catch basin frame that was fine for a 1980s-era Ford Econoline gives out under modern delivery trucks and fire apparatus.
Root intrusion. Storm laterals are almost never as tight as the plans suggest. Roots find the joints, then take over.
Sediment and grit buildup. Sump basins that were never cleaned fill with silt and stop catching water at the surface.
Manhole and Catch Basin Replacement
Full replacement usually means excavating the failed structure, cutting back to sound pipe, setting a new precast manhole or catch basin, resetting the frame and lid to the finished grade, backfilling with compacted stone, and restoring the surface. On busy commercial lots, we phase the work so the property stays open, and we barricade the excavation to the village’s traffic-control requirements. Where feasible we use rehab methods like manhole lining and grade adjustment rings instead of full replacement, and that saves the owner meaningful money on structures that are still fundamentally sound.
Pro Tip: Ask your snowplow contractor to mark the location of every catch basin and manhole on your lot before the first snowfall. Every winter we get calls to fix a frame or lid that got clipped by a plow blade because nobody flagged it. Cheap to prevent, expensive to fix.
Storm Main and Lateral Repair
When the pipe itself is the problem, we camera the run, cut back to sound pipe, replace the damaged section, and restore the trench. On longer runs we can trenchless-line the pipe from an existing structure and avoid tearing up more of your lot than necessary. Where the storm system ties into the village combined sewer, we coordinate with the local public works department for the tap and inspection.
