Riprap stone refers to rock that has been initially crushed and then screened. This type of gravel is extremely rugged, and does not get washed away or immersed in the soil easily. As a result, it is often used in construction or for commercial applications.
Riprap stone sizes vary from between four to nine inches, and the one chosen can largely depend on the purpose of the stone. Before getting started with your project, read this guide to riprap stone sizes to properly choose the size for your project.
4″ or 5″ Riprap Stone Uses
This riprap stone size is ideal for bases. Whether you’re creating a base for a driveway or gravel parking lot, this small stone size is exactly what you need. That’s because they are durable enough to withstand a great deal of wear, yet won’t be extremely bumpy to drive on.
Since riprap is also ideal for preventing erosion, this type of rock might be used near ditches. That way, it can not only keep soil from eroding, but aid with weed control as well. Small riprap stones could also be ideal for walking trails or placing around the base of a tree.
6″ to 9″ Riprap Stone Uses
Medium riprap stone sizes are ideal for preventing erosion along the shores of lakes, rivers and streams. This stone is not ideal for walking on and can be used to deter people from going to specific areas. This means you could easily put it near a dangerous section of a shoreline, even if that area is not plagued by erosion.
This size of rock is sometimes used along railroad tracks or on gravel roads that are traveled on by the public. Stones in this size range can also be good choices for creating a retaining wall. It could be placed inside a wire cage at the base of an incline in order to stabilize the earth and allow for good water drainage.
9″ Riprap Stone Uses
The largest riprap stone sizes are more useful at preventing erosion than small or medium-sized rocks are. As a result, they may be used in areas where extensive erosion could occur.
They are often placed on the sides of hills for this very reason. Large riprap stones can also be used in drainage ditches or to restore banks that have been partially washed away. This stone could also be ideal for filling in very large holes or ditches.
This variety of riprap stone sizes are all available for bulk delivery. Since it can be difficult to determine how much material you might need, it can be a good idea to get an estimate from a reputable contractor before ordering to ensure you receive an adequate quantity.
