Any reason not to do this filled with crushed marble along side my house? We have tons of marble chips and have decided to consolidate all of them to one side of our house. Wife and I like this look to contain them but I’m a little concerned about drainage as it’s the side of our house that tends to collect water. How would I do this or something similar with drainage in mind? Originally by u/PissJohnson1 on Reddit: https://tinyurl.com/24tfzpxk
