Keeping basements dry is a one-membrane job.


Platon is a waterproofing membrane that works with our Form-A-Drain® system to keep basements warm and dry.

Its unique, double-dimpled design separates water from the foundation wall and permanently bridges foundation cracks, preventing moisture from entering the basement of a home. Platon works with all kinds of foundations—from block and poured concrete walls to insulated concrete forms. A durable, high-density polyethylene [HDPE] membrane keeps wet soil and foundation walls apart with an air gap that lets air flow and moisture drain.

There’s no need for other waterproofing treatments, and Platon can be installed under all weather conditions—without a special crew or equipment. Speedclip and Speedstrip fasteners keep installation simple.
