Watrous Heights: Foundation & Waterproofing by JLB

What Foundation and Waterproofing Challenges Affect Watrous Heights?

On the Southside flats where Watrous Heights sits, water doesn't run off — it collects. The neighborhood's mid-to-late-20th-century ranch homes were built low and wide across ground that sits closer to the water table than the higher parts of Des Moines, and that low position is what drives the foundation issues here.

The clay-heavy soil of the Des Moines Lobe swells with every wet cycle, and in these lower-lying zones the moisture lingers long after a storm. Expanding clay presses in on basement walls, and when a heavy rain or a spring melt arrives, the water has nowhere to go but toward the lowest point in the house — often the basement floor. For a ranch on a full or partial basement, that makes two things non-negotiable: walls that can carry the seasonal pressure, and a sump you can actually count on when the water rises.

JLB handles both sides of that. We stabilize walls feeling the lateral push from the clay, and we build the drainage to match the ground — interior drain tile feeding a reliable sump with battery backup, so a hard rain on the flats doesn't finish with water across the floor.

In a neighborhood this low and this flat, sump reliability isn't a nice-to-have. It is the difference between a dry basement and a flooded one every wet season, and that is the standard we hold a Watrous Heights system to.
