Central Texas sits on expansive clay soil that swells when wet and shrinks when dry. This seasonal movement stresses underground pipes at joints and fittings. During summer droughts, the clay contracts and pulls away from pipes, creating voids. When fall rains arrive, the soil expands rapidly and applies pressure to weakened connections. Pipes installed in the 1970s and 1980s, before flexible bedding materials were standard, experience the worst damage. Live oak and cedar elm roots also exploit these weakened joints, penetrating cracks to access water and widening the failure.
