Floors for a Country Address Close to Town
We do epoxy flooring in Renner for people who want room to spread out without being far from Sioux Falls. Renner is an unincorporated community on South Dakota Highway 115, in the Big Sioux River valley just north of the city. The Census Bureau counts its residents in Mapleton Township, which had 2,099 people in 2020. Many properties here have more than one building with a concrete floor, and each one may need a different system.
One property, several floors
A typical Renner visit can include three very different slabs: 1. The attached garage. Daily parking, winter salt and gravel from rural roads. A flake garage floor coating with a tough topcoat is the usual choice. 2. The shop or outbuilding. Equipment, trucks, fluids and heavy tools. Commercial and shop floor epoxy, built thicker, handles that work. 3. The basement. Storage, a family room or a home office. Basement floor epoxy or a metallic finish, after a moisture test.
We can quote all three at once and schedule them back to back.
Valley ground and basement moisture
Renner sits low in the Big Sioux River valley. We do not assume any basement is wet, but valley homes are a good reason to test before coating. We check moisture in several spots on the slab. If the readings are high, we use a moisture-tolerant primer. If there is an active leak or standing water, we will tell you to deal with drainage first, because no coating will fix a water problem.
Gravel, dust and grip
Country driveways and roads bring a lot of grit into a garage. Fine gravel acts like sandpaper under tires and boots. A flake system hides that dust between cleanings, and the clear topcoat protects the color. We can also add texture near entry doors so the floor stays safe when it is wet.
A place with history
Renner was founded in 1898 and named after Leonard Renner, a local farmer whose land held the depot built in 1907. In 1923 it was the site of one of the earliest rural electrification projects in the country. Renner Lutheran Church, started by Norwegian immigrants in 1868, is listed on the National Register of Historic Places. Some older farmsteads in the area still have outbuildings with concrete floors that have been in use for decades. Those slabs can often be ground, repaired and coated.
Planning around the seasons
People with shops and acreage are often busiest in spring and fall. If your outbuilding is full of equipment during those months, winter or midsummer may be the better time to coat it. A heated shop can be done in cold weather. For an unheated building, we plan around a stretch of warmer days or use a product that cures at lower temperatures. Tell us when the building is easiest to empty, and we will work from there.

Renner Questions
Can you coat a pole building or outbuilding floor near Renner?
If the building has a concrete slab, yes. We grind, repair and coat it with a shop-grade system. Dirt or gravel floors would need concrete poured first.
My basement is in the valley. Will epoxy stop moisture?
A coating is not a waterproofing system. We test moisture first and use a primer made for damp slabs when readings allow. If water is coming in, that needs to be fixed before we coat.
Can you do the garage and the shop in one trip?
Usually, yes. We plan the schedule so curing on one floor overlaps work on the next.
