Concrete Protection System in [Target Location]

Raise, repair and protect your concrete with a complete system designed to address existing damage and help prevent future problems.

Why Does Concrete Crack, Settle and Deteriorate?

Concrete is strong, though it faces constant exposure to conditions that can cause damage over time. Water can seep into porous concrete and the soil below, while freeze-thaw cycles, erosion and shifting soil can contribute to cracking, settlement and surface deterioration. Cracks and open joints can let even more water reach the concrete and soil beneath it, adding to the potential for further damage.

Protecting your concrete means dealing with these problems at the source, not just changing how the surface looks.

Symptoms

Signs Your Concrete Needs Repair and Protection

Concrete damage can show up in different ways depending on what’s happening to the concrete itself, the soil beneath it and the amount of moisture and weather exposure it receives. Some signs seem cosmetic at first, while others can impact drainage, safety or the long-term condition of the concrete.

Signs it might be time to repair and protect your concrete include:

  • Cracking concrete or widening cracks
  • Sinking, settling or uneven slabs
  • Gaps or deteriorating joints between slabs
  • Water pooling on or around concrete
  • Pitting, flaking or other surface deterioration
  • Stains or discoloration

Our Concrete Repair and Protection Solutions

  • For Sinking, Settled and Uneven Concrete

    Concrete Leveling

    Settled concrete doesn’t always need to be replaced. PolyLevel® uses a lightweight polyurethane foam injected beneath the slab to fill voids and bring settled concrete back toward its original position. The process can be used on driveways, sidewalks, patios and other concrete surfaces with less disruption than traditional replacement.

    • Lifts and levels settled concrete
    • Helps limit uneven surfaces and trip hazards
    • Fills voids beneath the slab
    • Lightweight polyurethane won’t add significant weight to underlying soil
    • Small injection holes limit disruption to the concrete
    • Cures quickly so the surface returns to service sooner
    • Works for residential and commercial applications

  • For Cracks, Gaps and Open Joints

    Concrete Caulking

    Cracks and open joints give water a route to the soil beneath your concrete, where erosion and soil movement can lead to settlement. NexusPro® is a flexible concrete sealant applied to seal cracks and joints in concrete while standing up to changing temperatures and weather exposure.

    • Seals cracks and joints against water intrusion
    • Stays flexible as concrete expands and contracts
    • Resists cracking, bubbling and drying out
    • Stands up to UV exposure and changing weather
    • Helps protect the soil under concrete from water
    • Creates a clean, finished appearance
    • Suited to residential and commercial concrete

  • For Porous, Weather-Exposed Concrete

    Concrete Sealing

    Concrete is porous, allowing water and other contaminants to soak into the surface and contribute to deterioration over time. SealantPro® penetrates the concrete and permanently bonds with it, helping shield concrete from moisture, chemicals and the damaging effects of repeated freeze-thaw cycles.

    • Protects against water and moisture intrusion
    • Helps reduce damage from freeze-thaw cycles
    • Stands up to stains from oils and other contaminants
    • Soaks in and bonds with the concrete
    • Won’t peel or flake the way topical coatings do
    • Helps extend the life of existing concrete
    • Suitable for residential and commercial surfaces

  • For Worn, Stained or Dated Concrete

    Concrete Coatings

    Once the necessary concrete repairs are complete, a coating or resurfacing system can give the surface a new look while adding another layer of protection. Depending on the system chosen, coatings can update residential and commercial driveways, patios, walkways, pool decks and other concrete surfaces with decorative finishes built to withstand everyday use and weather exposure.

    • Renews worn or outdated concrete
    • Offers a variety of colors, textures and finishes
    • Helps protect against moisture, stains and everyday wear
    • Produces an easier-to-clean finished surface
    • Can be installed on a variety of concrete surfaces
    • Options available for residential and commercial properties

Benefits of Concrete Repair and Protection

Get More Life Out of Your Concrete

Correcting settlement, cracks, open joints and surface deterioration can help preserve concrete that is still in repairable condition.

Improve Safety

Leveling uneven concrete can reduce tripping hazards on sidewalks, driveways, patios and other walking surfaces.

Help Prevent Further Damage

Sealing joints, cracks and porous surfaces helps limit water infiltration that can contribute to soil movement and concrete deterioration.

Boost Curb Appeal

Repairing cracks, uneven slabs and worn surfaces can improve the appearance of driveways, patios, walkways and other concrete around your property.

Why Repair Concrete Instead of Replacing It?

Tearing out and replacing damaged concrete doesn’t always address what caused the problem in the first place. When underlying soil conditions, water intrusion or unsealed joints aren’t addressed, new concrete can eventually run into similar problems.

If the existing concrete is still repairable, repairing it is often less expensive and causes less disruption than tearing out and replacing the slab. Concrete repair can address settlement, cracks, open joints and other vulnerabilities while saving the concrete you already have.

Don't just take our word for it

See what our customers have to say about our work.

NV Waterproofing was extremely responsive and 100% committed to identifying our water problem and designing a solution. Their work was excellent. The crew was on time and organized. They were very careful to protect the exterior landscaping and the interior of our home from dirt and debris. Even two years later, they responded to a sump problem at no additional charge. NV Waterproofing does the job right and stands behind its work.

Mike and Lynn F. | Columbia, MD

We bought a house in a state of disrepair, and so we've had to work with a number of contractors. I'd rank this company at the top of the list for their professionalism, knowledge, experience, and honesty. We had bowing of our basement walls that needed to be addressed. Michael came out to assess the situation, and gave us some options. After speaking with him, I felt very confident in their ability to buttress our walls. It was also a huge bonus that we were able to set up a payment plan for this job too. When the team showed up, Casey, Kevin, and Grant, they were super polite and professional. They took great care of our property, and if they had a question about anything, they asked. Also, if I had a question, Casey (the foreman), was very knowledgeable and quick to answer. They presented the work as they progressed through the job, and really, I was actually a little blown away by the scale of the project, and the speed at which they worked. What an impressive job they did! We're very confident in the work they did and will hire them again.

Ellen M.  | Takoma Park, MD

We were referred to NV Waterproofing from my brother-in-law who used them and was pleased. They came out and gave us an estimate - they were very prompt. We had the work done - it looked great and I am sure will do the job (only time will tell). We did have a miscommunication with the work (mostly on our part), but the owner had it fixed promptly and without additional cost. I would highly recommend them to anyone with water issues in their basement.

Susan C. | Washington DC, DC

NV stuck with me and made sure I was happy. Roberto Jr kept me calm as my problem persisted and kept working on a solution beyond the obvious. I highly recommend. Looking forward to a dry basement this summer.

Dean R. | Washington, DC

I am writing this letter to commend members of your organization for the waterproofing work performed on and around the foundation of my house. Despite situations beyond the control of both me and your associate, he always maintained professionalism and demonstrated why he is an outstanding representative of your organization. The crew obviously knew what had to be done and went about doing it. They were prompt in arriving at work each day, diligent in the performance of their duties (in spite of high heat and humidity), and took measures to ensure the safety around the excavated area (important because of children in the neighborhood). Unlike other construction sites I have seen, the crew maintained the area free of litter— no small measure these days! In addition, the crew always provided clear explanations of the work to be done each day, answering the questions with forthright and clear responses, never hurrying the discussion. As I was not on site while work was being done, they called me several times, taking those extra steps to keep me informed of the status of the work and aware of the tasks yet to be performed— something that is greatly appreciated. I would appreciate it if you would offer my heartfelt thanks to your able crew for the quality waterproofing work performed and the excellent communication and coordination exhibited by them.

Myra L. | Washington, DC

In my 12 years of having NV Waterproofing as a business partner, they have always proved reliable and trustworthy. They are a great value for me and my customers.

Darryl O. of Brookfield Homes, | Washington, DC

Great professional service and able to respond in timely manner to the project need.

Blake B. | Washington, DC

Brendan was very knowledgeable, professional and courteous. Highly recommend.

Cesar T. | Arlington, VA

A brief note to thank NV Waterproofing for extreme professionalism and courtesy in the manner in which my recent basement water seepage problem was addressed. From the initial contact with Jim, through the work with Roberto, Carlos and Jose, it was an overall pleasant experience – not to mention my contact with the owner and his responsiveness.

Ramesh T. | Arlington, VA

These guys were amazing. The initial visit was smooth, not pushy at all and he was even able to accommodate the relocation of a small drainage pipe. The demo to install the system was done beautifully, yes it was really good, you can tell they were precise and careful when doing so. Everything was clean, no stains on my carpet and they protected everything. No leak so far and I love it. Did I mention the price was excellent? I had 3 other companies to estimate thousands and even tried to sell extra unnecessary equipment. Thank you NV Waterproofing I have and will continue to recommend you.

Chelly Z. | Falls Church, VA

We appreciated NV Waterproofing's honesty and the men who worked tirelessly in uncomfortably cold weather. We've had one big storm since they finished and the basement walls are nice and dry. Nice work!

Peter V. | Falls Church, VA

Mauricio and Cristian were the initial sales reps who came to examine the issue and they took the time to test drainage that might have potentially been creating the water issue. They offered a reasonable solution (sealing the visible cracks and holes in the concrete) and I was contacted within a couple of days with an estimate and scheduling options. Sean was our tech and he did a fantastic job diagnosing the issue beyond just the cracks. He not only address all the holes and cracks in the concrete and mortar, he sealed up additional entry points above the foundation. He sourced additional materials to cover openings for cable lines. He went above and beyond and gave us measured information on how we should continue to monitor and treat this area as the house settles. He was thorough, informative, and provided excellent service in his work. I'm very glad that Sean was the technician sent to us and I would specifically request him for your projects.

  • Sunken Concrete Step Repair in Stephens City, VA

    This Stephens City, VA homeowner was dealing with a sunken concrete front step that had settled over time, creating an uneven entryway and a noticeable tripping hazard near the front door. Sunken concrete steps can make everyday foot traffic unsafe for homeowners, guests, and delivery drivers, while also taking away from the home’s curb appeal. Our concrete repair team lifted and leveled the front step back to its proper position, creating a safer, more stable walkway and entrance. This concrete step repair helped reduce the risk of falls, improved the look of the front entry, and gave the home a cleaner, more welcoming appearance. The homeowner was thrilled with the outcome — a big transformation that improved both safety and curb appeal!

  • Basement Waterproofing in Winchestor, VA

    A homeowner in Winchester, VA, was struggling with a failing sump pump that couldn’t keep up during heavy rainstorms, leaving their basement vulnerable to water intrusion. The lack of a reliable backup system also left them worried about potential flooding during power outages. Frustrated and seeking a dependable solution, they contacted NV Waterproofing and Foundation Repair, a trusted basement waterproofing company in Winchester, VA.

    After assessing the situation, we replaced their old sump pump with a state-of-the-art TripleSafe Sump Pump system. This advanced system includes three levels of protection: a primary pump, a secondary pump for heavy water flow, and a battery backup to ensure the basement stays dry even during power outages. The homeowner now has peace of mind knowing their basement is fully protected, no matter the weather.

  • Pool Deck Leveling in Manassas, VA

    A homeowner in Manassas, VA, quickly realized their dream backyard pool was at risk when the surrounding concrete pool deck began to show serious problems. Uneven and sunken slabs created tripping hazards and unsightly cracks, making both safety and aesthetics a challenge for anyone using the space. Additionally, water from rain and pool use was pooling in low spots, causing slippery surfaces and further soil erosion beneath the deck. These issues not only threatened the safety of family and guests but also compromised the value and enjoyment of the home.

    Seeking an effective solution, the homeowner reached out to our team for a professional assessment. We identified the main cause of settlement: soil erosion under the slabs—a common issue in Manassas due to its clay-rich ground and fluctuating moisture. To address both the immediate hazards and prevent future damage, we recommended our two-part approach: the cutting-edge PolyLevel® concrete leveling system and NexusPro® Joint Sealant.

    The repair process began with drilling small holes into the affected concrete slabs, allowing us to inject high-strength PolyLevel® polyurethane foam beneath the surface. As the foam expanded, it filled voids, stabilized the soil, and gently lifted the slabs back to their original positions. The process was quick, clean, and minimized disruption, giving the pool deck a level, safe surface once again. PolyLevel® foam is waterproof and lightweight, reducing the risk of future settling and ensuring long-term durability, even in a wet poolside environment.

    To provide further protection, we sealed all cracks and joints with NexusPro® Joint Sealant. This flexible, weather-resistant sealant prevents water from seeping beneath the slabs, protecting the soil and concrete from additional erosion. The result was a clean, finished appearance that not only improved the look of the deck but also safeguarded it for years to come.

    Thanks to modern concrete leveling technology, the homeowner’s pool deck was transformed from a liability into a safe and attractive outdoor gathering space. The project was completed in a single day, with minimal mess and immediate results, giving the homeowner peace of mind and renewed pride in their backyard. If you’re facing similar issues with your pool deck in Manassas, VA, the PolyLevel® system and NexusPro® Joint Sealant offer a fast, effective, and lasting

Frequently Asked Questions

Does NV Waterproofing and Foundation Repair warranty concrete repair and protection? 2026-10-05T17:27:52-05:00

Warranty coverage varies by contractor, product and repair performed. Check with your NV Waterproofing and Foundation Repair concrete repair specialist about the warranty coverage included with your recommended system. 

What maintenance does repaired and protected concrete need? 2026-10-05T17:27:23-05:00

Maintenance depends on the repair and protection systems installed. Keeping concrete clean, maintaining proper drainage and catching new damage early can help preserve the repaired surface. Your NV Waterproofing and Foundation Repair installer can provide maintenance recommendations based on the products used and conditions around your concrete. 

Can old or damaged concrete be coated after it is repaired? 2026-10-05T17:26:58-05:00

In many cases, yes. Existing concrete should be evaluated and any necessary repairs completed before a coating is installed. Settlement, cracks or other damage may need correcting first so the coating is applied to a properly prepared surface. The condition of the existing concrete will show whether it is a good candidate for coating. 

Will sealing concrete help protect it from water and freeze-thaw damage? 2026-10-05T17:26:32-05:00

Yes. Concrete is porous, so moisture can enter the surface and contribute to pitting, flaking and cracking, especially as temperatures repeatedly freeze and thaw. A penetrating concrete sealant helps limit moisture intrusion and protects the concrete from weather, chemicals and seasonal changes. 

How long does concrete repair take, and when can I use the surface again? 2026-10-05T17:26:07-05:00

Most concrete repair projects can be completed in a day, although the schedule depends on the size of the project and repairs being performed. PolyLevel® cures quickly and usually supports normal use shortly after installation. Caulking, sealing and coating systems each have their own cure times, so your installer will confirm when the finished surface is ready for foot or vehicle traffic. 

What affects how long concrete repairs last? 2026-10-05T17:25:41-05:00

The longevity of a concrete repair depends on the condition of the slab, the soil and drainage conditions, the type of repair and ongoing exposure. Products such as PolyLevel®, NexusPro® and SealantPro® are designed for long-lasting concrete repair and protection. Your contractor can explain the expected performance and warranty for the solutions recommended for your property. 

Can concrete leveling, caulking and sealing be done at the same time? 2026-10-05T17:24:42-05:00

Yes. These solutions are built to work together as part of a complete concrete protection system. If needed, the concrete is first lifted and leveled with PolyLevel®. Next, cracks and control joints are sealed with NexusPro®, then SealantPro® to protect the concrete surface from moisture, chemicals and seasonal changes. 

Can cracked or sinking concrete be repaired without replacing it? 2026-10-05T17:24:09-05:00

In many cases, yes. Settled concrete can be lifted and stabilized with PolyLevel® polyurethane foam instead of being removed and repoured. Cracks and control joints can then be sealed with NexusPro® to help prevent water from reaching the soil below. Whether a slab can be repaired depends on its condition and the extent of the damage. 

Is it better to repair or replace damaged concrete? 2026-10-05T17:23:37-05:00

When the existing slab is still in repairable condition, concrete repair can often cost less and be less disruptive than tearing it out and replacing it. Repair also lets underlying settlement, open joints and other vulnerabilities be addressed. Severely deteriorated or structurally damaged concrete may require replacement, so a professional inspection can help identify the appropriate approach. 

What does a concrete protection system include? 2026-10-05T17:23:02-05:00

A complete concrete protection system can address several causes and symptoms of concrete damage. PolyLevel® polyurethane foam lifts and levels settled slabs, NexusPro® seals cracks and control joints to help block water, and SealantPro® bonds with the concrete to protect it from moisture, chemicals and seasonal changes. The solutions needed depend on the condition of your concrete. 

How much does a concrete protection system cost in [Target Location]? 2026-10-05T17:22:10-05:00

Pricing for a concrete protection system depends on how much concrete you have, its condition and the repairs needed. Sunken slabs may need leveling, while cracks and open joints may need sealing before the surface is protected. NV Waterproofing and Foundation Repair can inspect your concrete and give you a written estimate based on the recommended repairs.
