Indiana weather is rough on concrete. Road salt, winter freeze-thaw cycles, summer storms, and groundwater all work their way into the pores of your driveway, patio, garage floor, or pool deck — and once water gets in, damage follows. Cracking, spalling, pitting, efflorescence, and staining are all symptoms of concrete that isn’t properly waterproofed.
At Seal Now, we waterproof concrete the right way: with a deep-penetrating, nanotechnology-based sealer that bonds inside the concrete itself — not a surface film that peels, yellows, or traps moisture. The result is concrete that repels water, shrugs off salt and chlorides, and keeps its natural look for 7–10 years.

We use water-based, nanotechnology penetrating sealer, a water-based, nanotechnology penetrating sealer engineered specifically for concrete, masonry, and porous stone. Unlike topical sealers that sit on the surface and wear off with traffic or UV exposure, Siloxa-Tek soaks into the substrate and chemically bonds with the concrete itself.
Inside the pores, it forms a hydrophobic (water-repelling) barrier that blocks liquid water and dissolved chlorides — while still letting water vapor escape. That breathability is the reason it won’t flake, peel, or cause whitening later on.
Bonds inside the concrete, not on top — the protection can't wear off with traffic.
Water vapor passes through while liquid water is repelled, so it won't peel or flake.
No gloss, no color change. Your concrete keeps its natural look and texture.

Not all concrete sealers are created equal. Here’s how our penetrating nanotechnology sealer compares to the alternatives most homeowners encounter.
| Feature | Our Nano Penetrating Sealer | Acrylic / Topical Sealer | Masonry Paint or Coating |
|---|---|---|---|
| How It Works | Bonds inside the concrete | Forms a film on the surface | Sits on top as a colored layer |
| Lifespan | 7–10 years | 1–3 years | Less than 1 year (exterior) |
| Changes Appearance | No — invisible finish | Adds gloss / wet look | Yes — colored coating |
| Breathable | Yes | Limited | No — traps moisture |
| Salt & Chloride Defense | Excellent | Moderate | Poor |
| Peels or Flakes? | No | Eventually | Yes |
Concrete waterproofing isn't just about keeping rain off the surface. Here's what a proper penetrating sealer defends against:
Our penetrating sealer works on virtually any porous cementitious or stone surface.
Not sure if your surface is a good fit? Send us a photo — we'll tell you straight.
We keep it simple, and we keep it clean.
We clean the surface down to bare concrete, removing dirt, efflorescence, old coatings, and contaminants that would block absorption. Any obvious cracks or repairs are addressed before sealing.
Once the surface is prepped, we apply our nanotechnology penetrating sealer at the manufacturer-specified coverage rate. It wicks into the pores and cures chemically — no topcoat, no sheen, no residue.
Typical turnaround: most residential jobs are completed in one day. Light foot traffic returns within a few hours; vehicle traffic returns in 24 hours.
No. Our penetrating sealer is invisible once cured — it doesn't add gloss, darken the surface, or change the texture. If you want a color change or a wet look, that's a job for a decorative sealer or concrete staining, not waterproofing.
Typically 7–10 years in residential applications, depending on traffic, sun exposure, and how aggressively the surface is cleaned. Because it bonds inside the concrete, it doesn't wear off like a topical coating.
The product is available, but results depend heavily on surface prep, coverage rate, and application timing. Under-applied sealer fails early; over-applied sealer pools and wastes product. Most DIY jobs we're called to re-do were surface-prep failures. See our guide on signs your concrete needs sealing if you're assessing condition first.
A penetrating sealer reduces water infiltration through the concrete matrix itself, but it doesn't fill or bridge active cracks. We identify cracks during the prep step and address them separately before sealing.
Pricing depends on square footage, surface condition, and prep required. Our concrete sealing cost guide breaks down what drives the number. Most residential driveways and patios fall in a predictable range — we'll quote you for free.
Yes. Ask us about our service warranty when you request a quote — it varies by surface and prep scope.
Protect your concrete before the next freeze-thaw season. We'll assess your surface, explain what it needs (and what it doesn't), and give you a straight quote.
