How long does concrete take to completely harden?

• <div><p>Concrete can take <b>up to 28 days</b> to completely harden, depending on the type and its water content. But it dries enough for foot traffic in 24 to 48 hours. If you're curious about <a href="https://www.angi.com/articles/how-long-does-concrete-take-to-dry.htm">how long it takes concrete to dry</a> entirely, the answer is more complex, so always check with the specific mixture instructions before adding heavy machinery or driving on new concrete.</p></div>

Q: Can I pour self-leveling concrete over concrete?

• <div><p>Yes&mdash;as long as the area has been properly prepped. Different self-leveling brands and compounds have their own specific instructions for preparation; some may require that you add primer or grind the surface. Without proper preparation of the surface, the compound will not be able to fully bond to the concrete and fill the cure as a separate layer, which makes it prone to chipping.</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: What happens if you don't put gravel under concrete?

• <div><p>If you don&rsquo;t put gravel under concrete, the concrete can crack, sink, bow, or crumble. Even the <a href="https://www.angi.com/articles/concrete-forming.htm">concrete forming</a> process will not go as smoothly if you are working directly on the soil or bare bedrock. The lack of a proper gravel layer can also lead to drainage issues below your slab, leading to water issues throughout your lawn and around your foundation.</p></div>

Q: Can I just use cement on its own?

• <div><p>No, cement cannot be used on its own except for rare circumstances, as it's only a binder to form other products, such as concrete or mortar. Follow the manufacturer's instructions to create a concrete or mortar mix. Concrete, for instance, needs cement, water, and aggregates such as sand and gravel. Using the right amount of water and water temperature is essential to ensure you have the right <a href="https://www.angi.com/articles/concrete-slump.htm">concrete slump</a> and the mix spreads easily and cures well. </p></div>

This company is the absolute worst experience I have ever had. The person who measured for my 12 window replacement estimate Lindsay, measured incorrectly. This caused the disaster from that point forward. When the installers came, the crew were unfriendly and appeared like they were hungover or...
