Hello, need help and support! I'm planning to make a driveway to our property but I'm a bit unsure about what material to use! I'm considering a culvert about 300mm in diameter and 6000mm long! One thought is to dig it out to have a nice slope, lay down geotextile fabric, fine gravel at the bottom and around the culvert, and sub-base up to the same level as the road! Of course, watering and compacting between layers! Does this sound like a sustainable solution?
