The layer between the gravel and concrete slab
Today, they applied a layer to the top of the gravel. Ultimately, this layer (shown in white, above) will be between the 6 inches of gravel and the 18 inches of concrete. It's about 1/8 inch thick and is supposed to bond to the concrete to create a water-proof barrier. They didn't finish today so they'll finish up tomorrow.
