Denver series soils are slow to drain: fine, smectitic clays formed from calcareous sedimentary rock, with saturated hydraulic conductivity low enough that water reaching a slab stays in the profile. Smectite means the clay swells when wet and shrinks when dry, so slabs on it move with the seasons.
We route epoxy flooring requests in the Denver area to local crews. Ask for itemised written quotes so preparation method, film thickness and warranty can be compared side by side.
Thornton runs its own water utility, sourced and treated separately from Denver Water, so a hardness figure quoted for Denver does not apply here.

Thornton covers the northern metro in Adams and Weld counties, with a large share of 1990s and 2000s construction on Denver-series clay and former farmland. Slabs there are usually newer and better graded than the inner-ring suburbs, but the clay does not change.
The City of Thornton issues its own permits through Thornton Community Development.

'}A working shop slab needs its staining placed correctly before a system is chosen. Chemical resistance in this trade is rated by contact time - Long Term (LT) means 72+ hours of contact and Splash and Spill (SS) means cleaned within 24 hours - so a floor that sees hydraulic fluid, coolant or solvent is a different specification from a garage that only sees dust.

NWS Denver/Boulder climate figures for the valley: January mean highs about 45 °F and mean lows about 25 °F, July mean highs about 90 °F with a record of 108 °F on 16 July 2023, and a record low of −16 °F on 7 Feb 1989 (weather.gov NWS Denver/Boulder climate). The same slab freezes through winter with ice-melt residue tracked in and then bakes under strong summer UV in air that runs dry in July. Denver-area frost depth is 36 inches, and any new pour needs 28 days of hydration before coating.
