Basement waterproofing in Peosta, Iowa
Waterproofing help for the growing town along U.S. 20, at the edge of the region's wooded bluffs.
Peosta is a Dubuque exurb with 1,908 residents at the 2020 census, up from 1,377 in 2010. U.S. Route 20 runs along its southern edge, and it is home to the largest campus of Northeast Iowa Community College. Much of its housing is recent, on poured or block foundations.
How does the landscape affect basements here?
The Iowa Geological Survey describes the Silurian Escarpment, a winding line of wooded bluffs that forms the western and southern edge of the Paleozoic Plateau, as running past Peosta. Along steep valley sides in this region, the survey notes, springs are common where valleys cut into the water-bearing rock. A house set into a slope can sit right in the path of water moving downhill through the soil, even if the yard looks dry on the surface.
Where does the water usually show up?
On sloped lots it's typically the uphill wall, or the corners where runoff from the slope and roof water meet. On flatter lots in newer neighborhoods, it's more often settled backfill and short downspouts. Sump pits that run long after a storm can be a sign of groundwater moving under the slab.
Common Peosta jobs
- Footing drains and exterior membranes on uphill walls

Why does my sump pump keep running days after it rains?
Often it's groundwater still draining through the soil and rock uphill of the house. It can also be a stuck float or a discharge line letting water flow back. Have it checked so the pump doesn't wear out.
