Basement Floor Epoxy in Topeka, KS

Basement floor epoxy can turn a dusty lower level into a laundry room, gym, playroom or bar with a floor you can mop. In Topeka the finish is the easy part. The hard part is the slab, because it rests right on the soil. When a basement coating comes loose, moisture rising from underneath is the usual reason. So every basement job we do starts with a look at the ground, the age of the house and a test on the concrete.

Three basements we see a lot

• Pre-war houses: about 16% of Topeka homes date to 1939 or earlier. Floors are often thin, patched and painted several times.
• 1950s and 1960s homes: the largest group. Expect old floor tile, black adhesive, and no plastic sheet under the concrete.
• Newer builds on the edge of town: better slabs, often bare, sometimes sealed. Fewer than 5% of homes here were built after 2010.

Those shares come from 2019 to 2023 American Community Survey figures summarized by Point2Homes, which put the median year built at 1967.

The ground under the slab

The Kansas Geological Survey's map of eastern Shawnee County shows Kansan glacial drift over most of the area, mostly unsorted clay till, resting on beds of shale and limestone. Clay soaks up rain and gives it back slowly. Topeka gets about 36.5 inches of precipitation a year, mostly in spring and summer. Put those together and a basement floor can stay damp for weeks at a time and crack as the soil swells and dries. That does not rule out a coating. It decides which primer we use.

How we read the slab

We look first. White crust along the walls, dark blotches, paint lifting in sheets, rusty legs on metal shelves and a musty smell all point to moisture. Then we tape a square of plastic to the floor overnight and check for condensation under it, and we take meter readings. If vapor is moderate, a moisture-tolerant primer goes down first. If water actually runs in through a crack, the floor-wall joint or the sump after a storm, that leak has to be solved before any floor work.

Old tile, glue and paint

Mid-century basements often hide old floor tile or black cutback adhesive under carpet. Some of those products can contain asbestos, so they should be tested before anyone grinds them. We ask about it at the estimate and will not grind untested tile or glue. Painted floors are simpler: the paint is ground off so the new coating bonds to concrete, not to old paint.

Radon belongs on the list

K-State Research and Extension reports that about one in four Kansas homes tests at or above the EPA action level of 4 pCi/L, and that more than 112,000 KDHE measurements average 4.9 pCi/L statewide. Radon seeps up from the soil through cracks and gaps in the foundation. An epoxy floor does not fix that. Run a test before you finish the room. If you need a mitigation system, put it in first, and we will coat around the suction pipe and sump.

Drains and the sump stay working

We keep floor drains, cleanouts and the sump pit open and reachable. Water still needs a way out after a heavy storm.

Choosing a finish for the room

A solid light color brightens a laundry or storage room with small windows. A chip floor hides lint and gym dust and gives a bit of grip. A metallic pour suits a bar or media room. We ventilate during the work and give you a time for furniture to go back based on the product we used.
