Basement waterproofing in Dearborn Hills, Dearborn

Updated October 20, 2026

Dearborn Hills near the golf course is 1950s–60s housing on Blount clay, the same soil that bows block walls across the metro area. The common question from Dearborn Hills is not a leak at all but a block wall that has started to lean in at mid-height, with or without a horizontal crack.

Where: near the golf course · Housing: 1950s–60s homes · Mapped soil: Blount clay

What contractors usually find in Dearborn Hills basements

• Horizontal cracks and inward bowing in block walls on the side with the most roof water.
• Seepage at mortar joints when the clay is saturated.
• Sump discharge dumping near the foundation, feeding the clay.

Which fix usually fits

• Crack repair: Wall stabilization (carbon fiber straps or anchors) is the priority; it should be measured before any cosmetic work.
• Waterproofing: Interior drain tile removes the water pressure that drives the bowing.

Also on this site: sump & backwater, crawl space. The contractor decides the scope at the house; these are the usual starting points, not a diagnosis of your basement.

Before you send the form

1. Hold a long level against the wall and note any bow at mid-height.
2. Photograph horizontal cracks and note the wall.
3. Count downspouts on that side and where they discharge.
4. Mention any earlier anchor or strap work.

Dearborn Hills questions

How much bow is too much?

Under an inch is routinely stabilized; past that the options get more expensive. Measure it at the free estimate rather than guessing.

Will fixing the water stop the bowing?

It stops it getting worse. It does not straighten the wall; that is the structural repair.

General notes from Census build eras, USDA map units and the city's own flood pages, not records of specific addresses. More on the Dearborn facts page and the all-areas page.
