MP-S30C is a modular HDPE drainage cell designed to create a continuous drainage layer beneath green roofs, podium landscapes, play areas and other landscaped construction. Its compact 333 × 333 mm format and interlocking layout help installers cover irregular areas while maintaining open paths for water movement.
This page retains the original MP-S30C technical data, installation drawings and project photographs. Final system design should be confirmed against the waterproofing build-up, filter layer, growing medium, traffic conditions and project drainage calculations.

Where the Drainage Cell Fits
In a typical green-roof or podium build-up, the MP-S30C drainage cell is installed above the protected waterproofing layer and below the specified filter fabric and growing medium. The open cell structure provides a route for surplus water while helping keep the drainage layer separated from soil particles.
- Confirm the waterproofing and protection layers before installation.
- Lay modules closely together and connect adjoining edges.
- Trim only where required at boundaries, outlets and penetrations.
- Install the specified filter geotextile with adequate overlaps.
- Keep outlets clear during placement of soil or other covering layers.
