The eco-friendly Burlap Bag is a perfect aggregate bag for more environmentally sensitive projects. The bag itself is made from naturally grown jute fibers and is 100% biodegradable. These naturally tough, woven bags can be used for a variety of sediment and erosion control purposes and can be filled with any of our standard aggregate choices – ⅜” pea gravel, 5/16” bird’s eye gravel, or sand.
