Garage floor coating in Louisville, Colorado

Louisville has three kinds of garage. Old Town around Main Street has 1900s miners' cottages and bungalows with detached garages and slabs that may be the original pour. Coal Creek Ranch, Centennial Valley and Harper Lake have 1980s and 1990s two- and three-car attached garages. And since 2022, hundreds of homes in the eastern neighborhoods have been rebuilt after the Marshall Fire, which means brand-new slabs behind brand-new garage doors.

Rebuilt homes are a big part of the Louisville picture. A new slab is a great candidate for coating, but timing matters. Concrete keeps releasing moisture for months after it is poured, and a coating applied too early can lift from underneath. We put a moisture meter on every rebuild slab before we quote. If it reads dry, we coat it. If it does not, we tell you when to check back, and we do not charge for the visit.

For the older slabs, the story is scaling and heaved joints. Thirty winters of mag chloride dripping off the car weakens the top skin of the concrete, and expansive soil lifts one side of a control joint a little higher than the other. We grind the surface to sound concrete, grind the joint edges flush, fill them with flexible filler and coat straight over the top so the floor is continuous.
