Westcoat is proud to announce that the ALX Pro Waterproof Walking Deck System, in both Standard and Custom finishes, has been independently tested to meet the industry standard, International Code Council (ICC) Acceptance Criteria for Walking Decks (AC39) and has received waterproof deck certifications through the ICC’s recognized evaluation service ICC-ES. It joins ALX Standard and Custom on the updated ICC-ES Evaluation Report ESR-2201 available on our website.

All Westcoat ALX and ALX Pro systems provide a Class A Roof Covering Classification (ASTM E108) and One-Hour Fire Rating (ASTM E119). In addition to these certifications, when WP-40 Sheet Membrane is applied over the entire plywood substrate, both ALX and ALX Pro in Standard and Custom finishes meet classification for a Class I Vapor Retarder (ASTM E96) and have been certified by ICC-ES (ESL-1106, ESL-1098). These waterproof deck certifications can be viewed from our ALX system page.

What is ALX Pro? 
The ALX Pro waterproof walking deck system features all the proven attributes and benefits of the existing ALX system, but features an additional Fiberlath Resin Membrane layer. This additional layer provides greater waterproofing and helps protect against cracking, especially on larger spans or cantilever decks. This system gives plywood the look and feel of concrete with a decorative appeal. ALX Pro has been designed for balconies, corridors and landings. It is regularly specified for hotels, condominiums, apartments and office buildings. ALX Pro can be stapled through most old deck systems to provide an excellent method for the rehabilitation of problem surfaces.

ALX is the clear choice when choosing a waterproofing system. It is regularly specified for hotels, condominiums, apartments and office buildings. It is recommended for the discriminating architect, contractor or building owner that demands the greatest in strength and durability. When installed by a Westcoat QCA, this system is eligible for up to a 15-year warranty.
