Riprap, shot rock, rock armor, or rubble. Rip rap has many names but it all refers to one material, loose stone. These large, loose stones or concrete chunks are used along shorelines, streambeds, abutments, embankments, pilings and other structures along shorelines and waterways. In all these uses, rip rap serves as an effective protective barrier against erosion cased by water, waves and ice.
Fighting Erosion with Riprap
Erosion is a serious threat to bridges, shorelines and any structure exposed to rushing water. Around lake shorelines, rip rap reduces erosion from waves. Along river ways, especially at river bends, riprap protects the river banks from the force of the water.
The effects of erosion are also felt my man-made structures. Bridge abutments, pilings and embankments will deteriorate overtime if not protected from erosion. While riprap may seem like a simplistic solution, engineers evaluate sites extensively to determine the most effect use and placement to mitigate the effects of erosion.
Riprap and the Environment
Rip rap can be composed of natural rock but it is also commonly comprised of recycled concrete. Using large chunks of broken concrete, riprap gives this used material a second life.
The use of riprap creates a natural-looking barrier to defend against erosion. This can help keep developing areas preserve a more natural look and feel. This nature-friendly look can be taken one step further. Adding smaller rocks and soil to larger open spaces makes the rocky material easier for animals to traverse.
