What causes parking lot heaving?

Parking lot heaving can occur due to various reasons, such as soil expansion and contraction, freeze-thaw cycles, and inadequate drainage. When the temperature changes, the soil beneath the parking lot expands or contracts, resulting in the upward movement of the pavement surface. In locations with colder climates, moisture within the soil can freeze and expand, causing the pavement to lift as it thaws. Also, poor drainage can cause water to accumulate beneath the parking lot, leading to the erosion of the soil base and subsequent heaving. As a consequence, it is essential to monitor and maintain good drainage systems and invest in high-quality construction materials to prevent parking lot heaving.
