A bag filled with small rocks works similarly to one large rock but more effectively. Bluemont Rock Bags™ placed on the site act as a barrier, preventing the water from washing away the soil or sand. The gaps between the small rocks also promote the growth of plant and marine life, strengthening the erosion control system further.
Yes. Bluemont Rock Bags™ are ideal for use in both freshwater and seawater environments.
As Bluemont Rock Bags™ are flexible in structure, they are suitable for many applications. You can use them for erosion control and prevention in ports and coastal areas, railways, bridges, waterways, roads, offshore and subsea.
