Basement waterproofing in Mankato
Waterproofing help across the city, from the river flats to the bluffs above them.
Mankato is the seat of Blue Earth County and had 44,488 residents at the 2020 census. Most of the city is in Blue Earth County, with smaller pieces in Nicollet and Le Sueur counties. It grew up on a large bend of the Minnesota River where the Blue Earth River flows in, and the city spreads from the valley floor up onto the bluffs.
Flats versus bluffs
Homes on the lower ground near downtown and the rivers deal mostly with groundwater during wet springs: seepage at the floor joint and sumps that run for weeks. Up the hill, the problem is more often runoff. Steep streets and stacked lots send water from one yard to the next, and the uphill wall of a basement takes the brunt.
Age of the housing
Older neighborhoods near downtown have many homes with block, brick or stone foundations built before modern drain tile was standard. Rentals near Minnesota State University often need egress windows when basement rooms are used as bedrooms. Newer homes in the hilltop subdivisions usually have poured walls and a sump from day one.
Common Mankato jobs
- Interior drain tile in older basements without working footing drains
- Regrading and swales on hillside lots
- Egress windows for rental basement bedrooms
- Bracing bowed block walls
Common questions
Do the river levees keep my basement dry?
They protect against river flooding. They don't stop rain, snowmelt or groundwater from seeping into a basement, which is what most waterproofing addresses.
