How Wall Cracks Get Repaired
The wall itself shapes the repair. In poured concrete, a crack usually runs as one line, often vertical or slightly angled, and the common fix is injection: the contractor sets small ports along the crack, then pumps material in under pressure until it fills the gap from the inside face to the outside. Block walls behave differently. Their cracks tend to zigzag along mortar joints, and injection works poorly in hollow block, so repairs there usually mean sealing joints and managing water with drainage.
Two injection materials do most of the work. Epoxy cures hard and bonds the concrete on both sides, which suits a crack that has stopped moving. Polyurethane foam stays flexible and expands to fill the opening, which suits a crack that leaks but may still shift slightly with the seasons. The estimate should name the one chosen for each crack.
What Gets Done
- Hairline cracks. Thin cracks in poured walls are common as concrete cures and shrinks. Many stay dry; the ones that darken after rain are the usual candidates for injection.
- Stair-step cracks in block. Cracks that climb along mortar joints can let water into the hollow cores. Repairs often pair joint sealing with weep holes and a drain.
- Horizontal cracks and bowing. A crack running sideways along a wall, or a wall that leans inward, is worth having looked at soon by a contractor who handles wall repair.
- Cracks that seem to grow. Pencil a mark and the date at each end. If the crack passes the marks over the following months, mention that in your request.
- Leaking cracks. Injection fills the path water takes through the wall, working from inside the basement with no excavation.

How the Work Usually Goes
- Record the crack. Photograph it with a tape measure in the frame, and note its direction and whether it gets wet.
- The visit. The contractor measures the crack, checks it for moisture and looks over the rest of the wall.
- A written estimate. It lists the number and length of cracks, the injection material, any drainage suggested and the warranty terms.
- Permits. Sealing a crack generally needs no permit. If a sump or drain is added, plumbing or electrical permits can apply, so ask the contractor and, in Columbus, Building and Zoning Services.
- Prep and injection. Ports are fixed along the cleaned crack, the face is sealed with paste, and material goes in from the lowest port upward.
- Cleanup. Once the material sets, the ports are trimmed and the line is left neat.
Why Homeowners Use This Service
Crack injection is one of the smaller basement jobs, done from inside without digging up a flower bed. In Columbus, many older homes near downtown stand on block or brick, while many mid-century ranches and newer suburban houses sit on poured walls, so the approach varies street by street. Freeze-thaw winters can nudge hairline gaps wider.
Inside city limits, the license to look for is the City of Columbus home improvement license for basement waterproofing, and Building and Zoning Services can confirm it; elsewhere, ask your own building department. Get a written, itemized contract and skip anyone who wants cash or full payment upfront. Ohio lets you cancel a sale signed at home until midnight of the third business day.
Foundation Crack Repair Questions, Answered
Are hairline cracks in a basement wall normal?
Thin vertical cracks are common in poured walls as concrete dries and shrinks, and many never leak. Check them after heavy rain. If one turns damp, leaves a white chalky line or starts to widen, that's a sensible time to have a contractor take a look.
Should I worry about a horizontal crack?
A horizontal crack, a wall that bows inward or a crack that keeps widening is worth having looked at soon. This site can't say what it means for your house. A contractor who handles wall repair can look at it in person and explain what they recommend, and you can ask for that in writing.
Which is better, epoxy or polyurethane injection?
Each has its place: epoxy for a crack that has stopped moving, polyurethane for one that is mainly a leak. A contractor picks based on the crack's width, whether it's wet and whether it moves, and should say why on the estimate.
Can I seal a crack myself with a store kit?
Some homeowners patch small, dry cracks with a kit. Surface patches often fail on a crack that's actively leaking, because water pushes behind them. If a crack lets water in after every storm, a contractor's opinion usually saves a round of trial and error.
