Platon® Waterproofing Membrane

Platon® is made from tough, durable, high-density polyethylene (HDPE), Platon is a waterproofing membrane that provides superior moisture protection for all types of foundations in residential basement applications. This dimpled 24-mil. wrap separates water from the foundation wall and permanently bridges foundation cracks, preventing moisture from entering the basement of a home.

Platon can be installed under all weather conditions, and does not require a special crew or equipment. Installation is fast and easy thanks to Platon Speedclip and Speedstrip Fasteners.

Use Platon in conjunction with Form-A-Drain to keep basements dry and healthy.

Platon can also be installed over existing basement floors to isolate floors from cold damp concrete, keeping basements healthy, warm and dry.

Platon Foundation Waterproofing System
I ordered this membrane to go over the delta. The homeowners that hired me had severe damage to the exterior due to a previous contractors negligence. This system once installed made a total difference. No more water in basement. Install time was super quick and easy. Will definitely be purchasing more to keep in stock.
