Foundation repair, basement waterproofing and concrete leveling in Topeka, KS.

Shawnee County sits on Pennsylvanian shale overlaid with heavy clay. The clay swells dramatically when wet and shrinks in dry summers, creating enormous seasonal pressure on foundations. Topeka also has freeze-thaw cycles that compound this movement.

The USDA soil survey inside Topeka comes back Pawnee at about 60 percent of the survey, with Martin and Ladysmith alongside it. The texture split is 78 percent clay and 10 percent silt. Linear extensibility, the measure of how much a soil swells when it takes on water and shrinks when it dries, is weighted at 6.93 percent here, which USDA reads as high shrink swell potential. Against 78 percent clay across Shawnee County, the city sample reads 100 percent. Karst features are mapped in this area, so voids and sinkhole risk are part of the inspection. Based on NOAA 1991 to 2020 climate normals for Topeka Municipal Airport, precipitation averages 36.5 inches a year and about 114 days a year have a low of 32 degrees or colder, so the soil beside a wall can be wet, dry or frozen at different times of the year. What is actually happening at your address is something we confirm on site, not something we read off a map.

The typical house dates to 1967, and the single biggest block of the stock, 10,440 homes, went up before 1940. 41,932 of those homes predate 1980, which is where we most often find footing drains that were never installed and backfill that was never compacted. 20 percent of the housing here, 10,926 units, sits in buildings of five or more, so a fair share of local work is on shared structures rather than single family homes. Of the owner occupied homes, 56 percent carry a mortgage. Every inspection ends with a Customized Repair Estimate that describes what we found at that house.
