MP-S30A is a light-green modular HDPE drainage cell for roof gardens, planted podiums and landscaped decks. Its 333 × 333 × 30 mm format creates an open drainage layer below the filter fabric, helping surplus water move toward planned outlets without mixing the drainage layer with the growing medium.
The original page described this product as a “water storage tray,” but its retained technical table lists water retention as N/A. The product is therefore presented here more accurately as a roof-garden drainage cell while preserving every confirmed legacy specification, image and packing reference.

Typical Roof-Garden Build-Up
The MP-S30A should be treated as part of a complete drainage design rather than a stand-alone waterproofing or structural component. A typical sequence includes the structural deck, waterproofing and protection layers, the drainage cell, filter geotextile, growing medium and vegetation. The project consultant should confirm the final arrangement.
- Coordinate module placement with roof falls and outlet locations.
- Protect completed waterproofing before beginning drainage work.
- Fit adjoining modules tightly to maintain continuous flow paths.
- Form neat details at edges, penetrations and inspection points.
- Use compatible filter fabric with suitable overlaps above the cells.
