Sump Pump & Interior Drainage
If you have hydrostatic water pressure, water pushing through where the wall and floor meet, a sump pump or below-floor drainage system may be needed. We design and install the right system to successfully channel water away and keep your basement dry for good.

Where Basement Water Actually Comes From
Most basement water is not coming through a hole in the wall. It is coming up through the joint where the wall meets the floor, pushed there by hydrostatic pressure. Saturated soil around your foundation has nowhere to drain, the water table rises against the footing, and the pressure finds the weakest seam in the box.
That is why sealing the wall alone often fails. If the water table is up against your footing, blocking one path just makes it find another. Interior drainage works on the pressure instead of the symptom, by giving the water a route to a pump before it ever reaches your floor.
How An Interior Drainage System Works
Below-floor drain line
We cut the perimeter of the basement floor, install drain line in stone below slab level, and repour the concrete. The line sits at the footing where the water actually collects, intercepting it before it can push up through the joint.
Route to the pump
The drain line carries collected water to a sump basin at a low point in the basement. Everything is graded so water runs to the pit rather than sitting in the line.
Sump basin and pump
A sealed basin set into the floor, with a pump sized for the volume the system will actually see. We size the pump to the house rather than installing whatever is on the truck.
Discharge away from the house
The discharge line has to carry water far enough from the foundation that it does not simply soak back in and cycle through the pump again. Getting this wrong is why some systems seem to run constantly.
Backup considerations
A pump is a mechanical device on household power, and Kansas City storms take out power. We will talk through battery backup or a secondary pump so a storm does not become the thing that floods the basement the system was installed to protect.
Interior Drainage Or Exterior Work?
Interior drainage fits when
Water is entering at the wall-floor joint or up through the slab, the yard cannot be excavated economically, or landscaping, a driveway, or a deck sits over the area that would need to be dug. It addresses the water that reaches the footing regardless of how it got there.
Exterior work fits when
The problem is water arriving at the foundation in the first place: grading pitched toward the house, downspouts discharging at the wall, or a yard that sheds toward the foundation. A French drain and regrading solve that upstream, and often reduce what the interior system has to handle.
What Determines The Cost
We do not publish a price, because a number without seeing your foundation is a guess. Here is what actually moves it, so you know what we are looking at during the free inspection.
- Linear footage of drain line being installed
- Whether the system covers one wall or the full perimeter
- Pump sizing and whether a backup system is included
- Discharge routing and how far the line has to run
- Concrete cutting, removal, and repour of the floor perimeter
- Access and how material moves in and out of the basement
Sump Pump & Interior Drainage FAQs
Occasional water usually means the water table only reaches your footing after heavy or sustained rain. That is exactly the condition a sump system handles. Whether it is the right answer depends on where the water enters, which is what the inspection determines.
Pumps are mechanical and they do wear out. Lifespan depends on how often it cycles, which depends on your water table and your drainage. That is a real argument for fixing exterior drainage too, since a pump that runs less lasts longer.
A standard pump stops. In a metro where storms and outages arrive together, that is worth planning for. We will walk you through battery backup and secondary pump options so you can decide with the actual tradeoffs in front of you.
It manages water reaching the footing and the wall-floor joint. A crack actively passing water through the wall is a separate repair. Many homes need both, and we will tell you if yours is one of them.
Not always. If water is consistently entering along one wall, a partial system may be appropriate. Full perimeter is more thorough. We base the recommendation on where water is actually entering, not on a default.
