Sealing Cracks Before Water Gets In
Sealing a crack keeps water, insects and soil from working through the concrete, and it leaves a clean line to watch for new movement. The two common materials behave differently.
Epoxy is a rigid, strong resin. Injected into a dry crack, it bonds the two sides back together, which suits cracks that have stopped moving. Polyurethane foam stays flexible and expands as it cures, so it blocks water in cracks that may still shift a little.
Size matters. A hairline crack, thinner than a credit card, is common as concrete cures and is often cosmetic. A crack about 1/8 inch wide, one wider at one end, or one whose sides no longer line up is worth a closer look, since sealing alone does not deal with movement below.
What Gets Done During Foundation Crack Repair
- Measuring and marking. The specialist notes each crack's width, length and direction, and may mark its ends to see whether it grows.
- Stair-step brick cracks. Cracks that climb a brick wall along the mortar joints can show that one corner of the house has dropped. Floor readings near them help confirm it.
- Epoxy injection. Used on dry cracks that have stopped moving, to join the concrete into one piece again.
- Polyurethane injection. Used where water seeps in or slight movement continues, since the foam flexes and swells to fill the gap.
Budget Figures for Foundation Crack Repair
Sealing one crack is one of the smaller foundation jobs. The price climbs with several cracks, hard access, or a crack that turns out to be part of wider settling. All three rows are national figures from This Old House, not our prices and not a quote.

- Cosmetic or symptom. Floor readings and a look at the drainage help sort shrinkage cracks from cracks tied to settling.

- Injection and cleanup. The repair crew cleans the crack, sets the ports, injects the material and removes the ports once it cures.
Why Homeowners Choose Foundation Crack Repair
Some clays in this part of Texas crack as they dry, and that movement in the ground can show up later in the house. Pullman, a heavier clay soil of the Southern High Plains, can open cracks 5 mm or wider that reach about 84 cm down in dry weather. Randall clay, found on playa floors, can split 0.4 to 2 inches wide and 40 inches or more deep (NRCS).
Dry stretches are no stranger here: June 2011 passed with no measurable rain in Lubbock (National Weather Service). Sealing is often a modest step that keeps water out and leaves a fixed line to watch. If a sealed crack opens again, that tells the specialist something about the ground below.
Foundation Crack Repair Questions, Answered
Is a hairline crack something to worry about?
Usually it is something to note more than worry over. Thin cracks often form as concrete dries and shrinks. Mark the ends with a pencil and the date, then check again in a few months. If it grows or shows up with sticking doors, ask a specialist to look.
Epoxy or polyurethane: which one fits?
It depends on the crack. Epoxy suits a dry crack that has stopped moving, because it bonds the concrete back into one piece. Polyurethane suits a crack that lets water in or may still shift slightly, because the foam stays flexible after it cures. The specialist should explain the choice for each crack in the written estimate.
Can I seal a crack myself?
Store-bought filler can close a thin cosmetic crack and keep out dust and bugs. It will not tell you whether the house moved, and it can cover the very line you would want to watch. For a crack wider than about 1/8 inch, or one with other symptoms, a specialist's look first makes sense.
Does every crack mean the foundation is moving?
Not at all. Concrete shrinks as it cures, and brick and drywall crack with heat and cold. A crack says more when it is wide, uneven or growing, or when it lines up with doors that stick and floors that tilt. Our warning signs quiz can help you sort what you see before the visit.
