It is a pattern that Phoenix homeowners know all too well. Beginning in July, the Arizona monsoon season begins with an increase in thunderstorms and heavy rainfall typically lasting until mid-September.
While the season is short, Ahwatukee residents can easily experience an upward movement of the ground below their foundation as the area’s clay soils swell with increased moisture. Known as “ground heave,” the impact can be long lasting, with cracks in brickwork, floor tiles, or windows as telltale signs.
Although the forecast for this year’s monsoon season calls for a slightly later arrival, the rains are expected to be heavier than usual. And the monsoon can indeed be wet.
