We recently had a patio poured for our hot tub. It required that the yard be excavated about 8 inches at it's highest point. I have some edgers that I laid out (layed out?) and was wondering if it would be okay to use them as a mini retaining wall. If I can use them, is there anything special I need to do besides placing them and making sure they are level? I will need to do two layers to cover the 8 inches - which means there is a potential for the top layer to slide off. Anything I can do to prevent this?Thank you! via /r/DIY http://ift.tt/2qKi5Ys
