Urbanite - A New Mineral?

Even if you were paying really good attention in your Geology 101 class, you probably haven’t heard of urbanite. It comes in almost any color you can imagine, sits conveniently on the earth’s surface waiting to be loaded on a truck, and is as hard as concrete.

That’s cuz it IS concrete—recycled slabs of pavement seeking a second career. It makes sense to put such a durable and multi-use material back to work, instead of dumping it into landfills, then mining and manufacturing more.

Urbanite has lots of uses in the garden, as I was reminded on my Open Days garden tour in Pasadena last month. If you can build something with flagstone, you can generally substitute urbanite at a much reduced cost. It’s free, since scrap concrete is usually seen as a waste product that has to be disposed of. Most of the expense is in short-distance transportation and labor for installation. Better yet, if the concrete is from your former cracked driveway or patio, you can even scratch the cost of loading and transport.
