Checking Slabs After the Shake
Epoxy flooring in Magna starts with a close look at cracks. A magnitude 5.7 earthquake struck on March 18, 2020, with its epicenter in Magna, and more than 850 aftershocks followed. Damage was light overall, though several historic unreinforced brick buildings were hurt. A garage slab that came through fine may still have hairline cracks that opened that spring. We map those before we quote.
How we handle cracks
Not every crack is the same. A stable hairline crack can be filled with a rigid repair material and ground flush. A crack that keeps moving, or one that runs along a control joint, needs to stay flexible or be cut in as a joint, or it will come right back through the new coating. We explain which is which in your quote.
Homes from the mill era
Construction of the Magna Mill began in 1906, and early mill workers lived in town and walked to work. Census survey data dates about 9% of local housing to 1939 or earlier. Old garages and outbuildings from that era may have thin, uneven slabs with no vapor barrier. We test moisture and may suggest leveling or patching before coating.
1970s neighborhoods
In the 1970s, moderately priced single-family homes were built south and east of the historic town center, and about 20.2% of today's housing dates from that decade. Those garages usually need a solid grind and some crack repair, then a flake system that hides minor flaws.
Industrial neighbors
Northrop Grumman runs a solid rocket motor plant in Magna, and the Hercules Bacchus Works began producing rocket motors south of town in the 1960s. Workshops and industrial spaces in the area need chemical-resistant floors that stand up to solvents and heavy carts. We offer thicker commercial systems for those jobs.
Owner-occupied streets
Owners live in about 78.9% of Magna's occupied homes, and single-family detached houses make up 75% of the housing stock. Many owners use the garage as a shop. Light colors and a chemical-resistant topcoat suit that kind of space.

Magna Questions
My garage floor cracked after the 2020 earthquake. Can it be coated?
Most likely. We check whether each crack is stable or still moving. A stable crack gets filled and ground level; a moving one is treated as a joint.
Can a very old garage slab be coated?
Often, with extra prep. Older slabs may be thin or uneven and lack a vapor barrier. We test moisture and may recommend patching or leveling first.
Do you coat industrial floors near Magna?
Yes. We install thicker, chemical-resistant systems for shops and industrial spaces.
What finish suits a home workshop?
A light-colored flake or solid floor with a chemical-resistant topcoat brightens the space and handles spills.
