MP-B25A is a green HDPE storage-and-drainage plate for planted roofs and landscaped decks. Its 25 mm profile combines shallow water-retention cavities with open drainage paths, helping the roof build-up hold a limited moisture reserve while allowing surplus water to reach designated outlets.
The model is distinguished from the black MP-B25C by its green colour and its own listed technical values. All original MP-B25A dimensions, performance entries, packing data, installation references and project photographs are retained below.

How It Works in a Planted Roof
The board is installed above the protected waterproofing and below the filter layer. Its formed surface retains a limited volume of water for the planting zone, while overflow paths help prevent surplus water from remaining trapped within the roof assembly. The project designer must confirm the complete layer sequence and drainage capacity.
Installation Guidance
- Verify waterproofing, protection and roof falls before laying boards.
- Arrange the plates consistently across the area and fit edges closely.
- Trim carefully around outlets, penetrations and inspection points.
- Lay the specified filter geotextile above the boards with secure overlaps.
- Protect the completed layer while placing growing medium and vegetation.
