The Complete Riprap Stone Sizes Guide
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 for the stone. Read this guide to riprap stone sizes to find out which size is best for your project.
4″ or 5″ Riprap Stone Uses
Smaller riprap stone sizes can be ideal for creating a base for a driveway or gravel parking lot. 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. The fact that this stone is also somewhat difficult to walk on makes it an excellent choice to use in areas where you might want to deter people from going. 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.
All of the different riprap stone sizes are 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.
