Why Northeast Heights concrete settles the way it does
The Northeast Heights is defined by its climb. From roughly 5,300 feet along Comanche up to more than 6,500 feet at the Sandia foothills, almost every lot was cut into a slope and finished on a mix of native decomposed granite, caliche shelf, and imported engineered fill. That fill is what settles. Native ground beneath most Heights subdivisions is dense and stable — the concrete sits on top of the layer that was trucked in and compacted during grading, and that layer continues to consolidate for a decade or more after the home is built. The result is a very consistent pattern across the mid- and far-Heights: driveways drop toward the street, garage aprons pull away from the slab-on-grade inside the garage, and back patios along the uphill side of the lot separate from the door threshold by a quarter inch or more.
