Riprap Rock

More Than Just A Pile Of Rocks

Rock Slope Protection (RSP) is among various bank and shore protection materials and methods. RSP, also called riprap rock or riprap, consists of one or more layers of rock; it is placed along river and stream banks, or along ocean and lake shores to prevent erosion. 

This is a commonly used method to protect soil from erosion in areas of concentrated runoff. Riprap is a layer of very large stones interlocked together acting as a barrier on slopes that are unstable because of seepage problems or areas that are receiving a large concentrated flow.

Uses For Riprap Rock Include:

Erosion can compromise bridges, wash out adjacent roadways, or cause loss of property; preventing erosion helps to keep the public safe. At first glance, riprap may seem like a simple science for mitigating the power of water, but it requires a lot of evaluation from engineers. 

Ripraps can be used to stabilize cut and fill slopes preventing erosion and other stabilization problems. Riprap, is extremely useful in a number of different construction applications such as:

  • Channel Sides and Slopes
  • Culverts inlets and outlets
