Need shelves up in my basement. Concrete walls. I do not want to drill holes as I have a warranty on the foundation and would require someone to come out and make sure it wouldn't compromise the warranty.The idea is to use mounting tape which can hold up to 30 pounds on L brackets. And place a shelf board on top of it. The shelf will be holding D&D miniatures and crafting materials. via /r/DIY https://ift.tt/2xwmWyC
