The Mirafi G-series is a prefabricated drainage composite that relieves water pressure behind walls and structures.

It combines a high-flow drainage core with a bonded nonwoven geotextile, collecting water and carrying it away while filtering out soil. This reduces hydrostatic pressure against retaining walls, foundations, and below-grade surfaces.

The G-series replaces traditional aggregate drainage layers with a thin, easy-to-install sheet, saving space and labor while providing reliable long-term subsurface drainage.
