Concrete Sealing Services in [Target Location]

Protect and add years to your driveway, patio, walkway and other concrete surfaces with expert concrete sealing.

What Is Concrete Sealing?

Concrete sealing is the practice of applying a protective sealant that helps stop water, salt, oil and other contaminants from absorbing into your concrete and contributing to damage.

Many store-bought and topical concrete sealers form a film on the surface that can wear away over time. NV Waterproofing and Foundation Repair uses a penetrating concrete sealant that soaks into the pores of the concrete, offering long-lasting protection from the inside out.

Why Seal Your Concrete?

Concrete is porous, so water, salts and other contaminants can soak in. When moisture gets into the concrete and repeatedly freezes and thaws, the expansion can gradually weaken the surface, contributing to pitting and flaking. Concrete sealing helps cut down that absorption, shielding the surface against moisture, deicing salts, oil and other contaminants that can accelerate deterioration and shorten the life of your concrete.

Our Concrete Sealing Solutions

  • For Protection from Flaking, Pitting & Staining

    SealantPro® Penetrating Concrete Sealant

    SealantPro® is a penetrating concrete sealant formulated to protect driveways, patios, sidewalks, garage floors and pool decks. Rather than forming a coating on top, it penetrates the concrete to help limit the amount of water, deicing salts, oil and other contaminants that can soak into the surface and contribute to staining and surface deterioration.

    • Penetrates into concrete rather than forming a surface film
    • Helps protect against water and moisture intrusion
    • Reduces penetration of deicing salts and other contaminants
    • Helps protect against pitting, flaking and staining
    • Won’t peel or flake like a surface coating
    • Works on driveways, patios, sidewalks, garage floors and pool decks

What To Expect

What to Expect When NV Waterproofing and Foundation Repair Seals Your Concrete

Repair First. Protect Second.

Concrete sealing performs best when the surface is in good condition. If your concrete has sunken, PolyLevel® can be used to lift and level the slab before sealing. Open cracks and control joints can also be closed with NexusPro® to help keep water from reaching the soil below.

Once repairs are complete, SealantPro® helps protect the concrete against water, deicing salts and other contaminants that can drive surface deterioration.

  • 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

Can stamped or previously sealed concrete be sealed? 2026-10-05T17:16:14-05:00

Sometimes, yes. Stamped concrete may have a topical coating or other finish, while previously sealed concrete may have residue on the surface that affects how a penetrating sealer can absorb. The existing finish and condition of the concrete need to be evaluated first to see whether additional preparation is needed and whether penetrating concrete sealing is appropriate. 

When should new concrete be sealed? 2026-10-05T17:15:40-05:00

New concrete needs time to cure before a penetrating sealer is applied. The right timing can depend on the concrete, weather conditions and the sealer being used. NV Waterproofing and Foundation Repair can evaluate new concrete and determine when it’s ready for sealing without interfering with the curing process. 

How long does concrete sealing take, and when can I walk or drive on it? 2026-10-05T17:15:01-05:00

How long installation takes depends on the size and condition of the area being treated, including the surface preparation required before sealing. Once SealantPro® goes on, it needs roughly six hours to cure before the treated concrete can return to normal use. Your installer will provide specific instructions based on the conditions and application. 

What happens if you don’t seal your concrete? 2026-10-05T17:14:34-05:00

Unsealed concrete absorbs water, deicing salts, oil and other contaminants. Over time, moisture and repeated freeze-thaw cycles can lead to surface deterioration, including pitting and flaking. Not every unsealed surface develops damage, but sealing adds a layer of protection that can help preserve concrete exposed to moisture, weather and salts. 

How much does concrete sealing cost in [Target Location]? 2026-10-05T17:14:04-05:00

Concrete sealing costs vary depending on how large and how worn the area is, the surface preparation required and the type of concrete being sealed. Cracks, uneven slabs or other damage requiring repair before sealing can also affect the total project cost. NV Waterproofing and Foundation Repair offers a free inspection and written estimate based on your concrete. 

How often should concrete be sealed? 2026-10-05T17:13:38-05:00

How often concrete needs sealing depends largely on the type of sealer used. Topical sealers sit on the surface and may need reapplication as they wear, while penetrating sealers typically provide longer-lasting protection from within the concrete. Weather exposure, traffic and the condition of the surface can also affect when resealing is needed. 

Is concrete sealing worth it? 2026-10-05T17:13:10-05:00

Yes. Concrete driveway sealing can be a worthwhile way to protect against water, deicing salts and other contaminants, and the same protection can be applied to patios, sidewalks and other concrete surfaces. A penetrating sealer helps limit how much porous concrete absorbs, reducing the conditions that contribute to staining, pitting and flaking. It’s most effective as preventive protection rather than a repair for existing damage.
