Advice for building patio - have an unorthodox idea
Hello fellow DIYers. I have a small urban enclosed backyard, roughly a 12x15 patio surrounded by raised gardens on three sides. Right not it is just a bunch of broken bluestone flagstones sitting on dirt. It is very uneven, very uncomfortable, and in some spots a tripping hazard. I want to replace it with a smooth, level patio. But I want it to be fairly permeable - no mortar. Before we moved to this house, I built a patio the normal way - several inches of sand/gravel mix, tamped, and pavers on top with sand brushed over it. In that case I put polypropylene PaverBase under the pavers for stability. It all came out very nicely. This time I’m thinking about something more radical, for purposes of handling water. (We get occasional big storms that can dump 4-8 inches in a couple hours.) I’m thinking: - Dig down ~5 inches. The soil has a fair amount of clay down there. - 2 inch high gravel grid, filled with gravel - Paver Base tiles on top of that - Pavers on top - Around the sides, by the gardens, about a foot width of gravel instead of pavers. Can use some stakes/hard edging to keep the pavers steady in the middle. The idea is, by having gravel in grids underneath the pavers instead of sand, it becomes like a large, shallow dry well. Those 2 inches would hold 30+ cubic feet of water! So: talk me down. Is this crazy? What have I not considered? submitted by /u/DumbScotus [link] [comments]
