Q: What is making my concrete green?

• <div><p>If your concrete stains are green in color, it indicates the presence of mold or algae&mdash;which you should address right away. If left unattended, mold will spread to other areas throughout the home. However, be careful not to disturb mold on indoor concrete surfaces and work with a <a href="https://www.angi.com/nearme/mold-removal/">local mold remediation specialist</a> for specialized care. Once free from mold and algae, seal your concrete to eliminate pores and gaps.</p></div>

Q: Can I pour concrete directly on dirt?

• <div><p>It is not advisable to pour concrete directly on dirt. Even compacted soil&mdash;known as a subgrade&mdash;is not strong enough to maintain the form of concrete. You can, however, <a href="https://www.angi.com/articles/can-you-pour-over-concrete.htm">pour concrete over concrete</a> as long as the overlay has proper bonding agents and the slab below is clear of damage.</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: How often should I water new concrete?

• <div><p>You should water new concrete by spraying it five to 10 times per day for the first seven days. This process of moist curing allows the concrete to become as strong as possible to prevent cracks and weak concrete. Moist-cured concrete is 50% stronger than concrete that was not sprayed with water during the first week. The only exception is if you pour concrete in the winter. Then, spraying with water is not recommended.</p></div>

Q: Can you pour concrete over an existing basement floor?

• <div><p>Yes, you can pour concrete over an existing concrete basement floor to save time and money on fully ripping out an existing concrete slab. However, it&rsquo;s not a perfect solution, so consult a pro before moving forward. You must take specific measurements, and these kinds of floors don&rsquo;t have the same longevity.</p></div>

"I spent a lot of time trying to find someone that could replace my front steps. Getting someone to actually call back was the first challenge. Then, trying to find someone who does everything we wanted: granite steps, faux stone facing and sides, white railings, and the ability to tear up and lower my walkway then redo it to make the first step 7” was an even bigger challenge. We finally found the right guy/company and we are very happy with the results. Walter Santos of W. Santos Construction did it all for us. He started within days of us accepting his proposal. He was kind, communicated the next steps with us well, and the quality was fantastic. I was outside tonight taking photos and a family was taking a walk stopped me to ask who did the steps because “they make the house.” I took some dry and wet pics after the dust was washed off and I’m very happy with the results. He even came out to finish on Memorial Day."

"M&L Landscaping Construction is absolutely incredible! You will not regret hiring Leo and his team for your project. I first hired Leo for one job, and after seeing the quality, precision, and care in his work, I immediately brought him back for a second. The first project included pavers, a retaining wall with built-in seating, a garden bed, patio/paver installation, fence installation, and a composite deck with stairs. The second project was for my rental property and involved an insurance claim to repair the facade of the house. That work included installing stone veneers on the front of my home, constructing a new deck with a roof, building a stone wall with fencing, and completing a blacktop driveway. What truly sets M&L apart is not just the beauty and craftsmanship of their work, but the professionalism, organization, and integrity behind it. Leo’s team is respectful of your property, punctual, and incredibly hardworking. They take pride in what they do and it shows in every detail—from layout precision to cleanup after completion. Equally impressive is how Leo manages the business side of things. He’s communicative, transparent, and extremely reliable—qualities that are rare to find in the contracting world. He provides clear timelines, fair pricing, and proactive updates, so you always know where things stand. Having worked with many contractors over the years, I can confidently say that M&L Landscaping Construction is top-notch from start to finish. I was so impressed that I even referred my parents for their driveway paver installation—and, just as expected, it came out beautiful. If you’re looking for a trustworthy, skilled, and professional landscaping and construction team, hire M&L Landscaping Construction. You’ll be glad you did!"
