The answer to 'paver drainage problems' is that common causes include improper installation, poor soil conditions, and clogged drainage systems. Symptoms can include standing water, sinking pavers, and mold/mildew growth. Solutions may involve re-grading, adding drainage features, or completely re-laying the pavers.
For minor issues, homeowners can often address paver drainage problems through DIY methods like cleaning out debris, adjusting soil slopes, or installing additional drainage pipes. However, more complex problems may require the expertise of a professional landscaper or paving contractor to diagnose and resolve the issue properly.
