The Terrain Factor

Most of the KC metro is fairly flat. Platte County is not. Drive through Parkville or along the river bluffs and you will see houses perched on slopes, cut into hillsides, and sitting on ground that goes from mildly steep to downright sharp. That changes how a foundation moves, drains, and cracks.

Hillside homes deal with three big issues that flat lots usually do not: water runoff stacking up against the uphill foundation wall, soil creep slowly pushing downhill over the years, and uneven settling where one side of the house is on solid rock and the other is sitting on fill or softer material.

We have worked on Parkville basements where the uphill wall was bowing from pressure while the downhill wall looked perfect. The right repair might be wall anchors on the high side to stop the bowing and push piers under the low side where it is settling. Every hillside foundation in Platte County is its own puzzle, and it takes experience to get it right the first time.

River Soil and What It Means for Your House

Closer to the Missouri River — Riverside, the lower parts of Parkville, and areas near Platte Landing — the soil changes. Instead of the heavy expansive clay that most of the metro fights with, you see alluvial deposits: fine, sandy, silty material the river laid down over centuries of flooding.

Alluvial soil behaves differently under a house than clay. It does not swell and shrink with moisture to the same extreme, but it can compress and settle in an uneven way, especially when part of the foundation is on alluvial soil and another part is bearing on native clay or the rock of the bluff.

In these river-bottom and low-bluff situations, we typically install push piers driven deep enough to pass through the loose alluvial layer and reach stable bearing strata below. Depth can vary a lot — 20 feet on one house, 35+ on the next — but the goal is the same: transfer the weight of your home onto soil or rock that is not going anywhere.

Drainage on Slopes

If your home is on a hill and you are getting water in the basement, the problem is almost always drainage, not just “a damp wall.” Water runs downhill, loads up against the uphill foundation wall, and finds its way in through cracks, cold joints, and block cores. A coat of waterproof paint on the inside will not stop that kind of water pressure.

We tackle slope drainage from both inside and outside. Interior french drains pick up any water that gets through and carry it to a sump pump for discharge. Outside, we correct grading and, when needed, install an exterior drain system to intercept groundwater before it ever reaches the wall. Working together, those systems keep Platte County basements dry through heavy spring and summer storms.
