The answer to 'why is my stone walkway erosion' is that stone walkways can erode over time due to a variety of factors, including weather, foot traffic, and improper installation. Common causes of stone walkway erosion include heavy rain and runoff, freeze-thaw cycles, and settling or shifting of the underlying soil or gravel base.
Symptoms of erosion may include cracks, uneven surfaces, loose stones, and weeds or moss growing between the stones. To address stone walkway erosion, homeowners may need to repair or replace damaged stones, improve drainage, or add a new gravel or sand base. In some cases, calling a professional landscaper may be necessary to properly assess and address the issue.
