2"–8" riprap
What is riprap?
Riprap is large, angular rock ranging from about 2" to 8". The sharp edges lock the pieces together, so it stays in place and shields the soil underneath from moving water.
It's used to armor ditches, culvert ends, creek banks and steep slopes, anywhere water is trying to wash the ground away. It also compacts into an extreme-duty road base, which makes it a great choice for really soft, muddy areas with poor soil conditions.

Riprap questions
Most pieces range from about 2" up to 8" across, with a mix of sizes in between. Depending on the quarry, you may see some pieces that are a little larger.
Riprap is used for erosion control along ditches, slopes, culverts and creek banks. It also compacts into an extreme-duty road base for really soft, muddy areas with poor soil conditions.
It's a good idea in most cases. Landscape or filter fabric underneath keeps the soil from washing out between the rocks, which helps the riprap stay in place longer.
Riprap is angular, so the pieces lock together and stay put on slopes and in moving water. Cobble is naturally rounded river rock, which looks great in landscaping but can roll and shift more easily.
