Oberlin is a small city of about 8,200 people in Lorain County, and most of its homes were built before 1960 - many as far back as the late 1800s. That means a lot of original wood framing, old foundations built to standards that no longer apply, and concrete flatwork that may have been installed decades ago with no engineered base beneath it. The city sees 40 to 50 inches of snow in a typical year, with freeze-thaw cycles that run from December through March. Each cycle drives water into cracks in driveways, steps, and sidewalks, freezes it, and widens those cracks a little more. Homes that have been through 50 or 100 of those cycles are showing it.

Lorain County clay soil is the other constant factor. Clay holds water against concrete and foundation walls long after rain or snowmelt, and it shrinks when dry - a cycle that puts pressure on everything above it. Flat terrain around Oberlin means drainage has nowhere natural to go, so how a driveway, patio, or foundation is sloped and basecoursed determines whether water moves away from the structure or pools against it. Properties with deferred maintenance - and Oberlin has many, given its high renter population and mix of converted multi-unit homes near the college - often have drainage problems that have been building up quietly for years.

Oberlin is a small city of about 8,200 people in Lorain County, about 35 miles southwest of Cleveland. Oberlin College - founded in 1833 - sits at the center of town and shapes much of the city's character and economy. The streets closest to campus are lined with Victorian, Queen Anne, and Craftsman-style homes built between roughly 1880 and 1930, and many have been converted to rental units over the decades. Tappan Square, the large tree-filled park between the college and downtown, is the most recognizable public space in the city and the landmark most residents use to orient themselves.

Oberlin sits on flat terrain surrounded by farmland, and the city has a mix of historic housing near downtown and newer ranch-style homes on its outskirts built from the 1970s through the 1990s. The mix means concrete work here spans the full range - decorative finishes on older historic homes to straightforward driveway replacement on suburban ranch properties. Nearby Elyria to the northeast is the county seat and a larger city with a similar pre-1960 housing profile, and Amherst to the north sits along the Lake Erie shoreline corridor with its own set of clay soil and drainage conditions our crews know well.
