Air Gap Waterproof Membrane


Keep it dry


Platon is a uniquely dimpled, 24-mil high density polyethylene membrane, performance proven since 1991 to prevent basement leakage problems.

Platon features:

  • Double leakage protection (Holds wet soil away from the wall and provides drainage)
  • Allows the wall to dry
  • Easily bridges I/4" cracks
  • Keeps working even if the wall cracks or shifts
  • Works on any type of foundation, old or new, regardless of wall condition
  • Installs in any kind of weather
  • Double Dimple design provides a smooth, low drag, soil side surface
  • Easily installed with concrete nails (use screws on ICF foundations)
  • No other wall treatment is required
  • Excellent protection board for other types of waterproofing (Triple leakage protection)
  • 30 Year Manufacturers Limited Product Leakage Warranty (Foundation use)


Environmentally Responsible:

  • High recycled content (92%)
  • Chemically Inert - No by-products contaminate soil or air
  • All manufacturing waste is recycled

It is imperative, as with all waterproofing systems, that foundation drainage, like Form-A-Drain or traditional drain tile is in place and functioning properly to ensure that water and moisture drained by Platon can be removed.
