Enter the area you need to cover and pick a stone class to find tons of rip rap needed for embankment or drainage erosion control.
Estimate only — check your erosion control plan for the required stone class and layer thickness.
Each stone class has a recommended layer thickness — larger stone needs a thicker layer to interlock properly. We convert your area and that thickness into cubic yards, then multiply by rip rap's typical density of about 1.5 tons per cubic yard.
It depends on water flow velocity and embankment slope — Class 1 suits low-flow ditches, Class 2 handles moderate flow like most residential drainage, and Class 3 is for higher-energy areas like stream banks. A site-specific erosion control plan can confirm the right class.
Usually yes — geotextile fabric under the stone keeps soil from washing up through the gaps, which extends the life of the erosion control installation significantly.
