Polar Fold® Protection board

Protecting a foundation from backfill is crucial to the integrity of sheet membrane or liquid-applied waterproofing, because aggregates in the backfill can puncture the membrane and reduce the effectiveness of the waterproofing. Polar Fold® is strong, yet lightweight, making it the ideal protection board for below-grade applications. Polar Fold®expanded polystyrene (EPS) is not affected by chemicals or moisture and it can serve as an insulation when the project requires below-grade insulation.

Polar Fold® is manufactured with a rigid EPS insulation core wrapped with tough film facers and is used for protection in both vertical and horizontal applications. Higher R-Values can be achieved by specifying Polar-R®.

Polar Fold® EPS is available in 4’ x 50’ sheets and comes in 3/8” and 1/2” thicknesses.

Installation Instructions for Polar Fold® Protection Board

Polar Fold® EPS is compatible with various sheet and liquid-applied waterproofing. Consult the waterproofing manufacturer for specific details. Polar Fold® should be applied on a vertical surface with an adhesive that is compatible with EPS insulation. Care should be taken to tightly butt all protection board joints. Prior to backfill, all material needs to be inspected to insure that all waterproofing is properly protected before proceeding with backfill. Consult waterproofing manufacturer for specific instructions. Horizontal surfaces can be protected with Polar Fold®Protection Board. All material needs to be laid loosely and all joints should be tightly butted prior to finishing.
