Why Gravel Driveways Wash Out After Heavy Rain
Gravel driveways can wash out when rainfall carries loose material away faster than it can settle. In areas like the Fraser Valley, where rainfall can be heavy during certain seasons, poor drainage and improper base preparation are common causes of driveway erosion.
When water flows directly across the driveway surface, it can create channels that gradually remove gravel and expose the soil underneath.
Insufficient Base Preparation
A gravel driveway needs a stable base beneath the surface layer. Without enough base material, the gravel can shift and move when vehicles pass over it or when rainwater runs across the surface.
Over time, this movement allows water to erode the driveway more easily.
Poor Drainage Around the Driveway
Drainage is one of the most important factors in maintaining a gravel driveway. If the driveway is flat or slopes incorrectly, water can travel down the driving surface instead of draining off to the sides.
Proper grading and drainage design help prevent this type of erosion.
Restoring the Driveway Surface
Repairing a washed-out driveway usually involves regrading the surface and redistributing gravel to restore the correct slope. In some cases, additional base material must be added and compacted.
Our gravel parking lot grading and regrading services are often used to repair driveways and parking areas that have developed erosion problems.
Preventing Future Washouts
Maintaining proper drainage and periodically reshaping the surface can significantly extend the life of a gravel driveway. Addressing small erosion issues early prevents more extensive repairs later.
