Get matched with top concrete repair specialists in Rangely, CO

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.

Most single-story homes don't have foundations strong enough to support a second story, but they can be reinforced for an addition. A structural engineer can assess your foundation and what needs to be done to get it ready. They'll look at any cracks or unevenness in your current foundation and consider any special framing or beams your home needs, especially if it’s in a high-wind or hurricane area.

“To support a second story, many structural engineers will require that you install additional concrete piers in the crawlspace,” says Tschudi. “This involves hand excavating, pouring a large concrete footing—usually with specially coated rebar—and then building concrete piers right up to the girders.”

While it can be difficult to identify a bad foundation at first glance, look for large horizontal cracks, discoloration, bulging basement walls, or signs of water damage. You may also see large gaps between the home and the foundation on the outside or signs of pooling water from a recent storm.

The average home foundation lasts between 80 and 100 years, but some can last much longer with proper maintenance and routine inspections. The lifespan depends on the foundation type, soil conditions, climate, and construction quality. Poured concrete walls can last up to 200 years, brick or stone foundations over 100 years, cement block foundations 80 to 100 years, and pier foundations about 75 years. Factors that can shorten a foundation's life include expansive clay soil, poor weather conditions, low-quality building materials, improper construction, and tree roots. Signs of damage include sloping floors, bowing walls, cracks, and doors or windows that stick.
