Concrete Slab Repair Solutions
for a Safe, Level Home

Cracks in a concrete slab or driveway are more than ugly to look at. They’re a sign of movement under the surface. In the Carolinas, changing soil conditions and seasonal moisture swings make slab cracks a common headache for homeowners. And while many people try DIY sealing methods with store-bought epoxies, those products don’t hold up over time. Moisture Loc repairs cracked slabs permanently by reinforcing the concrete from within.

  • Stop active cracks from widening
  • Strengthen weakened slab sections
  • Prevent future movement and structural damage

Concrete appeal is curb appeal.

Why Concrete Slab
Repair Matters

When concrete cracks, it’s usually because the soil underneath has moved. A lack of water causes soil to shrink. Heavy rains cause it to expand. We get both of those weather phenomena every year in the Carolinas. Over time, they take a toll on concrete. What starts as a hairline crack can turn into a tripping hazard, an entry point for moisture, and a definite eyesore.

Moisture Loc determines the cause of the crack, stabilizes the compromised area, and reinforces the slab so the problem doesn’t return.

Concrete Knowledge Runs
in the Family

Moisture Loc is proud to be the sister company of Doggett Concrete, one of Charlotte’s most trusted names in concrete work. We’ve grown up alongside them, solving problems in the same neighborhoods and working with the same Carolina soil for decades. That connection gives us uncommon insight into how concrete behaves, shifts, cracks, and settles in this region. When we repair a slab, stabilize a wall, or assess a foundation, we’re drawing on deep, local concrete expertise that most waterproofing companies simply don’t have.

Concrete Crack Loc System

Cracked Concrete Slabs or Driveways

Simple epoxy patches won’t prevent an active, moving crack from reopening. Moisture Loc offers a permanent solution without needing further foundation repair services or excavation. Our Concrete Crack Loc System works within your foundation to seal cracks and openings while preventing future slab movement.

Our system reinforces the slab using high-strength carbon fiber staples embedded across the crack line. These staples provide a sealing remedy for compromised structures. If the concrete starts to shift, the carbon fiber staples will absorb the force and keep the crack from reopening. The strength of the staples will stop further movement and reinforce the weaker areas of the concrete.

  • Internal reinforcement, not just an adhesive
  • Long-term durability
  • Fast, non-invasive installation

Why Choose Moisture Loc

Nothing cookie-cutter. Never a franchise.

  • Family-owned and run since 1988. Moisture Loc has served local homeowners and builders for nearly 40 years. When you work in the same community for that long, you get to know it from the ground up. That’s why there isn’t a crawl space or basement issue we can’t solve.
  • We do it right, or not at all. That means finding the real problem, fixing it the right way, and standing behind the work and warranty. It also means pulling the required permits that others skip. Every job gets its own right solution, done to the standard your home deserves, and we demand.
  • You can breathe easier. When 40% of the air you breathe at home comes from your crawl space, you want to know it’s clean. Our encapsulation and waterproofing solutions keep humidity, mold, and wood rot out and a sense of security in. Plus, our foundation and structural solutions preserve the integrity and value of your home while delivering the peace of mind every homeowner wants.
  • This means more to us. We’re rooted here, not spread across states or managed by investors. With one office and one team, the work stays close and personal. Every job means more when you live in the community you serve. We don’t answer to anybody but our customers, the way it should be.

Carlos was very quick to respond with an emergency issue with my listing! As a realtor I need trusted sources to get ahold of with questions and help asap when things may go wrong. Will use Carlos again! Thank you.

After purchasing my home, I started noticing cracks in the drywall, just a few months later. After finding out the house had structural issues, I interviewed several companies and decided to go with moisture lock. If your dealing with structural issues, I highly recommend Moisture lock for their expertise and customer service. Carlos, James and Scott were excellent. I am very pleased with my experience and the work they did to my home.

I have nothing but good things to say about Moisture Loc. I was referred to them by a friend/neighbor, and they did not disappoint. Carlos was thorough in his initial inspection and project recommendations. There were no surprises. I felt like Carlos was honest when he gave us a quote for the work, and that was very important to me. James came with his crew to actually perform the work, and he was equally as outstanding. The work was completely efficiently and properly, and all projects passed Mecklenburg County inspection the first time around. I couldn't be more pleased and highly recommend this company!

These guys did a great job! We had a moisture issue under the house which was messing up our hardwood floors. I had 2 other companies out and then spoke with my neighbor, who is a contractor. He highly recommended Moisture Loc. They didn't try and sell me on things that were not needed and came in less than the other 2 companies. Their work crew was on time and respectful and pleasant. The job is complete and I'm impressed. Highly recommend!

Got 4 local quotes for encapsulating the crawl space of our home. This was a no-brainer, Moisture Loc was heads and tails above all others. Dan Richert was extremely professional, clear and to the point, no up sale, and answered all questions. Everyone involved including Rich Goldman and Brandon Cook were also extremely professional, knowledgeable, and very responsive. Everything was on time. And thanks Ryan (office person) for being there and answering the phone! (seems to be a lost art these days). Highly recommend these folks!

I am a realtor working on behalf of my buyer client to source quotes for repairs. Carlos has been extremely responsive and knowledgeable about his scope of work. I appreciate his honesty in not trying to upsell me on a sump pump because I recieved quotes from multiple crawlspace companies and called to inquire further about this. He was transparent from the beginning and explained why it was not necessary for this particular property, even before I had the chance to ask him. Thank you for your efforts to earn my business. I appreciate you putting the customers needs before your own pocket and look forward to doing continued business with you!

Had a great experience with Moisture Lock. They installed Helical Piers and re-encapsulated my crawlspace. Jerry was an absolute powerhouse for installing the piers. His knowledge and skills are off the chart. The crawlspace work was great as well - Moisture Lock came in a fixed a botched job that was done by Carolina Crawlspace Pros who are now out of business. Everything is in good order now and these guys did a really great job.
