AlphaGuard BIO

⠀UV Resistant, Two-Part, Bio-Based, High Performance Polyurethane Waterproof System

AlphaGuard BIO is an extremely high performing composite waterproofing system, designed with a focus on roofing restoration. AlphaGuard BIO has the ability to be installed over various existing roofing membranes in order to minimise tenant disruption and extend the life of the roof for an additional 20 years. It cures to form a durable rubber membrane surface that provides a lasting and easy-to-clean waterproof coating. AlphaGuard BIO may be used to apply a seamless, monolithic waterproof membrane to concrete, primed metal, or existing roofing membrane surfaces.
