What makes Ames basements different
Ames sits on the Des Moines Lobe astride the Skunk River and Squaw Creek, with a large stock of older housing near campus and extensive newer development on flat ground north and west. The 2010 flooding remains the local benchmark for low-lying basement risk near the river corridors.
Polk County sits on the Des Moines Lobe — the youngest glacial landscape in Iowa, left by ice that retreated only about 12,000 years ago. The soils are the Clarion-Nicollet-Webster association: Clarion well drained on the rises, Nicollet somewhat poorly drained on the slopes, and Webster poorly drained in the low ground. Roughly 60 percent of the landscape is classed as aquic — wet by default. That is the mechanism behind most of what we see in Story County: not rainfall volume, but clay that refuses to drain and holds the water against the wall until it finds a way through.
Because the Lobe is so young, natural drainage networks have not had time to cut. Relief across much of the metro is under five metres, and water that lands here does not run to a stream — it sits until it soaks in or evaporates. With 37.1" of rain and 36.5" of snow a year, and a 42" frost line driving freeze-thaw cycling, the loading is seasonal and relentless rather than occasional.
Services available in Ames
Basement Waterproofing
A wet Des Moines basement is usually a volume problem, not a pressure problem. Central Iowa ground is flat, young and internally drained — when a July storm drops three inches in an afternoon, the water has nowhere to go.
Foundation Repair
Foundation problems in Central Iowa come from two directions: lateral load from saturated till, and footings settling into ground that was never as stable as it looked.
Wet Basement Repair
Des Moines basements leak on a trigger, and the trigger is usually a single storm. Which opening the water used decides whether the fix costs hundreds or five figures.
Sump Pump Installation
In Central Iowa a sump pump is sized for a thunderstorm, not a season. The design event is two to four inches falling in an afternoon onto ground that cannot take it.
French Drain Installation
On flat Des Moines Lobe ground, water does not run off — it waits. A French drain gives it somewhere to go that is not your foundation.
Foundation Crack Repair
Width, direction and movement tell you everything. A hairline running vertically down a poured wall is the concrete relieving its own curing shrinkage. A crack tracking horizontally along a mortar bed is the ground outside winning.

Ames questions

What causes wet basements in Ames?
Ames sits on the Des Moines Lobe astride the Skunk River and Squaw Creek, with a large stock of older housing near campus and extensive newer development on flat ground north and west. The 2010 flooding remains the local benchmark for low-lying basement risk near the river corridors. Behind that local factor sits one shared condition: the Des Moines Lobe is the youngest glacial landscape in Iowa, so flat that natural drainage has never had time to form. Water that lands does not run anywhere — it waits, and during a summer storm it arrives faster than the ground can take it.
What does basement waterproofing cost in Ames?
The same Polk County ranges apply: interior perimeter drainage $5,000–$15,000, crack injection $400–$1,200, bowing wall stabilization $4,000–$15,000, and exterior excavation $12,000–$30,000. Scope is set by an on-site inspection, not by the phone call.
Do I need a permit in Story County?
Interior drainage and sump work generally does not require one. Structural foundation repair and cutting an egress window do, and in Story County those go through the county building department. Any contractor unwilling to pull a permit for structural work should be disqualified on that alone.
