I watched your show about the renovation of the house in Pheonix. They did the yard to resemble the desert surface which I believe was crushed Granit. There was a material tilled into the gravel. What is it and will it work on pea gravel. I have considered just tilling in premix concrete and raking it smooth, then watering it. Sorry, I misled you. This is for pathways I have throughout my back yard. I want something that is pretty durable.
