Get Standing Water Out From Under Your House
Epp Foundation Repair pumps out a flooded crawl space and installs the interior drainage and sump system that keeps it dry. Standing water under a home feeds mold, rust, and rot, and it rarely clears on its own.

A local specialist will inspect your foundation, walk you through the findings, and send a clear estimate, no cost, no pressure.
Crawl Space Water Removal: how it works and when it's the right call.
Water removal in a crawl space works in two stages: get the standing water out now, then install a system that handles it automatically going forward. Epp Foundation Repair first pumps out the existing water and lets the crew see where it collects and how fast it returns. Standing water under a house comes from groundwater, not a leak you can patch. Saturated soil builds hydrostatic pressure, the upward push of water against the underside of the floor, and that pressure forces moisture up through the soil and any cracks. Eastern Nebraska and western Iowa sit on expansive clay and loess that hold water and drain slowly, and after a heavy spring rain or snowmelt the soil can stay saturated for days. The permanent fix is interior perimeter drainage. Epp digs a shallow trench around the inside edge of the crawl space, sets a perforated drain pipe in clean gravel, and slopes it toward a low point. Groundwater that would otherwise pool on the floor enters the pipe and runs to a sump pit. A sump pump in that pit switches on automatically when the water rises and lifts it out through a discharge line that carries it well away from the foundation. Epp typically adds a battery backup pump, because the heaviest storms in this region are exactly when the power is most likely to fail. With the water managed, Epp usually finishes by laying a heavy vapor barrier across the crawl space floor and up the walls. The barrier keeps ground moisture from evaporating into the air under the house, so the space stays dry, the wood framing stops absorbing damp, and the conditions that grow mold and rust no longer exist. The system runs on its own with little maintenance beyond an occasional pump check.

How we install crawl space water removal.
Step 01.Pump Out and Diagnose the Source
Epp Foundation Repair pumps out the standing water and inspects where it collects and how quickly it returns. The specialist confirms the water is groundwater under hydrostatic pressure rather than a surface issue and lays out the fix in a Customized Repair Estimate.
Step 02.Install Interior Perimeter Drainage
The crew cuts a shallow trench around the inside edge of the crawl space, beds a perforated drain pipe in clean washed gravel, and slopes it toward a low point. The pipe collects groundwater before it can pool on the crawl space floor and carries it to the sump pit.
Step 03.Set the Sump Pit and Pump
Epp digs a sump pit at the low point, sets a basin, and installs a pump that switches on automatically as water rises. The discharge line carries water well away from the foundation. A battery backup pump is typically added so the system keeps working during the storm-season outages this region sees most.
Step 04.Lay the Vapor Barrier
With the water managed, the crew lays a heavy vapor barrier across the floor and up the walls to stop ground moisture from evaporating into the crawl space air. This keeps framing dry and removes the dampness that feeds mold and rust, finishing the space as a dry, controlled environment.
"Anybody can pump the water out. If you don't install drainage to a sump, you'll be pumping again after the next storm. We fix where the groundwater goes, not just what's on the floor today."

Crawl Space Repair warning signs this solution resolves.
Each problem sign below is a symptom this solution is engineered to fix. See how we diagnose it before we recommend this method.
Crawl Space Mold
Epp Foundation Repair has diagnosed crawl space moisture conditions across Nebraska, Iowa, Kansas, and Missouri since 1994. Mold spores exist in every crawl space. They only colonize when humidity stays above 60% for 48 hours or more.

Deteriorating Insulation
Fiberglass batts drooping between your floor joists or falling to the crawl space dirt. The insulation itself is the symptom. The cause is humid air and ground moisture that the insulation can no longer hold back.

Groundwater Seepage
Epp Foundation Repair has been installing interior crawl space drainage and sump systems across Nebraska, Iowa, Kansas, and Missouri since 1994. The only permanent answer to seepage driven by a high spring water table.

High Energy Bills
Heating and cooling costs creeping up while your thermostat stays the same. A damp, vented crawl space pulls in outside air and lets conditioned air leak out through the floor. Your system runs longer to make up the difference.

Moisture in Crawl Space
Epp Foundation Repair has been encapsulating crawl spaces across Nebraska, Iowa, Kansas, and Missouri since 1994, dropping relative humidity from 75%+ down to a stable 50 to 55%. The threshold where mold cannot colonize.
