M A R C H 2 0 2 4 | 59 Restoration Products & Services Morin's team recently finished a three-year phased stint of brick and stone replacement plus structural upgrading of the Chateau Frontenac in Quebec City, and projects in Charlottetown and Cape Breton are currently keeping the company busy. "Also, in Saint John, New Brunswick we're restoring the Carleton Martello Tower, which dates back to 1812 and is made of extremely thick stone, brick, and mortar," Morin says. "We're disman- tling the structure brick by brick and resetting every piece, which requires a lot of know-how." The res- toration even includes laboratory testing of the old mortar to determine its composition, in order to decide the proportional mix of new formulations. Mick Kopis, marketing director at Mapei Canada, is especially proud of the ICRI's recognition of the McGill University Strathcona project and notes that no less than 11 different products from his com- pany were used, including the high-performance fast setting Mapecem Quickpatch; MapeWrap 12 (structural epoxy putty adhesive); Planitop 23 (ver- tical and overhead repair mortar); and Planitop 25, a shrinkage-compensated, cementitious, flowable resurfacing mortar with a corrosion inhibitor. Mapei is famous for developing long-lasting products that serve every type of construction need, and recently the company introduced a new family of carbon-neutral products. They include Mapecem Quickpatch and a variety of other mortars, and they join the company's CUBE System and Re-Con line of cement admixtures, which reduce the carbon lev- els of the concrete mix itself and turn waste concrete into usable material, respectively. Even though Heidelberg Materials isn't a resto- ration and repair specialist, sales manager Byron Young points out that contractors occasionally use its shotcrete or concrete for such projects, and he is particularly proud of Heidelberg being involved in the MacLeod Building Renewal at the University of British Columbia – for which Heatherbrae Builders won a 2023 ACI Excellence in Concrete Construction award. "The concrete was supplied by our team at Ocean Concrete," he says. The concrete being used to refresh the university's electrical and computer engineering facilities after the 1967 building was renovated down to its basic structural elements. Maxime Duzyk, global director, building science and engineering at Huntsman Building Solutions, reports that his company's insulation solutions were deployed in a host of projects in 2023, and the New Year is shaping up to be equally busy. Huntsman Building Solutions' spray foams and coatings continue to earn designations that boost their status as important solutions not only for new builds but also in the restoration realm. Duzyk points out that HBS coatings are among the best solutions for below-grade waterproofing, while the spray foam products can help add structural strength, prevent wind uplift, reduce embers from entering attics, are resistant to floods, act as a radon barrier, and have a higher wind load resistance. Last year, Huntsman Building Solutions received product code compliance (NBC 2015) recognition from the Canadian Construction Materials for its Radon Protection System, i.e.: the Heatlok Soya HFO, a closed-cell polyurethane spray foam insulation that has proven to be an effective radon barrier. Duzyk says. "The key difference between our prod- ucts versus others is that only 38 millimetres [mm] of spray foam is needed for a solid soil gas barrier, versus other spray foam products needing 50mm. This year, Huntsman Building Solutions is set to convert all its production to Heatlok Soya HP, boast- ing the highest R-Value in the industry. It is also Greenguard Gold certified, and has undergone test- ing for radon diffusion, air barrier systems, and fire resistance to meet Canadian requirements for tall buildings. Additionally, in 2024, the com- pany's Coatlok Coatings achieved UL certification. These waterproofing polyurea products are non- toxic, fast drying, and can be applied to virtually any shape to create a monolithic waterproofing barrier. Brian Salazar, national business development manager at Euclid Canada, corroborates the senti- ments of his colleagues regarding the restoration sector in 2024 when he says, "We seem to be very busy despite the economic headwinds; there are no slowdowns to speak of." It helps that Euclid continues to make the process of restoration easier and more effective with a steady stream of new and refined products, the latest of which is Level Top PC-AGG, which Salazar describes as "an interior overlay material that imparts a new concrete look. It's a cement-based and polymer mod- ified product that can be polished just a day after it is poured. It's great for resurfacing old, beat-up floors, and is stronger than the concrete it's bonded to, so it's extremely long-lasting." Part of the resiliency is due to micro-fibres that prevent shrinkage and cracking.
