Foundation Repair questions, answered by experts

Efflorescence can damage a concrete slab for two to three years. After that, it resolves on its own once the surrounding salts are gone.

Yes, foundation problems can cause ceilings to collapse or even your whole house to crumble. Left unaddressed, natural sinking can build up and eventually harm your home’s supporting structure, such as walls, beams, and frames. Your basement ceiling may be the first place to look for signs of a ceiling collapse caused by foundation problems.

You can use a level or straight-edge to test for plumb foundation walls and a level slab, a level or a ball to check for sloping floors inside your home, and a hygrometer to look for moisture in your underhome area. Aside from these DIY tests, it’s important to get a foundation repair specialist or structural engineer to test the foundation to see if it’s supporting your structure properly. They can determine if the loads on the concrete are uneven or need reinforcement.

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.

Cement companies offer a wide variety of services, including delivering and pouring concrete for home foundations, walkways, patios, driveways, concrete steps, pools, pool decks, and more, plus concrete repair and patching. Most companies also have the ability to demolish and haul away old concrete landscaping features. It’s a good idea to reach out to a few different companies before hiring to make sure you choose one that can tackle the entirety of the project you have from start to finish. This method will typically save you some money over hiring multiple contractors.
