MIRAFI® G-Series drainage composites are made from high compressive strength cores and combined with nonwoven filter fabrics to provide clog resistance and long-term flow capacity. These products are ideal single-sided subsurface filters and are used to provide a consistent drainage medium for retaining walls, cut-off drains, and landfill closures.

Key points:

  • bullet point

    Multi-directional core configuration provides a uniform flow path for water to escape, enabling consistent and proven long-term performance.

  • bullet point

    Relieves hydrostatic pressure buildup against subterranean surfaces.

  • bullet point

    Provides high-flow drainage capacity of up to three times the flow capacity of aggregate or sand.

  • bullet point

    Designed with a high compressive strength core to withstand installation and in-situ earth stresses.

  • bullet point

    Easy installation provides significant cost savings.
