Basement waterproofing across Hennepin County.

Most populous county in Minnesota. Most basements, too.

We cover the cities people actually call us from. Inner-ring Minneapolis neighborhoods are mostly pre-war housing stock with stone or block foundations, low-floor basements built into glacial till, and water table issues driven by the original wetland geometry under the city. The first-ring suburbs (Edina, Richfield, St. Louis Park, Golden Valley) are mostly mid-century rambler infill on the same geology with poured-wall foundations.

The outer-ring (Plymouth, Brooklyn Park, Bloomington east side) is mostly 1970s-2000s subdivision construction on graded-and-filled sites, with their own characteristic problems: hydrostatic pressure from compacted backfill, perched water tables on engineered fill, and surface drainage that was designed before the trees grew in.

The geology is the same. The construction era changes. The water moves the way it always has.

That overlap is the reason we know what we are looking at when we walk into a basement here. After enough Hennepin County basements, the patterns become obvious: which neighborhoods sit over former wetlands, which streets sat downhill from a now-paved drainage swale, which foundations were built in a year that the city was still figuring out its storm sewer design.

The work, county-wide.

Same crew, same warranty, same answer-the-phone service anywhere in Hennepin County.
