Commercial and industrial flooring covers the heavier-duty end of the epoxy trade: warehouse floors, manufacturing plants, loading bays, auto shops, food processing facilities, and large retail or office spaces. Unlike a garage floor coating, these jobs usually deal with bigger square footage, forklift and pallet-jack traffic, chemical exposure, and tighter deadlines because a shut-down production floor costs a business money every hour it's out of service. Contractors working in this category typically use industrial-grade epoxy, polyaspartic, or polished concrete systems, and often add moisture vapor barriers, control joint repair, and anti-slip or anti-static additives depending on what the space is used for.
Markham has 11 businesses listed under this category, ranging from small crews that handle a mix of residential and light commercial work up to outfits built specifically for industrial-scale projects. When you're comparing them, look at whether they've handled floors your size before, whether they do proper concrete moisture testing and surface grinding before coating (skipping this step is the top reason floors fail early), what warranty they put in writing, and whether they can work around your operating hours to limit downtime.
Our scoring weighs verified reviews, responsiveness, licensing and insurance, and evidence of industrial project experience, so you're not just guessing based on a flashy website.
