Two layers of poly sheeting?
Would it be okay to put two layers of poly under a basement slab? The layers would consist of 4" of gravel, one layer of poly sheeting, one layer of XPS foam board, another layer of poly sheeting, and then the concrete slab.
Would this be beneficial or would it be overkill? I am building in central KY if that has any implications. Thanks for any input.
