I need to install a culvert pipe across the drive. We are getting rain and there is one spot that keeps flooding. Im going to dig up the drive and install a corrugated metal pipe like in the picture. Do any of you have a calculation or rule of thumb as to how far it should be buried under the drive surface. At times the traffic over the pipe will be heavy. Is this type of pipe pretty tough? One side will be shallow to collect the water the other goes into a pasture land that is about 4 ft lower. Thanks for any thoughts on this ive never worked with any of this. The pic is kind of what im after.
