- Large, heavy stone
On an Iowa job, Riprap belongs where drainage leaves a tile route, reaches a bank, or crosses an exposed slope. Deep frost and repeated thawing can leave soil vulnerable when water concentrates along a defined path. This material provides the heavy stone cover needed at shorelines, stream banks, drainage routes, and areas below culverts where erosion control is the purpose.
Plan the protected area around the actual water path instead of treating Riprap as general driveway stone. It is intended for locations where moving water could carry lighter aggregate away. That makes it a practical choice near the Mississippi River, the Missouri River, the Des Moines River, and acreage drainage work where runoff has a direct route across bare ground. For a job needing smaller erosion-control stone or a heavy base layer, compare the appropriate crushed stone option.
