In our 62 years of specializing in Corrosion Coatings, and 42 years in commercial waterproofing, Polyguard has evolved into a Single Source manufacturer of Integrated Building Envelope materials.

This includes:

Waterproofing: Polyguard’s below grade waterproofing product line includes membranes intended for both pre-applied and post-applied applications and includes both sheet and fluid applied products. Concrete slabs and foundation walls almost inevitably crack, providing entry to water and contaminates. Our products are designed to stand up to the harshest of conditions and have been proven through over 30 years of use..

Air Barriers: Air Barrier Systems provide the only effective defense against air leakage and, more importantly, moisture issues. According to the Department of Energy, up to 40% of the energy used to heat or cool a building is lost to air that is then leaked into or out of a building. Polyguard has designed and introduced to the market a variety of both permeable and impermeable as well as water-based and solvent based products to meet virtually any job site and environmental condition. The Airlok Flex® brand of fluid-applied products consistently outperform other products on the market, helping to improve energy efficiency and sustainable construction. Our products have been tested and passed NFPA 285 testing protocols and can be designed into a variety of assemblies.

Wall Systems: Have you heard the old saying “The devil is in the details?” Nothing can be more true when designing or installing Air Barrier and Waterproofing products and systems. The time spent in detailing a project typically is critical to the success of a project. Polyguard Architectural Products manufactures and markets a series of Through Wall Flashing and Accessories to connect, divert, and drain moisture out of your wall system. They come in various thicknesses (30 to 105 Mil), different widths (4 to 36 Inches) and various lengths (33.3 to 100 Feet) each designed and engineered to meet a specific need that you may encounter on your next project.

Drainage: The Polyflow® Drainage family of products were designed and introduced by Polyguard Architectural Products to provide our customers a variety of solutions to lightweight drainage and at the same time be compatible with our engineered sheet and liquid membrane products. These products are lightweight, have high capacity, can decrease excavation needs and are easy to install. We offer 10,000, 15,000 and 18,000 psf products. Some of our products are to be installed vertically, some horizontally. Some products come with a high strength Polymeric film on one side and some without. Whether it is called “Drainage Board”, “Dimple Board”, or “Drainage Panel” we have below grade drainage products to compliment your waterproofing system. For high volume applications see our Polyguard Total Flow product and accessories.

Specialty Barriers: Polyguard also has specialty barriers, including:

Waterproofing and Radon Barrier tested against radioactive radon.
Waterproofing and Methane Barrier  where methane gas is a concern.
Waterproofing and Contaminant Barrier for brownfield applications.
