Polyfond Kit Drain is a high-density polyethylene (HDPE) protection and drainage sheet laminated with a polypropylene nonwoven geotextile. It provides both mechanical protection for waterproofing membranes and reliable vertical and horizontal drainage in below-grade applications.

Builders are increasingly moving away from Corflute sheets alone behind retaining walls. While Corflute offers basic protection, it provides no real drainage. The new standard is engineered drainage cell systems like Polyfond Kit Drain — designed to create a void, channel water efficiently, and relieve hydrostatic pressure for long-term performance and structural integrity.

Ideal for retaining walls, basements, and foundation systems, Polyfond Kit Drain prevents hydrostatic pressure build-up while protecting waterproofing layers from backfill damage. Its dimpled HDPE core and geotextile facing ensure effective filtration, ventilation, and lasting waterproofing protection.
