Q: How do I know if my foundation is slab-on-grade?

• <div><p>If you don&rsquo;t have any access to or knowledge of any area underneath your home, chances are it&rsquo;s built slab-on-grade. You can also look for the concrete around the bottom edge of your structure; if it&rsquo;s just a few inches tall, it&rsquo;s likely a slab. If it&rsquo;s more than that, has any windows, or you have steps leading to your main entrance, you likely have a different foundation style.</p></div>

Q: How do you know if a concrete crack is serious?

• <div><p>Although some concrete cracks are cosmetic, others can be more serious. Cracks wider than ⅛ inch or that extend through the slab are serious and can cause structural damage. If you notice these types of cracks in your concrete patio, contact a local contractor <a href="https://www.angi.com/articles/who-installs-concrete-patios.htm">who installs concrete patios</a> to inspect the damage and determine how to fix it. </p></div>

Q: How can you tell if a concrete job is bad?

• <div><p>Visible cracks, scaling, flaking, and uneven surfaces indicate a bad concrete job. Additional signs vary depending on the project. You may notice poor drainage or even exposed rebar. Quality issues result from using the wrong concrete, rushing the work, or inexperienced workers completing the job.</p></div>

Q: What are the warning signs of a serious concrete crack?

• <div><p>Minor hairline cracks in your concrete may not look pretty, but they&rsquo;re often not serious. It&rsquo;s when concrete cracks are larger&mdash;wide enough that you can slide a credit card into it&mdash;that you need to worry. If you monitor a crack and can trace its active expansion over time, you&rsquo;ll definitely want to call in a pro to inspect it and, potentially, repair it. Want to prevent cracks in your garage and driveway concrete in the future? Stay on top of sealing. Here&rsquo;s how to seal your concrete garage floor and driveway.</p></div>

Q: How long does efflorescence damage a concrete slab?

He started with a price of $380 which was a bit high and then he said he found another problem after he started. Now it is $500 dollar repair on an $800 six yr old fridge. I could have spent another $400 and had a new one. Will not use him again.
