We’ve all seen PolyLevel videos on YouTube: heavy sunken concrete driveway slabs moving back up to their original position as if lifted by some supernatural force. It’s fun and fascinating to watch:
So, what’s the catch? Is it expensive? No, not particularly. Is it rare? Actually, we are an exclusive dealer!
Aha! It’s probably bad for the environment, right?
How PolyLevel Interacts With the Environment
PolyLevel foam is a lightweight, durable and, above all, amazingly strong high-density polyurethane foam. The reason it works so well is, it runs like water when first injected under concrete, finding even the smallest crevices. But then it quickly expands, and the force of that expansion is enough to lift those heavy concrete slabs back to their original positions. And, when PolyLevel cures, it cures basically forever.
High-density polyurethane foams such as PolyLevel have been the subject of several studies over the years, including one conducted by the Department of Energy (DOE), and they’ve found a couple of interesting things:
PolyLevel is a non-ozone depleting two-part polyurethane foam that is chemically inert once it cures. That means, once it sets, it does not react with anything around it, so it won’t leach into the soil or otherwise impart chemicals into the environment.
PolyLevel does not biodegrade. This means it doesn’t break down over time and affect the environment around it. It is also highly resistant to microbial attack due to its chemical and physical structure.
PolyLevel provides no nutritional value, and as such, it is not likely to be broken down by animals or insects.
While polyurethanes can degrade over time when exposed to UV radiation, because PolyLevel is never exposed to sunlight, this is not an issue.
Basically, once it cures, PolyLevel is no different, from an environmental point of view, than the concrete it stabilizes.
PolyLevel Helps Reduce Waste and Pollution
One of the best things about PolyLevel, though, is that it helps keep tons of concrete out of our landfills — literally. Think about it; if your driveway is cracked and sunken, your two main options are to repair or replace it. PolyLevel offers a fantastic solution for the first option. But when you replace a driveway (or any concrete), you not only have to wait a week or more for it to cure, but all that old concrete must be jackhammered into smaller pieces, torn out and hauled off to the local landfill, where it will remain for pretty much the rest of time.
Then there’s the problem of new concrete. Did you know that, after water, concrete is the most consumed material on the planet? And, concrete production is the source of a huge amount of greenhouse gasses, which are a primary driver of climate change. Then there’s the damage to the environment caused by mining the raw materials that make it up.
When you repair your driveway, sidewalk or patio with PolyLevel, you’re not only keeping old, broken concrete out of the landfill, you’re also reducing the need for new concrete to be produced. And that’s a good thing for the entire planet.
In the end, PolyLevel allows you to lift and permanently stabilize your concrete while helping reduce waste and pollution. See? No catch!
