Answer:
No, artificial grass will not rot your decking when installed correctly. It is designed with perforations that allow water to drain through, preventing moisture build-up. As long as your decking has adequate ventilation and drainage, artificial grass will sit safely on top without causing damage.
This applies to both composite decking and natural timber decking, though the material type can impact long-term maintenance needs.
Composite vs Natural Wood Decking: Which Is Better for Artificial Grass?
| Feature | Composite Decking | Natural Wood Decking |
|---|---|---|
| Moisture Resistance | Highly resistant to water and rot | More prone to moisture damage over time |
| Maintenance | Low-maintenance (no staining or sealing) | Requires regular treatment/sealing |
| Durability | Extremely durable, doesn’t splinter or warp | Can warp or crack if not well maintained |
| Lifespan with Artificial Grass | Ideal under artificial grass | Safe with proper airflow and drainage |
| Visual Appeal | Sleek, uniform appearance | Natural and traditional look |
✅ Tip: Whether you have composite or timber decking, we recommend:
- Cleaning the surface before installing artificial grass
- Ensuring drainage gaps remain unblocked
- Using breathable underlay if additional airflow is needed
