Foundation movement opens a diagonal crack

Differential support or movement redistributes stress around openings and finishes.

  1. Support conditions change.
  2. Loads redistribute through the structure.
  3. Openings concentrate stress.

A blocked gutter wets the foundation

Overflow concentrates roof runoff beside the wall, increasing splash, soil moisture and below-grade water pressure.

  1. Debris restricts gutter flow.
  2. Water spills at the eave.
  3. Runoff saturates soil near the foundation.

A short downspout extension recycles water at the foundation

Roof runoff exits too close to the wall and repeatedly loads the same soil and foundation area.

  1. Roof area concentrates a large water volume.
  2. The downspout releases beside the wall.
  3. Water follows backfill and service trenches.

Slab edge creates a cold floor band

Heat flows through a concrete perimeter with limited insulation, creating a repeatable cold strip inside.

  1. Outdoor temperature falls.
  2. Concrete conducts heat toward the exterior.
  3. The floor edge cools faster than the room center.
