I'm about to cover the overflow pipe in my pond with concrete to ballast it down. So how much buoyancy does that pipe have? how much concrete will I need? The pipe is 6" HDPE corrugated and the O.D. is 7"... To save you the guys I created a table showing the buoyancy per foot of common pipe sizes. I'm using concrete by the bag, but if you want to use soil count on 130 lbs per cubic foot of cover in your ditch. I've also included a chart to show how deep a ditch should be to satisfy this requirement.
