Concrete Repair questions, answered by experts

Barring extreme home foundation problems, most horizontal foundation cracks are fixable using one or more methods. Most of the repair methods require professional expertise to accomplish, and include plate anchors, steel reinforcement, soil anchors, reconstruction, or carbon fiber strip applications. Contacting a professional to diagnose the problem early can minimize repair expenses.

Minor slab leaks normally take around three hours to access and fix, provided the leak is in an accessible location. However, a more extensive leak or a leak in a hard-to-reach location can take several days to fix, depending on the resulting damage. You might also want to consider the timeline for the build-back if the leak damages building materials like flooring or cabinets, which can take several weeks, including delivery of the materials.

Some foundation repairs are permanent, like underpinning and exterior drainage systems like the French drain. These fixes address the underlying problems—insufficient support from the soil and hydrostatic pressure on your foundation walls, respectively—so they can last for many decades, making them “lifetime fixes.” There are other solutions to address these issues that will last for up to a decade, making them temporary. These include slabjacking to raise concrete slabs back into place and dampproofing to reduce the water in the soil that interacts with the concrete foundation.

Yes. A foundation wall can usually be replaced, but you’ll want to call a foundation professional.

You can seal a concrete slab by cleaning the surface, filling in any cracks, etching the surface, applying a sealer, and letting it dry. Concrete slabs don't typically need sealing, but you can use a topical concrete sealer if you notice signs of water damage. If you haven't already fixed the cause of the leak, then you'll want to repair the plumbing before you seal a concrete slab.
