Class B: This type of gravel typically consists of larger stones, ranging from 5 inches up to 12 inches in size. It is commonly used on slopes to assist with erosion control or placed in ditches to facilitate water flow. Rip Rap, known for its stability, remains securely in place even during periods of high water flow. It is frequently found on embankments alongside roads and within drainage ditches. The Rip Rap stones are available in both lighter and darker shades of blue-grey, providing a natural and durable solution for erosion prevention.
