The Mirafi 1100-series is an extra-heavy nonwoven line for the toughest separation and stabilization demands.

These high-mass needle-punched polypropylene fabrics offer maximum puncture, tear, and burst resistance while continuing to drain and filter. They are built for heavy riprap bedding, severe subgrade stabilization, and high-survivability separation under extreme construction stress.

Reserved for the most demanding installations, the 1100-series handles the sharp aggregate, heavy equipment, and difficult soils that would compromise lighter fabrics, protecting the structure for decades.
