Fanwall^® permanent barriers are available for nearly every noise or security problem. A unique, rotatable and interlocking connection system makes Fanwall freestanding precast barrier extremely versatile. Barriers can be erected completely on-grade with minimal ground preparation. Where site restrictions limit the trapezoidal layout of a freestanding Fanwall barrier, a Fanwall post and panel system can be installed. This alternative has fewer post sections and foundations than conventional systems. Fanwall provides a low cost, effective and aesthetically pleasing permanent barrier solution for transportation, utility, industrial and commercial applications.
