VersiDrain 25P is a plastic water retention and drainage tray designed to both store and facilitate the efficient discharge of excess subsoil water. It is used in the construction of green roofs to conserve water used for. It allows water and soluble nutrients stored in the cells to be returned, via evaporation and capillary action, to the planting media during dry periods reducing irrigation frequency whilst large holes in the channels allow excess water to be efficiently drained away preventing water-logging and promoting healthy plant growth in wet periods.
- Root-impenetrable and rot-proof
- Retains water for plant irrigation
- Efficient drainage of excess water
- Resistant to biological attack and soil-borne chemicals
- Narrow profile enables greater media depth
