Filter Fabric Jackets

FDOT compliant strap-secured jackets for pipe joints


Simply Wrap & Lock

MarMac Filter Fabric Jackets use specially engineered high-strength fabric that allows water to pass freely through the joint, when acceptable, while preventing the passage of silt and soil. Standard filter fabric jackets are designed and manufactured for civil engineering applications and to meet DOT specifications. Jackets are also available in woven and non-woven fabric often specified for subsurface drainage and filtration.
