How thick should you pour concrete over existing concrete?

• <div><p>Concrete should be at least 2 inches thick to maintain its stability and quality. Most concrete slabs fall between 4 and 6 inches thick, but you should be careful not to make the new slab too high or heavy. If you're considering a stamped concrete overlay, <a href="https://www.angi.com/articles/7-tips-hire-best-stamped-concrete-contractor.htm">hire an experienced stamped concrete contractor</a> to determine the <a href="https://www.angi.com/articles/how-thick-should-a-concrete-patio-be.htm">ideal concrete thickness</a>. </p></div>

Q: What size gravel should you put under a concrete slab?

• <div><p>You should put gravel that is 3/4 to 1 inch under a concrete slab. However, depending on the project, local building codes may dictate the proper gravel size and shape. Some concrete slabs that do not hold significant weight may have a subbase of sand. Also, keep in mind that the subbase you choose will affect the <a href="https://www.angi.com/articles/how-much-does-concrete-patio-cost-square-foot.htm">cost of your concrete patio</a>, walkway, or driveway. </p></div>

Q: Will concrete set in rain?

• <div><p>Yes, <a href="https://www.angi.com/articles/pouring-concrete-in-the-rain.htm">concrete can set in rain</a>, but it&rsquo;s best if you pour concrete 4 to 8 hours before any rain to ensure it won&rsquo;t impact its strength and appearance. Exposure to heavy rain during the early stages (the first 48 hours after pouring) can significantly reduce the structural integrity of the concrete. Over time, cracking is more likely due to softer concrete. </p></div>

Q: How do you know if concrete is fully cured?

• <div><p>You will know concrete is fully cured after 28 days when the new concrete reaches its maximum strength. Follow the cure time information on the manufacturer&rsquo;s label or ask your concrete pro about when your concrete is fully cured. You can drive your concrete once it&rsquo;s partially cured, usually around seven days after it&rsquo;s poured. After one week, the concrete is strong enough to hold up to regular-size vehicles.</p></div>

Q: Should I repair my concrete driveway or have a new concrete driveway installed?

• <div><p>Cost and age are two factors to consider when determining if you should repair or replace your concrete driveway. If your existing driveway is on the older side and the cost of repairs is 50% or more of its value, it might be worth replacing it. Replacing a concrete driveway when it's 20 years old and deteriorating in condition will save you from the cost of repairs that likely wouldn&rsquo;t save it from replacement in a few years anyway. </p></div>

My driveway was totally cracked. I was scared I was going to have to replace the entire driveway. Luckily DryLock Pros was able to use the existing driveway, grind it down, and apply a new surface coat of concrete. My driveway looks brand new. Well worth the money. Highly recommend.
