Basement waterproofing in Big Beaver corridor and Somerset, Troy

Updated October 20, 2026

The Big Beaver corridor and the Somerset area are the most built-over part of Troy: offices, condos, townhouses and newer poured foundations on ground that has been graded and regraded for decades. The soil survey calls it urban land, which means every lot is different and the construction details matter more than the map.

Where: central Troy · Housing: newer poured walls, condos and townhouses · Mapped soil: heavily reworked urban land

What contractors usually find in Big Beaver corridor basements

• Tie-hole and cold-joint leaks in poured walls, common in the first ten years.
• Condo and townhouse shared walls where the leak belongs to the association, not the unit.
• Sump discharge and downspouts tied to storm lines that silt up.

Which fix usually fits

• Crack repair: Injection of tie holes and cold joints is the bread-and-butter repair for poured walls.
• Sump pumps: A check of the pump, the discharge line and where it connects is often the whole fix in a newer house.

Also on this site: waterproofing, 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. Check whether your association covers foundation and exterior drainage before requesting an estimate.
2. Look for round tie holes or a horizontal line (cold joint) where the leak starts.
3. Note the age of the pump and whether it has a backup.
4. Find out whether the discharge ties into a storm line.

Big Beaver corridor questions

I'm in a condo. Can I still use the form?

Yes, but find out what your association covers first; many Troy associations handle foundation and drainage work themselves.

Is a leaking tie hole serious?

No. It is a sealed void in the concrete that lost its plug. Injection fixes it permanently.
