F E B R U A R Y 2 0 2 0 | 13 Restoration Products & Services VP of marketing for Demilec, notes that the closed cell spray foam insulation from her company pro- vides not only superior insulation properties but also acts as a barrier to water – to the degree that FEMA recommends its usage in structures in high- risk areas and some insurance companies (mainly in the U.S. eastern seaboard) offer discounts if it is installed in homes. Demilec's Heatlok and Polar Foam brands of closed-cell can be installed anywhere, and the prod- uct range provides outstanding high-performance options for commercial, residential, and agricul- tural projects. "We also have an ultra-low global warming product, which is important as our HFO product will begin replacing the old HFC foams in the coming year," says Cosper. Les Faure, advertising and promotion director for Xypex Chemical Corporation, reports that his company has been involved in a wide variety of res- toration projects in North America, with the many notables including the Gateway Arch Expansion in St. Louis. The Gateway Arch project is significant because Western Specialty Contractors (WSC) used Xypex Concentrate and Modified crystalline treatments to waterproof nearly 20,000 square feet of interior tun- nel surfaces. "We would apply the Xypex for three or four days and then take a short break while other workers finished their jobs," says Thom Belgeri, WSC senior department manager. "Working in that way, it took about a month to do the whole thing." The active chemicals diffused into the substrate and reacted with moisture to generate a waterproofing crystalline formation throughout the pores and cap- illary tracts of the concrete. The combination of Xypex Concentrate and Modified was also used by WSC to waterproof four 60-foot long by two-foot wide concrete trench drains at grade level, as well as hundreds of feet of arced knee wall used around the new, circular entrance of the expanded and renovated Gateway Arch National Park. Finally, it should be noted that esthetic bene- fits are possible with restorative products, such as those available from Mapei Canada. "We've added some new products to our resinous flooring category this year," says Yoanna Pergantis, marketing direc- tor. "Mapefloor EP19 or EP20 can be used to address damaged floors, and the Mapefloor I 302 SL resinous flooring system that can be applied on top of that; plus, our decorative quartz or vinyl flakes can be added to impart a pleasing visual element. In fact, we have over 50 colours and blends to choose from that can be broadcast into the flooring and sealed with Mapecoat Universal." Mapefloor EP19 is a three-component, epoxy binder for industrial flooring, specifically designed to enhance adhesion of multilayer floor systems, such as Mapei's Mapefloor EP20 and Mapefloor I 302 SL system (which is an epoxy resin suitable for self-smoothing and textured coatings as well as multi-layering broadcast systems and seal coats for epoxy mortar screeds). EP19 is typically applied on concrete surfaces that require levelling with a slight slope and for repairing deteriorated concrete such as floor slabs in institutional buildings, storage, and logistical areas. The vinyl flakes Pergantis refers to are composed of water-based resin materials, inorganic miner- als, additives, and pigments. They are available in a variety of solid colours and unique colour blends and greatly enhance the appearance of everything from department stores to educational institutions.
