QUESTIONS:
What can your product do to help keep this from becoming a bigger problem?
Answer:
Our SealGreen Concrete Sealer will mitigate three things that happen when the concrete is contaminated with Lignite.
1. The holes that already pop if not treated with a sealer, will continue to expand every winter. Our SealGreen Concrete Sealer will not fill the holes, but it will seal the interior and the edges of the hole and prevent winter expansion effects.
2. You can tell where the holes that have been affected by the winter but have not pop yet. Usually there is a fracture hairline size in a circle around the hole that with time will open leaving a hole. Like the ones you see today. You cannot stop the damage now.
3. If you seal all the concrete with SealGreen Concrete Sealer you will prevent water penetration into the concrete. A seal concrete prevents the water reaching whatever lignite is in the concrete and during winter freeze it will prevent the lignite from expanding and creating holes.
Can I, as a homeowner, purchase your product and apply it myself to the damaged areas?
Answer:
Yes, you can do the application yourself please watch the following video -
. You can buy it online at SealGreen Concrete Sealer or call us and place your order at 800-997-3873. To place an order, you will need to know how many square feet of concrete driveway you have. Can you offer any other suggestions? Answer: We recommend SealGreen Concrete Sealer because it is a penetrating chemically reactive sealer. SealGreen Sealer penetrates the concrete up to one-fourth-inch depth. Reaching most of the Lignite. Because lignite is light in weight it will be located near the surface of the concrete. Therefore, the SealGreen Sealer does an excellent job in sealing it and prevents freeze expansion. Our original contractor wants to use something called Ardex 100(I think)? I am not sure of the name. I saw your product and did some research and am intrigued with the technology and how it might help us. Answer: Ardex is a company that makes a large variety of exceptionally good cementitious materials. Unless you have many holes in the concrete I would recommend not trying to fill them all because it makes the concrete look repaired. Especially if your concrete is new. We have used Ardex to repair a large area of new concrete and initially it matches the new concrete color but over time the patch of Ardex did not change color like the rest of the concrete and it became obvious the difference between patch concrete and the rest of the concrete. If you decide to use Ardex you will still have to seal the entire driveway to prevent future pops.
