Epoxy Flooring in Bismarck, ND

Epoxy flooring in Bismarck has to handle a long, cold, gritty winter. Wikipedia lists Bismarck's average snowfall at about 50.5 inches a year, a January daily mean of 12.8 °F, and a record low of −45 °F. Every snowfall means plows and treated roads, and whatever is on the road ends up on your garage floor. A coating here has to stay bonded through months of hard cold at the overhead door and still clean up easily when the slush melts off the car.

What comes in on your tires

Bismarck treats its streets with a mix of materials. During the 2021 to 2022 winter, KFYR-TV reported the city had used nearly 38,000 gallons of beet brine, more than 17,000 gallons of salt brine, 190 tons of salt and more than 2,300 tons of sand. That combination does two kinds of damage. The brine and salt soak into bare concrete, and a South Dakota DOT literature review prepared by the Michigan Tech Transportation Institute in 2008 found sodium chloride causes severe scaling under freeze-thaw cycling. The sand is abrasive. Ground under tires and boots, it scratches and dulls whatever finish is on the floor. We plan for both by bonding the coating to ground concrete and finishing with a hard, chemical-resistant topcoat.

Newer slabs, bigger garages

Bismarck's housing is younger than many Midwest cities. American Community Survey figures summarized by Point2Homes put the median year built at 1985, with about 19% of homes built between 2010 and 2019 and another 12% from the 2000s. Wikipedia notes that much of the city's recent residential growth has come on the north side. Newer houses usually mean attached two- and three-stall garages with slabs in decent shape. Decent shape does not mean ready to coat. New concrete often carries a cure-and-seal product that has to be ground off, and builder slabs commonly have shrinkage cracks along the control joints. The older 1970s and earlier neighborhoods closer to downtown have their own issues: patched slabs, old paint, and cracks that have moved for decades.

Basements, humidity and radon

Wikipedia describes Bismarck summers as warm and humid, with an annual average relative humidity of 66.4%. The EPA advises keeping indoor humidity below 60%, ideally between 30% and 50%, and notes that condensation forms where warm, humid air meets a cold surface. A basement slab in July can be exactly that surface. We test for moisture before recommending any basement system. North Dakota also has a radon problem: the state Department of Environmental Quality reported in January 2026 that 63% of North Dakota homes have radon above the EPA action level. A floor coating is not a radon system, so we recommend a radon test before you finish a basement.

The systems we install

• Epoxy base with a polyaspartic topcoat: a thick, well-bonded base coat with a UV-stable, abrasion-resistant top layer.
• Full flake broadcast: colored chips scattered into the base to full coverage, which hides sand and salt residue and adds grip.
• Polyaspartic systems: quick-curing coats that shorten the time your garage is out of service and that HomeGuide says can go down across a wide temperature range.
• Metallic epoxy: a poured, marbled finish for basements, bars and finished rooms.
• Shop and commercial floors: thicker 100% solids systems for equipment, heavy trucks, fuel and fluids.

What happens on install day

• We protect walls and doors and confirm what has been moved out
• The slab is diamond ground wall to wall, then vacuumed
• Cracks, pits and spalled spots are filled and ground flush
• Base coat, color or flake, and a clear topcoat go down in order
• You get written cure times for walking, moving items back and parking

Bismarck is the center of our work, and we cover the rest of the Bismarck-Mandan metro and nearby towns. Across the river, Mandan has an older core and plenty of shops. Lincoln, a fast-growing suburb on Bismarck's southeast edge, is full of newer attached garages. North of town we work in Regan, Baldwin, Wilton and Washburn. East along I-94 we cover Menoken, McKenzie, Driscoll and Sterling. West and northwest we travel to New Salem, Almont, Flasher and Center. Rural properties often have a pole barn or shop slab as well as a garage, and those floors see farm equipment, diesel and grit. Each area page explains what we see there.
