  • Waterproof containment can be created using a plastic membrane/liner (HDPE or EPDM are common materials).
    • When the membrane is being used directly in the ground, punctures from stones can be prevented by compacting a layer sand (30 - 50 mm) over the soil prior to installing the membrane.
    • Similarly, a 50 mm sand layer should be applied on top of the membrane to protect it from the clear stone being used for drainage inside the BMP.
