Polyguard Stretch Flex is a solvent-based, elastomeric coating which cures to form a durable waterproofing membrane capable of bridging cracks up to 1/16th of an inch. Polyguard Stretch Flex is designed for waterproofing below-grade concrete, precast concrete, CMU and other vertical foundation surfaces where hydrostatic pressure may be present. When used with Polyflow 10 and Blue Barrier Joint Filler 2200 compatible sealant, Polyguard Stretch Flex provides a complete foundation wall waterproofing system.

It is NOT designed for above-grade applications, horizontal substrate applications such as decks, patios and roofs, nor for use as waterproofing over ICF (Insulated Concrete Forming) systems. (Please see our Home Stretch Membrane sheet waterproofing system for ICF foundation wall waterproofing).
