Maccaferri Gabion Mattresses are used for permanent erosion control in channels, stream banks, spillways and stable slopes from surficial erosion. The stone confinement within the units allows for higher shear stress resistance than riprap. Made of PVC coated galvanized wire, gabion mattresses are divided into compartments and filled with stones at the project site. With lids closed, the gabion mattresses form flexible, permeable, monolithic structures. Considered a robust alternative to rip-rap, gabion mattresses offer long term performance against aggressive flow conditions and do not rely on vegetation for their hydraulic performance. The 100 ft (30 m) long units make installation fast and cost effective.

Advantages of Maccaferri Gabion Mattresses:

• Gabion mattress strength lies in the double twisted hexagonal steel wire mesh, which is reinforced by selvedges of heavier wire running along the edges
• The base section is divided into compartments to restrict the movement of stone and strengthen the structure
• The lid is supplied as a separate panel
• The wire will not unravel even when cut
• Easily assembled, requiring no specialized labor and using nearby rock for fill
• Free drainage and 30-35% voids allow vegetation to grow
