The answer to stone walkway erosion is that it is a common issue caused by factors like heavy foot traffic, water runoff, and soil shifting. Symptoms include uneven surfaces, cracks, and loose stones. Solutions range from minor repairs to complete walkway replacement, depending on the extent of the damage.
For minor erosion, homeowners can often DIY with basic landscaping skills. This may involve resetting displaced stones, filling cracks with polymeric sand, and improving drainage. However, for significant damage or structural issues, it's best to call a professional landscaper or masonry contractor to assess the walkway and recommend the best long-term solution.
