If the area is exceptionally soft, placing a layer of geotextile down first will help bridge the material and keep the softer substrate material from coming up through into the granular layer. We recommend placing 2” minus over the geotextile. 4” minus is also a recommended product for this application, however we find the 2” minus does a comparable job and is easier to grade and work with. As well, 2” minus offers a better temporary driving surface over 4” minus.
