Why Concrete Driveway Sealing

Protect your new concrete driveway from oil, water, salt, stains & moisture for up to 10 years! !

When I moved into my new home, my concrete driveway caught my attention. I wondered why it was concrete and not traditional asphalt. What if oil or trash stains ruined its pristine look? And would snowy days cause salt damage?

Digging into it, I discovered concrete driveways were trendy but lacked protection – no sealing meant vulnerability to stains and salt damage. Maintenance was crucial, and cracks were a real headache.

As devoted problem-solvers, we expanded our expertise in concrete driveway solutions, striving not only to the most durable options, but also to deliver a service that exceeds their expectations designed with four indispensable criteria in mind:

Longevity – No more yearly resealing; our product stands the test of time.

Protection – Shield your driveway from stains and salt damage, worry-free.

Compatibility – Keep your driveway’s appearance intact and HOA-compliant.

Affordability – Invest for the long term, no yearly reapplications, more savings.

Consumer Grade VS Professional Sealing

The main difference between consumer-grade and professional-grade sealing lies in their Composition: While sealers sold at the big box store will contain 5-20% active ingredients only, professional sealers formulated with higher concentrations of active ingredients, can range from 40-100%. This offers enhanced protection and longer service life, reducing the need for frequent reapplications.


Benefits of Concrete Driveway Sealing


Resists oil, water and salt

  • Excellent waterproofing – Penetrates deep within the concrete chemically reacting within the pores and capillaries creating a long-lasting hydrophobic surface that beads water.
  • Resists staining from oil and grease – Oleophobic fluorocarbon makes oil and grease easier to clean from treated surfaces decreasing maintenance requirements

Reduces Moisture Intrusion

  • Reduces moisture intrusion – Resists wind-driven rain, prevents freeze-thaw damage, spalling, pitting and cracking.
  • Resists atmospheric staining – Resists mold, mildew, lichen, efflorescence and dirt pick up.
  • 100% breathable – Non-film forming. Allows moisture within the concrete to escape without adverse effects to the sealer. Does not trap moisture

Improves Durability

Sealing your concrete not only protects it, but also helps it last longer. It’s worth mentioning that sealing is a cost-effective and straightforward process when compared to the expense of replacing a concrete surface.

  • Improves durability – Prevents capillary uptake of water and the aggressive substances dissolved in it. 
  • Natural flat finish – Does not change surface appearance, UV stable will not breakdown with light exposure and HOA friendly.
