MP-S30B is a dark-green HDPE drainage plate for green roofs and landscaped deck systems. The 333 × 333 × 30 mm modules form a continuous open drainage layer below filter fabric and growing media, allowing excess water to move toward designated roof or podium outlets.
This product page preserves the original MP-S30B dimensions, performance entries, packing data, installation diagrams and site photographs. The complete roof build-up must still be designed around the project waterproofing, load, outlet layout and planting specification.

Roof-Drainage Function
The MP-S30B is intended as one component in a layered green-roof assembly. Installed above protected waterproofing, it creates open pathways for surplus water. A compatible filter geotextile above the modules helps prevent growing media from entering and blocking the drainage layer.
- Plan outlets, inspection points and perimeter details before laying the modules.
- Check that the protected substrate is clean and suitable for installation.
- Connect plates edge to edge and cut neatly around penetrations.
- Apply the specified filter fabric with secure overlaps.
- Protect installed drainage materials during placement of upper layers.
