What Is Rip Rap?

Rip rap is a type of stone used to pile against slopes, especially in watery areas, to protect soil and structures from water erosion. They can vary in size and are unpolished; together, they break the force of water and protect whatever they are leaning against. 

Types of Rip Rap

Rip rap does not have to be one type of stone. It could be limestone, trap rock, granite, fieldrock, etc. This type of construction material also comes in three classes:

  • Class 1: Small stones of a 6-12 inch diameter
  • Class 2: Medium stones of a 12-24 inch diameter
  • Class 3: Large stones of a 24-30 inch diameter

Rip Rap Applications

Erosion can do a lot of damage to shorelines and the structures off of those shorelines. It can also whittle away foundations of constructions in the water. Water is constantly moving, and that’s a healthy thing. However, the constant waves and currents and freeze-thaw cycles take a toll on whatever it hits. For this reason, rip rap applications include:

  • Slope stabilization: Erosion control for the shorelines of lakes, rivers, and other beaches or steep slopes
  • Protection for bridges, culverts, abutments, etc.: Erosion control for the bases of bridges and other man-made structures

Reliable Rip Rap

Rip rap is beneficial for its longevity and affordability. These stones, once installed, can last in place for up to a century in good condition. Rocks can withstand the test of time, and plenty have already been around for centuries before they were used for rip rap.

It is also relatively affordable, compared to other erosion control options, and requires little maintenance.
