Basement waterproofing in Worthington, Ohio

Mid-century block foundations and decades-old footing drains.

Worthington is one of the older suburbs on the north side, and Old Worthington dates back to the early 1800s. Most of the city's housing, though, is mid-century: brick ranches, split-levels and two-stories from the 1950s through the 1970s, many with concrete block foundations. Those homes have had 50 to 70 years of central Ohio freeze-thaw cycles and wet springs, and many of them show it.

What's typical in Worthington basements

• Block walls with efflorescence (white mineral deposits) and damp mortar joints.
• Stair-step and horizontal cracks in block walls, which call for a structural evaluation, not just sealing.
• Original clay-tile footing drains that may have collapsed or silted up after decades.
• Floor drains that back up in heavy storms. That may be a sewer-lateral issue rather than groundwater, so mention it, because it changes who you need. A plumber with a camera may be the first call.
• Large mature trees whose roots and leaf load affect gutters, grading and lateral lines.

Split-levels and partial basements

Many Worthington split-levels have a lower level only partly below grade, and sometimes a crawl space next to it. Water problems there can start in the crawl space or at the joint between the two foundations, so make sure the inspection covers both.

Older-home considerations

Breaking out concrete and disturbing old finishes in mid-century homes can raise questions about older materials. Ask the contractor how they handle dust control and any suspect materials. Worthington's historic district has design review for exterior changes, and that can matter if exterior excavation or visible drainage work is proposed. Check with the city before work begins.

Before you call

Note whether water comes through the walls, up through the floor, or out of the floor drain. That one detail helps a contractor tell a groundwater problem from a sewer problem, and saves you from paying for the wrong fix.
