A contractor places Riprap at the part of an Illinois project where water meets unprotected ground. Flat prairie clay can drain slowly, and northern freeze-thaw conditions can leave a bank, slope, or drainage route exposed to erosion. The material is suited to stream banks, shorelines, drainage channels, and areas below culverts that need a heavy stone armor against moving water.
Keep Riprap focused on the flow path instead of using it as routine surfacing across a drive or pad. Smaller aggregate can be carried off in a location receiving concentrated water, while Riprap is intended to protect the soil beneath a water-exposed surface. This approach applies along the Illinois River and Mississippi River, through the Fox Valley, and on drainage work near farm lanes. If the work requires smaller erosion-control stone or a heavy base layer, review the crushed stone choice for that job rather than substituting Riprap.
