Multiseal

What Multiseal does

Multiseal is a privately held specialty construction contractor founded in 1977 and headquartered in Toronto, Ontario, with a US subsidiary (Multiseal Corporation) based in Buffalo, New York. The company delivers project-based construction services across four integrated divisions: Waterproofing (below-grade waterproofing, roofing and terraces, green roofs, traffic decks, and the proprietary Multiguard Traffic Deck System); Hardscapes (streetscapes, enhanced crosswalks, traffic calming, alternate transportation infrastructure, and commercial parking lots using StreetBond, StreetPrint, and TrafficPatternsXD products); Restoration (parking garage structural repair using NEFMAC and MBrace composite reinforcement systems); and Paving (commercial asphalt paving, crack sealing, and preventive maintenance using the DuraShield acrylic coating system).

The technical core of the offering rests on proprietary branded materials developed through four decades of field experience, notably the Multiseal 1080 hot-applied rubberized waterproofing membrane and the Multiguard Traffic Deck System, supplemented by certified applicator rights to HUB Surface Systems' decorative and traffic-calming product families and composite strengthening materials from structural restoration partners. Multiseal is a pioneer in hot rubberized membranes and asphalt toppings, providing single-source specification, material supply, and installation under comprehensive warranty packages.

Multiseal operates a direct sales-led go-to-market targeting architects, engineers, general contractors, and property managers, with project-based, quote-based pricing and no distribution or retail channel. Customer segments are diversified across commercial real estate (Cadillac Fairview, Tridel, H&R Developments), major banks (CIBC), transportation (Canadian Pacific, Metrolinx, VIVA, TTC, MTO Ontario, GTAA), government (City of Toronto, City of Kitchener, Department of National Defense), education (University of Toronto, York University, University of Alberta, SUNY), healthcare (Sunnybrook), and general contracting partners (Ellis-Don, PCL). Revenue is generated through one-time project contracts across Canada and major US urban centers.
