Platon Membrane


Platon Membrane

For Protection of Basements/ Below Grade Areas / Retaining Walls




Platon is a rugged, double- dimpled high-density polyethylene (HDPE) membrane that keeps foundations, cellars and retaining walls dry.   Platon creates an impermeable barrier and air gap, allowing concrete to breathe whilst controlling moisture.

Platon keeps wet soil / backfill away from the wall.  Any moisture that may find its way past the membrane is carried to the footing drain by the air gap drainage path. This dries out the wall in a way that no other technology can match.

Because the membrane is only fixed to the wall at the top, the wall can crack, shift and settle over the years without affecting Platon’s remarkable performance.

Platon is commonly used to waterproof Block Walls, Poured Concrete Walls , existing foundations and Insulated Concrete Forms (ICF).

It can be used for retaining walls, built-up flower beds, cellars, culverts and many other applications.
