The answer to 'why is my patio erosion' is that patio erosion is a common issue caused by water runoff, soil instability, or improper patio installation. Symptoms include uneven surfaces, cracks, and loose pavers or stones. Solutions can range from simple DIY fixes to more extensive professional landscaping work.
Patio erosion is often caused by water drainage problems, where rainwater or irrigation runoff is not properly diverted away from the patio. This can lead to soil being washed away, causing the patio surface to sink or shift. Improper grading or lack of a drainage system are common culprits. Soil erosion can also occur due to unstable soil conditions, such as high clay content or poor compaction during installation.
